Biographical Etymology of Marine Organism Names. P

Odostomia paardekoperi Van Aartsen, Gittenberger & Goud, 1998 was named for L.S. (Lou) Paardekooper, 1916-1966, member of the former Dutch mollusca working group.

Prof. Eystein Karl Mørner Paasche, (17 Sep. - Oslo) 1932-, Norwegian algologist, who was professor of Marine Botany in Oslo.

The gastropod name Alvania paatsi Hoenselaar & Goud, 1998 is named after the technician Mr. J.J.P. Paats, 19??-, for his participation in the CANCAP-expedition for marine biological research in the Canarian-Cape Verdean region of the North Atlantic Ocean (1976-1986). (Curator Henk K. Mienis, Tel Aviv Univ., kindly provided this information).

Stephan Ion Pace, (22 Nov. - London) 1872-1941 (13 Dec. - London), English malacologist (a student of Columbellidae), director of the Marine Biological Association of the W of Scotland , i.e. Millport, where he arrived from Plymouth in June 1905 until 1907 (when he resigned and was replaced by R. Elmhirst (q.v.)) [Columbella pacei E.A. Smith, 1895; also Columbella pacei Melvill & Standen, 1896, renamed C. stephani Melvill & Standen, 1897, after realizing that their first name was preoccupied ], in January 1904 married to the marine biologist Rose Mable Clark, 18??-19??, who worked on hydroids and bryozoans. He also studied holothurians, describing i.a. Cucumaria normani, a synonym of Aslia lefevrei. He was considered to dislike amateur researchers. From 1897 and three years he had been in Torres Strait and surroundings to conduct experiments with pearls in the pearl industry. After Millport he went to London, working part-time at the British Museum (Nat. Hist.), where his very good friend E.A. Smith (q.v.) was working. He took part in WWI, but later suffering from severe headaches, he never could continue his research work. Another namesake is the stalwart South Florida collector Robert (Bob) Pace, 19??-, from Miami [Ancilla (Amalda) pacei Petuch, 1987, Coralliophila pacei Petuch, 1987, Terebra (Strioterebrum) pacei Petuch, 1987, Conus pacei Petuch, 1987, Trivia (Niveria) pacei Petuch, 1987, Modulus pacei Petuch, 1987, Cerithium muscarum pacei Petuch, 1987, Cyclotheca pacei Petuch, 1987, Dermomurex pacei E. J. Petuch, 1988, Favartia pacei E. J. Petuch, 1988 (several of these species named for Pace's exploratory collecting in the Bimini area [thank you Riccardo Giannuzzi-Savelli for this information and for the information about Mrs. Alice Pace below])]. Mrs. Alice Pace, 19??-, Miami, may likely be R. Pace's wife and she is honoured in the names Muricopsis aliceae Petuch, 1987 and Cerithium eburneum aliceae Petuch, 1987. (Andrew Vik, Tampa, Florida kindly provided most of the information about R. Pace).

A. Pack (possibly identical with the US educator Arthur Newton Pack, (20 Feb. - Cleveland, Ohio) 1893-1975 (6 Dec.)), published on ciliates from the Great Salt Lake in 1919 and is honoured in the ciliate name Strongylidium packi Calkins, 1919.

Dr. Alpheus Spring Packard Jr., (19 Feb. - Brunswick, Maine) 1839-1905 (14 Feb.), was Professor of Zoology and Geology (from 1878) at Brown University (Rhode Island, USA) and professor of Biology and Geology at Bodwin College, Maine. As a boy, he collected and read about molluscs and their shells, encouraged by his father Prof. Alpheus Spring Packard Sr, 1798-1884, a professor of classical languages. Packard was well-known at this time in the Boston Society of Natural History, and was acquainted with Louis Agassiz (q.v.), A.A. Gould (q.v.), S. F. Baird (q.v.), and other mid-century naturalists in USA. Packard attended Harvard with Agassiz as his teacher. His youthful interests expanded to insects, fishes, and general marine zoology, a precursor of his adult contributions. He did well in so many fields that it is difficult to characterize any specialty. He traveled widely, forming strong connections with foreign scholars. One of the last of his 500+ publications was a biography (1901) of his intellectual hero Lamarck (q.v.). Packard is honored by his name attached to 3 insect genera and at least 39 (mostly insect) species. Within these is the amphipod Monoculodes packardi Boeck, 1870 [Pleurotomella packardii Verrill, 1872]. (Dr. D. Damkaer kindly provided this information).

Later (in 1882) he moved to his wife's home city Hamburg and founded the Natural History Museum there, becoming its first director. [Janua pagenstecheri (de Quatrefages, 1866), Lumbricillus pagenstecheri (Ratzel, 1869), Henricia pagenstecheri (Studer)]. A namesake and far away relative, Dr. Arnold Andreas Friedrich Pagenstecher, (25 Dec. - Dillenburg) 1837-1913 (11 June - Wiesbaden), Wiesbaden, was an entomologist and lepidopterologist. (Cédric Audibert, Muséum, CCEC, Lyon, kindly corrected an error).

Lacking information about Paine in the gastropod names Ocenebra painei (Dall, 1903) and Rictaxis painei Dall, 1903. A hobby entomologist, Charles Jackson Paine, (17 June - Weston, Massachusetts) 1876-1926 (4 Aug. - Vanceboro, Maine), businessman and banker is likely not the honoured person, but possibly John Howard Paine, (9 Sep. - Cleveland, Ohio) 1888-19??, (not identical with the identical namesake, the author of the well known "Home Sweet Home", who lived between 1792-1852), who in his teens was collecting mollusks together with the 8 years older Lowe (q,v.) assisted by mother and daughter Fancher and Fancher Sawin (see Fancher) studied by Dall (and later a disciple of V.L. Kellogg (q.v.)), or perhaps - considering his young age at the time - rather to his father Charles C. Paine. (28 Mar. - Painesville, Ohio) 1848- 19??, - and the Los Angeles Times credited the work to John's father:  "Avalon, July 14, Commodore C. C. Paine has begun a series of biological researches in the waters hereabouts.  He has procured a deep-sea dredge and is bringing up from the ocean depths things new, strange and beautiful.". C.C. Paine had been a soldier in the Civil War and the son John later studied entomology at Stanford (A.B. in 1912) as a student of V.L. Kellogg (see Heath) and published on Mallophaga and Lepidoptera at least until 1917. He worked for U.S. Dept. of Agriculture until about 1919 and as a portrait photographer during the 1920s. In 1931 he is listed as production manager in Washington, DC for Underwood & Underwood (photography). (David Hollombe, Los Angeles, kindly provided the lead to which Paine who is the most likely honouree and much of this information)

His dissertation in Leiden treated intestinal worms and he became Professor of Natural History in 1767, but he is most renowned for beeing contracted by the Russian government in 1768 to travel through Siberia during 6 years, where he collected huge amounts of material, which he later worked up and described in St Petersburg after returning there 30 July 1774. In 1793 he again was sent on a new expedition to the Crimea area, where he, his wife and daughter stayed during several years in an estate given to him by the emperess Katharina II, (who's favorite he was), but almost 70 years old he returned home to Berlin [Pallasea Bate, 1862, Cryptosula pallasiana (Moll, 1803), Stenurus pallasii (van Beneden, 1870), Amicula pallasii A.

Likely the self-taught British botanist and physician Dr. Edward Palmer, (12 Jan. - Norfolk County, England) 1831-1911 (10 Apr. - Washington D.C.), who mainly was active in USA (arrived there - Cleveland, Ohio - at age 18) and i.a. collected land shells in Mexico, described by Dall and also much other natural objects in SW USA, may be the honoured person.

The parasitic nematode name Cucullanus palmeri Crites & Overstreet, 1997 is a tribute to Ronnie G. Palmer, 19??-, for "superb technical assistance".

The Foraminiferan name Ammonia parkensoniana (d'Orbigny, 1839) is now accepted as A. parkinsoniana (d'Orbigny, 1939), so likely the author originally made a spelling error. If so, likely the English aphotecary surgeon and palaeontologist Dr. James Parkinson, (11 Apr. - Shoreditch, London) 1755-1824 (21 Dec.), who in 1811 published the 3:rd edition of "Organic Remains of a Former Word" and after whom Parkinson's disease is named, may be the honoured person.

She retired formally in 1973, but continued to work for another decade. Parker Bank in the Louisiana shelf is also named for her. An earlier namesake dealing with foraminiferans (known during his life mainly for his vertebrate skull studies) was the British physician Dr. William Kitchen Parker, (23 June - Dogsthorpe, near Peterborough) 1823-1890 (3 July - Cardiff), publishing together with T.R. Jones (q.v.) , W.B. Carpenter (q.v.) and others.

Lacking information about R.H. Parker in the amphipod name Bathyporeia parkeri Bousfield, 1973. Parker collected amphipods for Bousfield in the Hadley Harbor region.

Prof. Dr. Paul Woodburn Parmalee, (17 Oct. - Mansfield, Ohio) 1926-2006 (4 July - Knoxville), US zooarcheologist and palaeontologist, former director at the Frank H. McClung Museum at the University of Tennessee [Bellascintilla parmaleeana Coney, 1990]. (Dr. Jefferson Chapman, Director of the McClung Museum, kindly provided the date and birth place).

Juan José Parodiz, (Buenos Aires) 1911-2007 (24 Sep. - Allentown, PA), Argentine malacologist working at the Carnegie Museum, USA from 1951, is honoured in the genus name Parodizia Medina, 1959. He studied palaeontology and malacology at the Instituto Nacional Ciencias Naturales, and while serving in the Argentinian Navy, he took part in several oceanographical expeditions to southern seas and worked for almost 20 years at the Museo Argentino de Ciencias Naturales before going to USA. (André Tromboso, Brazil, kindly provided the information).

The decapod name Gelastocaris paronae (Nobili, 1905) is likely derived from Prof. Dr. Corrado Parona, (12 June - Corteolona) 1848-1922 (23 Aug.), who was a physician and Prof. of Zoology at the Genova University - he not only worked within zoology (see also A. Perugia), but also described som algae [Calceostoma paronai (Parona & Perugia, 1892), Encotyllabe paronae Monticelli, 1907], cooperating with his brother Dr. Ernesto Parona, 1849-1902, who also was a physician, within parasitology, although the most famous Italian scientist of this name was Prof. Carlo Fabrizio Parona, (8 Mar. - Melegnano) 1855-1939 (15 Jan.), working at the Univ. of Torino, geologist and palaeontologist with special regard to the 2ndary formations of N Italy. (Drs Stefano Palazzi & Maria Angela Stradi kindly provided this information).

Dr. Albert Eide Parr, (15 Aug. - Bergen) 1900-1991 (16 July - Wilder, Vermont), Norwegian born US ichthyologist, who had started studying Marine Biology as an assistant to Professor August Brinkmann (q.v.) at the Bergen Museum. Emigrated to the USA, where he in 1926 became an assistant at the New York Aquarium. He continued his research in Marine Biology and in 1927 he became curator of the Bingham (q.v.) collections, in 1938 he was appointed director of the Bingham Oceanographic Foundation (Peabody Museum) at Yale University of the Peabody Museum at Yale University. In 1942 (until 1959) he became director of the American Museum of Natural History, later working as a senior scientist at the museum [Sicyonia parri (Burkenroad, 1934)].

Walter James Parr, 1???-1949, was a well reputed amateur, who published on foraminiferans from Australia and New Zealand between 1930-50 [Parrina Cushman, 1931]. He died in a comparatively young age. An obituary (unseen by this compiler) was published oin 1950 by M.F. Glaessner in Australian Journal of Science 12(6): 211.

Ludwig Parreys, 1796-1879, Austrian (Wien) collector and dealer of natural history objects.

Either A. Parriaud , 19??-, or Henri Parriaud, 19??-, booth algal workers, is honoured in the green algal name Cladophora parriaudii van den Hoek. Henri Parriaud published at least between the 1950s and 1990s.

Admiral Sir William Edward Parry, (19 Dec. - Bath) 1790-1855 (8 or 9 July - Bad Ems), British Arctic Explorer and Hydrograper of the Navy.

Lacking information about Parseval in the bryozoan name Parasmittina parsevalii (Audouin, 1826). Not a common name, but Marc-Antione Parseval des Chênes, (27 Apr.) 1755-1836 (16 Aug.), French mathemathician and François-Auguste Parseval-Grandmaison, (7 May) 1759-1834 (7 Dec.), French poet, are a few authors with this name and of these likely the mathematician is the most probable honouree.

Lacking information about the malacologist M. Parth, 19??-, in the gastropod name Murexiella parthi R. Houart, 1993.

The Austrian geologist Paul Maria Partsch, (11 June - Wien) 1791-1856 (3 Oct. - Wien), is honoured in the foraminiferan name Adelosina partschi (d'Orbigny, 1846).

Amur M. Parukhin, (23 Feb.) 1928-1994 (25 May), Russian helminthologist born in Blagoveschchensk (the Amur river region), is honoured in the digenean name Elytrophalloides parukhini Gupta & Gupta, 1997. He studied at the Gorky Univ. at Nizny Novgorod under Prof. A. Sobolev and after that he went to the Far East, eventually reaching the Pacific Ocean, where he began to study helminths from marine fishes, which became a life-long work, although he later went to Sevastopol and spent his last 24 years in the Black Sea region (Prof. Jean-Lou Justine, Muséum National d'Histoire Naturelle, Paris, kindly provided a copy of a biographical note in Systematic Parasitology (1996) 34: 77-78).

Lacking information about the Indian actinian researcher Dr. Arun H. Parulekar, 19??-, (active with sea anemones during the late 1960s - later with i.a. polychaetes) in the actinian name Synantheopsis parulekari den Hartog J.C. and Vennam J., 1993 and in the octocoral name Sinularia parulekari Alderslade & Shirwalker, 1991.

Dermomurex agnesae Vokes, 1995 was named for Mrs Agnes Pas, 19??-. Likely also Dermomurex pasi E. H. Vokes, 1993 was named for the same person or a male person of the same family.

Norman Dale Paschall (24 Apr., Ava, Missouri, U.S.A.), 1924-2003 (28 May - MS), collector and student of marine molluscs. He exchanged widely with other collectors and published many articles in local conchological journals. He was well-known for his huge collection of worldwide Wentletraps, Fam. Epitoniidae. Unfortunately his mollusc collection was completely destroyed by a fire in the nineties. This loss affected him so immensely that it interfered heavily with his speech and memory. A rare Cone species found in Nicaragua: Conus (Leptoconus) paschalli Petuch, 1998, was named after him in appreciation for his assistance in collecting in the Bragman's Bluff area, the type locality of that Cone species. (Curator Henk K. Mienis, Tel Aviv Univ., kindly provided this information).

Dr. Adolf A. Pascher, 1881-1945, German microalgae worker during the first decades of the 20th century [Urceolus pascheri Skvortzow, 1924].

The Italian (Pisa, later Padova) copepod researcher Prof. Pasquale Pasquini, (19 Nov.) 1901-1977 (28 Jan.),who published on such creatures already in 1929 until at least the 1960s, is honoured in the harpacticoid name Psammopsyllus pasquinii Cottarelli, 1969.

Lacking information about Pasternak in the cirripedian name Teloscalpellum pasternakae Zevina, 1972, but possibly a tribute to the Russian pennatularian & antipatharian researcher Dr. Fedor Aleksandrovich Pasternak, 19??-, at P.P. Shirshov Institute of Oceanology, Moscow, (the husband of the tanaid researcher Dr. R.K. Kudinova-Pasternak (q.v.) - and their daughter Dr. Anna Pasternak, 19??-, is a plankton specialist at the Shirshov Institute), who began publishing around 1958 - or considering the female ending -ae perhaps more likely a tribute to his wife? (The isopod name Ceratoserolis pasternaki (Kussakin, 1967) must more likely honour him). The Israelic coral symbiont researcher Dr. Zohar Pasternak, 19??-, who also has published on Cirripedia, must be too young to be the candidate.

The marine gastropod Conus patae Abbott, 1971 was named after Mrs. Patricia ("Pat") Nelson Ware, 19??-, who collected part of the type material off Pompano Beach, Broward County, Florida, U.S.A. (Curator Henk K. Mienis, Tel Aviv Univ., kindly provided this information).

Mr. Somnuk Patamakanthin, (Damnoen Saduak, Ratchaburi Province) 19??-, Rawai Phuket, is honoured in the Thailandic gastropod names Conus patamakanthini Delsaerdt, 1997 and Surrepifungium patamakanthini A. & E. Gittenberger, 2005. He migrated to the Phuket area and started to collect shells, later establishing the Phuket Sea Shell Museum, an occupation taken over by his son Somwang Patamakanthin, 19??-, who is one of the largest shell collectors in Thailand.

Alexander Patience, (3 Dec. - Inverness) 1865-1954 (1 Jan.) , was a little-known amateur carcinologist (and property valuator) in Glasgow, publishing during the Edwardian era. He was the son of James Patience who became a Clyde river pilot. He worked all his life inGlasgow (in commerce as a house factor and valuator). He was active within the Glasgow Natural History Society and published 24 papers mainly on terrestrial isopods (woodlice) and marine Crustacea in the Clyde. He was friendly with Thomas Scott (q.v.) and Dr. John Nairn Marshall, Sheina Marshall's (q.v.) father. He named the amphipod Isaea elmhirsti Patience,1909 after the then Director of the Marine Station at Millport (Richard Elmhirst (q.v.)). Why his published contributions to crustaceology dried up after about 1910 remains mysterious. Two species of woodlice, Chaetophiloscia patiencei (R.S. Bagnall, 1908) and Miktoniscus patiencei Vandel 1946 are honouring his name. Vandel wrote that he assigned the name patiencei in the honour of the English zoologist who was the first to precisely describe a species of Miktoniscus (in Vandel, A. (1946) Crustacés isopodes terrestres (Oniscoïdea) épigés et cavernicoles du Portugal. Anaïs da Faculdade de Ciências do Porto 30: 135-427). (Prof. Geoff Moore, University Marine Biological Station Millport, who together with Geoff Hancock in 2004 finished an extensive biography of this amateur naturalist, kindly provided all this information, except the last eponym and its reference, which Glyn Collis, Isle of Bute kindly provided).

Patricia : (see also Hutchings or Oxner).

The diatom name Cocconeiopsis patrickae (Hustedt, 1955) must honour the algae worker Dr. Ruth Myrtle Patrick, (26 Nov. - Topeka, Kansas) 1907-, celebrated by a gala at her 100:th birtday.

Several species are named for him, but so far perhaps most non marine. However the foraminiferan name Nanosylvanella pattersoni Loeblich Jr. & Tappan, 1994 may perhaps be a tribute to him? {another picture}.

Robert Patterson, (18 Apr. - Belfast) 1802-1872 (14 Feb. - Belfast (died after a fall in his house)) , (with double t), owner of a mill-furnishing business in Belfast and one of the young men, who gathered with Dr. J.L. Drummond (q.v.) to shape the Belfast Natural History Society in 1821, is often mentioned as a collector for British naturalists of that time. He was the grandfather of R. Lloyd Praeger (see Southern). He is remembered in Iophonopsis pattersoni (Bowerbank, 1858), Sarsia pattersoni Haddon, 1886 and he seems to have collected the first specimens of Anomalocera patersoni Robert Templeton, 1838 at the outlet of Larne Lough, Antrim, Ireland and delivered his observations in a letter to the travelling surgeon and naturalist Dr. Robert Templeton, (12 Dec. - Cranmore, Belfast) 1802-1892 (2 June - Edinburgh), a son (2.nd of 5 siblings, having 4 sisters) of the well-known close friend of Joseph Banks, John Templeton, 1766-1825, who all his life was active as a naturalist at his estate a couple of kilometers from Belfast, e.g. making drawings of Irish cryptogams. According to Hopkinson 1913, Robert Templeton wrote an article in 1834 in Mag. Nat. Hist. (1) VII, pp. 129-131, using the pseudonym "C. M." - and he continued to publish (but usually using his own name) at least until 1858 (2 years before he retired in January 1860). Robert T. achieved his MD in Edinburgh in 1831 and joined the army as a surgeon between 1833-60, became widely travelled, e.g. staying at Sri Lanka between 1839-48, and produced a steady stream of natural history papers dealing with decapods, copepods, molluscs and insects. Possibly also Salenia pattersoni A. Agassiz, 1878, is named after Robert Patterson.

Choriplax pattisoni Ashby, 1921 was named for George Pattison, 18??-19??, lighthouse keeper at Cape Banks, South Australia.

Lacking information about Paul in the digenean name Metadena pauli (Vlassenko, 1931).

Who is Paul in the copepod name Phyllopodopsyllus pauli Crisafi, 1959? Possibly another harpacticoid, Oniscopsis pauliani Chappuis, 1954 may be connected with the same person? One possible candidate may of course be Paul Illg (q.v.).

Prof. Dr. Ferdinand Albert Pax, (30 Dec. - Breslau) 1885-1964 (11 Sep. - Bad Honnef), zoologist in Köln-Klettenberg, who in 1962 published his well-known book "Meeresprodukte, ein Handwörterbuch der marinen Rohstoffe". Pax had specialized in anthozoans after visits to the zoological stations in Trieste in 1906 (under Cori) and Bergen in 1907 (under Appelöf). [Parastephanauge paxi Dufaure, 1959]. He was a friend of W. Arndt (q.v.) and published some works together with him. His father was the botanist Ferdinand Albin Pax, (26 July - Köninginhof) 1858-1942 (1 Mar. - Breslau).

Baron Gustaf von Paykull (Paijkull), (21 Aug. - Stockholm) 1757-1826 (28 Aug. - Wallox-Säby (his estate in Uppland), Swedish poet and amateur collector and writer of insects. He donated his very huge natural history collection to the Swedish Academy of Science. (He had sent collectors to different parts of the world to enlarge his collections). This became the first collection in the Swedish Musium of Natural History, when it was founded and Paykull was knighted (baron) because of this. According to certain sources, he was a somewhat dubious person who did not hesitate to cheat and had cleptomanic inclinations.

Benjamin Charles Marie Payraudeau, (22 Mar. - logis de la Grande Forêt à La Réorthe) 1798-1865 (12 Jan.), disciple of Lamarck (q.v.) at the Jardin des Plantes, Paris.

The gastropod names Paziella Crosse, 1869 pazi Crosse, 1869, Poirieria pazi H. Crosse, 1869 and the bivalve name Nemocardium pazianum (Dall, 1916) .may possibly honour the Madrid museum researcher Patricio Maria Paz y Membiela, (17 Mar. - El Ferrol) 1808-1874 (11 Jan. - Madrid), .

Charles William Peach, (30 Sep. - Wansford, Northamtonshire) 1800-1886 (28 Feb. - Edinburgh), son of a saddler and harness-maker, who soon gave up this professon, becoming an inn-owner and farmer. Charles, beeing fond of books, went to school until 15 years old, when he had to assist his father in the inn and at the farm, but was often scolded for attending to books rather then the plough. When 23 years old, he was appointed as a riding officer in the coast-guard at Weybourn, in the port of Clay, Norfolk. In 1845 he moved to Cornwall and in 1849 to Peterhead, a town north of Aberdeen and then to Wick further north. He was a diligent collector of marine invertebrates for researchers, af first for Dr. Johnston (q.v.). He also himself published some articles - despite (at least initially) indigence, a family with 9 children to support and educate at an income of 4 shillings per day (in 1844). (One of his children, Benjamin Neeve Peach, 1842-1926, became a well known geologist). Participated during the 1860s in Jeffreys' collecting expeditions as a specialist on sessile fauna. (He retired from the coast-guard in 1861). Actually, as Peach had grown up in the inland, not having seen the sea until leaving his fathers house, he became fascinated of the sea when first confronted with it. He tells himself about how a most splendid specimen of Nemertesia antennina (Lamarck, 1816) found at the chimneypiece of an inn, where he stayed when going to his first job outside his family, excited his curiosity so much, so he had to find out what it was and after this his interest in marine life was awaked. He began collecting for the beauty, but in 1825, when meeting the Rev J. Layton, then at Chatfield, he became inspired also to collect all information he could find about the natural objects he came across, but not until 1841 at a meeting of the British Association at Plymouth, where he read a paper on Organic Fossils of Cornwall, he began reading or publishing papers [Peachia Gosse, 1855, Tricellaria peachi (Busk, 1851), Hymedesmia peachi Bowerbank, 1882].

Titian R. Peale : (see Dana). He should not be confused with his father, Charles Willson Peale, (15 Apr. - Chester, Maryland) 1741-1827 (22 Feb.), the portrait painter from Maryland, who at his own expences built the Philadelphia Museum, which started in 1786. Dr. D. Damkaer (in litt.) wrote that C.W. Peale's whole family was talented and that C.W. Peale named most all his sons after painters, except two, who were named for other celebrities. They were Raphaelle (the oldest), Rembrandt, Rubens, Charles Linnaeus, Franklin (for Benjamin Fr.), and (the youngest) Titian Ramsay. A couple of these made their name as artists. The father is best known now for his great portraits of the Founding Fathers of USA, G. Washington, Thomas Jefferson, etc [Loligo pealeii Lesueur, 1821].

Dr. William (Bill) Gordon Pearcy, around 1929-, PhD at Yale in 1960, born in a suburb of Chicago, Oregon State Univ., is honoured in the Mysida name Boreomysis pearcyi Murano & Krygier, 1985. He has mainly worked on fish and retired in 1998. Together with Dr. Peter C.

Rothlisberg is honoured in the names Spirorbis rothlisbergi Knight-Jones, 1978 and Brachycalanus rothlisbergi Othman & Greenwood, 1988.

Prof. Dr. Arthur Sperry Pearse, (15 Mar.) 1877-1956 (13 Dec.), US zoologist, who obtained his PhD at Harvard. Was for most of his life Professor of Zoology at Duke University, in North Carolina. Specialized in parasitic copepods, leaving about 25 publications between 1904 and 1952. Also authored general works on zoology. See his autobiography (1952) "Trying to be a Zoologist." Copepods named for him are Diaptomus pearsei Wright, 1927 and Paralebion pearsei Causey, 1953. [Phonorhynchus pearsei Ferguson, Strewalt & Kepner, 1940, Typhlatya pearsei Creaser, 1936]. (Dr. D. Damkaer kindly provided this information). A later namesake is Prof. Em. John Pearse, 1936-, Biology Department at University of California, Santa Cruz, who formally retired in 1994, has after that been working on invertebrates together with his wife Dr. Vicki Buchsbaum Pearse, 1942-, [Anthosactis pearseae Daly & Gusmao, 2007 - a whale carcass sea anemone] and her father Dr. Ralph Morris Buchsbaum, (2 Jan. - Chickasha, Indian Territory) 1907-2002 (11 Feb. - Pacific Grove, California), PhD at Univ. of Chicago in 1932, continuing at this university until 1950, when he moved to Univ. of Pittsburgh, but retired in 1972, moving to Pacific Grove, well-known for several invertebrate books, some of them together with his wife Mildred Shaffer Buchsbaum, (25 Apr. - Chicago) 1912-1996 (16 Jan. - Pacific Grove), and his sister Elizabeth Buchsbaum Newhall, 1909-1942, who helped with the illustrations.

(Prof. Jean-Lou Justine, Muséum National d'Histoire Naturelle, Paris, kindly provided a copy of a biographical note from Systematic Parasitology (1994)) 27: 237-238).

The holothurian name Pearsonothuria Levin, in Levin, Kalinin & Stonik, 1984 is in honour of Prof. Karl Pearson, (27 Mar. - Islington, London) 1857-1936 (27 Apr. - Coldharbour, Surrey), British mathemathician, who had spent some study time in Germany and there got the spelling of his first name changed from Carl to Karl, established the discipline of mathematical statistics and became a protegé and later the biograper of Francis Galton, Darwin's cousin.

The gastropod name Cymatium (Septa) peasei Beu, 1986. may possibly honour the American malacologist William Harper Pease, (Brooklyn, New York) 1824-1871, who in 1849 moved to Honolulu, from where he continued to work [Favartia peasei (Tryon, 1880), Conus peasei J. Brazier, 1877, Amygdalum peasei W. Newcomb, 1870, Hypselodoris peasei (Bergh, 1880)]. (Andrew Vik, Tampa, Florida kindly provided this information).

The West African polyplacophoran name Ischnochiton peasleri J. Thiele, 1910, seem to be a wrongly spelled variant of I. paessleri Thiele, 1910, and if so, likely a tribute to captain Richard Paessler (q.v.).

Jean Péchaud, (31 Oct. - Chavagnac (Cantal)) 1823-1886 (9 July - Saint-Saulge (Nièvre)), French Malacologist.

About the sponge name Hymenancora pecqueryi (Topsent, 1892)the athour told: "Je dédie cette espèce à mon excellent ami" M. J. E. Pecquery, 18??-, "professeur au Lycée du Puy.".

Harry Pederson, 1???-, McAllen, Texas, is honoured in the Caribbean shrimp name Periclimenes pedersoni Chace 1958. Pederson published on shrimps at least during the 1950s and the beginning of the 1960s (when he and Vern Pederson - a brother? were active on the Bahamas, later also becoming underwater agents for the Disney company), i.a. together with Limbaugh (q.v.) and between 1960-66 he was photographing decapods at the Bahamas together with Waldo Schmitt (q.v.).

The parasitic nematode name Anisakis pegreffii Campana-Rouget & Biocca, 1955 is likely a tribute to the Italian Prof. Giuseppe Pegreffi, 19??-, Direttore della Stazione Sperimentale della Sardegna, active at least from the 1930s to around 1960.

Lt. Col. Alfred James Peile, (5 Aug. - London) 1868-1948 (30 July - St. Thomas Hospital, London), British malacologist. There was also a malacologist A.H. Peile on Bermudas.

Prof. Benjamin Peirce, (4 Apr.) 1809-1880 (6 Oct.), superintendent of the US Coast Survey, in this respect the successor of Bache (q.v.).

His collections went to the Leiden museum (now "Naturalis"). He published six articles about his experience in West Africa in which he described among others three new non-marine species (a mammal and two reptiles). At least 14 species have been named after him (3 mammals, 4 birds, 4 fishes and 3 crustaceans). The aquatic species among them are the fishes Poecilophis peli Kaup, 1856 (now Echidna peli); Rhinoptera peli Bleeker, 1863; Larimus peli Bleeker, 1863 (now Pteroscion peli) and Polynemus peli Fowler, 1936, and the crustaceans Calappa pelii Herklots, 1851; Grapsus pelii Herklots, 1851 (now Goniopsis pelii) and Thelphusa peli  Herklots, 1861. For peli in a name of a mollusc reference is made to another Dutchman: P.L. van Pel (q.v. - under van Pel). (Curator Henk K. Mienis, Tel Aviv Univ., kindly provided part of this information)

Mr. Dov Peled, 1934-, from Tivon (Israel), shell collector and dealer, who collected the type material of Mitra (Nebularia) dovpeledi Turner, 1997 and donated the type material [Homalocantha dovepeledi Houart, 1982, Chicoreus (Triplex) peledi Vokes, 1978, Chicoreus (Triplex) dovi Houart ,1984].

Pergament : (see Gorbunov).

The amphipod name Hyale perieri (Lucas, 1846) may possibly be a name with an odd spelling, because Perier is likely not a common French family name, while Perrier is, so possibly the name may be a tribute to a person named so, but Edmond Perrier (q.v.) was of course too young at this occasion.

The well-known Petersen bottom sampler was constructed by him, but not the Petersen plankton net, which was made for Carl Chun (q.v.) by his friend the Russian Eugen (or Eugenio - real name likely Jevgenij) von Petersen, 18??-1???, who was an engeneer at Stazione zoologica in Napoli (Naples). He simply reconstructed the kind of net, which Palumbo (q.v.) had used.

Asteropterygion peterseni Kornicker, 1981 was named for Hans Petersen, 19??-, of Institute of Zoology, University of Hamburg, Germany. This is likely Hans E.E. Petersen, who in 1974 together with Gerd Hartmann published on the crustacean types in the collections of the Hamburg Museum.

Two other zoologist by the name of Ludwig Pfeiffer, 1842-1921 (published "Die Protozoen als Krankheitserreger") & Ludwig Pfeiffer, 1878-1926, may also be related. Whether they were related to the traveller and author Ida Pfeiffer, (14 Oct. - Wien) 1797-1858 (27 Oct. - Wien), from Vienna is unknown to the compiler, but not likely, because she was born Reyer and Pfeiffer was her married name.

Dr. Richard B. Pike, (2 Oct. - Kobe, Japan) 1911- (still active as a pastels painter in 2006), helped to collect copepods for the paper in which Sphaeronella pikei Green, 1958 was described. His father - from Surrey, England worked as a banker in Japan, later in New Zealand during WWI and several other countries, before moving back to UK (Jersey), while Richard was a child. An early interest in nature, e.g. butterflies, got him to leave a life as a hotel manager in spe and tried to become an artist, but finally chosed the career as a biologist, studying at the Univ. of Reading. He was a marine zoologist at the Scottish Marine Biological Station at Millport, Isle of Cumbrae, Firth of Clyde. At age 50, his wife thought that they should move and New Zealand, where he had spent some years as very yong, became the familys new home. After his retirement as a zoologist there, he started a new career as a pastels artist. (Dr. Sandy Bruce, Australia, kindly mentions: "I met him there (Millport) when he was particularly helpful to me when I was trying to study decapods during my military service in the late '50's. He was specially interested in decapod larvae, hermit crabs and their bopyrid parasites. He later transferred to the Zoology Department of Victoria University of Wellington, New Zealand, and finally, it appears, to the Fisheries Research Division, Ministry of Agriculture and Fisheries, Wellington. He last published in 1980. It was after him that I named the bopyrid Hypophryxus pikei Bruce, 1968").

Gaius Plinius Secundus, (Novum Comum, now named Como) 23-79 (25 Aug. - died when trying to save people from the well-known eruption of Vesuvius and trying to find out the reason for the eurption, because he was at this time commander of the Roman navy), Roman very productive author of i.a. Naturalis Historia (in 37 volumes - of which vol. 9 deals with water animals), from which later naturalist found much inspiration. Several modern taxon names have their roots in his works. One example is Mollusca, "soft animals", because Plinius used the word Mollia for some soft members of this group, namely the cephalopods. He is also known as Plinius the Elder, because his nephew Gaius Plinius Caecilius Secundus, 61 (or 62?)-113, who as young was adopted by the elder (brother of the younger's mother - beacuse the child's father had suddenly died) is known as Plinius the younger and also he published much, however not on natural history and his fame is mainly resting on his well written letters, which give good insight in how life in Rome was during his time. The younger Plinius was a friend of the historian Tacitus and the biographer Suetonius was employed by him.

He was a good friend and sea-going companion of Jules Richard (q.v.). Both men were principals on the cruises of Prince Albert I of Monaco (q.v. - under Grimaldi). Portier was a member of the Academy of Medicine, a professor at the University of Paris (Sorbonne), and a professor at the Institute of Oceanography (Paris). Portier's youthful interests were in entomology, in which he had a life-long connection. He was a member of the Entomological Society of France from 1888 (there is a short biography in their 1962 Bulletin 67:8-9). After some academic excursions into botany and medicine, Portier settled into physiology. Through his associates, he met Prince Albert and was one of his most faithful cruise-companions and collaborators. His studies of Physalia toxins led to the discovery and naming of anaphylaxis, the hypersensitivity of some individual organisms after repeated exposures to foreign substances. Unlike warfare, oceanography has had few deathless phrases. One has come down from Portier. During a particularly dangerous situation off Spitsbergen, the Prince was considering having all personnel but himself abandon ship. Portier said, "Your Highness, I prefer to die warm on board the ship than to live cold on the iceberg." (Dr. D. Damkaer kindly provided this information).

Dr. Joseph Poupin, 1957-, of France ( currently working at French Navy School, Brest. He is a research associate at the Muséum National d'Histoire Naturelle, Paris, and is specialized in systematics of tropical Decapoda, mainly those from French Polynesian Islands where he has made a lot of collections), is honoured in the shrimp name Periclimenes poupini A.J. Bruce, 1992 [Plesionika poupini Chan & Crosnier, 1997, Garthambrus poupini (Garth 1993), Strigopagurus poupini Forest, 1995, Sympagurus poupini R. Lemaitre, 1994, Chaceon poupini Manning, 1993, Nassarius (Zeuxis) poupini Cernohorsky, 1992]. (Dr. A.J. Bruce kindly supplied this information).

Count Louis François de Pourtalès, (4 Mar. - Neuchâtel) 1824-1880 (19 July - Beverly Farms, Massachusetts), followed his teacher Louis Agassiz (q.v.) from Switzerland to America, where he studied deep sea fauna in the Gulf Stream area [Atelecrinus pourtalesi Clark, 1907, Haliotis pourtalesi Dall, 1881, Ulophysema pourtalesiae Brattström, 1937, Pourtalesia A. Agassiz, 1869, Psolus pourtalesii Théel, 1886, Bathyplotes pourtalesii (Théel, 1886), Acanthoptilum pourtalesii Kölliker, 1870, Pourtalosmilia Duncan, 1884, Solariella pourtalesi Clench & Aguayo, 1939, Haliotis pourtalesi Dall, 1881, Epitonium pourtalesii (Verrill & Bush, 1880), Mangelia pourtalesii (Dall, 1881), Propeamussium pourtalesianum (Dall, 1886), Nectoteuthis pourtalise Verrill, 1883, Deltocyathus pourtalesi Cairns, 1979, Endopsammia pourtalesi (Durham & Barnard, 1952), Errinopora pourtalesii (Dall, 1884), Lepidotheca pourtalesi Cairns, 1986].

Dr. Arthur William Baden Powell, (4 Apr. - Wellington) 1901-1987 (1 July - Auckland), New Zealand malacologist, who collected one of largest and most comprehensive mollusc collections in the southern hemisphere. As young he had achieved some illustration education and was a good illustrator as well. It is said that he could be a bit shy among strangers, but a strong personality among friends. [Paracomitas powelli Dell, 1956, Amauropsis powelli Dell, 1990, Leucosyrinx bandenpowelli Dell, 1990, Splendrillia powelli Wells, 1990, Falsilunatia powelli Dell, 1956 likely Holspitotheres powelli Manning, 1993, likely Kurtziella powelli Shasky, 1971, Yoldiella powelli Dell, 1950, Cerithiopsis powelli B. A. Marshall, 1978, Brookula powelli Clarke, 1961].

Lacking information about Powell in the Indian Ocean skate Okamejei powelli (Alcock, 1898).

The diatom name Oestrupia powellii (Lewis) Heiden in A. Schmidt Atlas must be honouring either Henry Thomas Powell, 1925-, or William Nottingham Powell, 1904-, both algal researchers.

Lacking information about Power, in the lightfish name Vinciguerria poweriae (Cocco, 1838), if at all a person's name. Bonaparte 1840 created the genus name Poweria for it, but that is now considered as a synonym of Vinciguerria Jordan & Evermann in Goode & Bean, 1896, in which genus Witzell 1973 placed it. (Monterosato 1884 reused the name Poweria for a gastropod, but this name is of course a younger homnym).

Powhatan in the gastropod name Turbonilla powhatani Henderson & Bartsch, 1914 is likely not a person's name but the name of an algonquian "indian" tribe in North America.

The gastropod name Ocenebra empowlusi Abbott, 1954 is named for Marland Eckley Powlus, Apr. - Bloomsburg, Columbia County, PA) 1909-80 (Mar. - Port St. Joe, FL..). His niece Barbara Powlus Hays has kindly provided the following information: The childhood was chaotic. His father worked on the railroad which necessitated often changing location. Unfortunately, the marriage soured, and physical abuse caused my grandmother to divorce and thus ended the family circle. My grandmother moved to New Jersey with the boys to protect them and her from the father. She then raised the boys on her own supporting them from her luncheonette business on the boardwalk in Wildwood, New Jersey. Uncle Eckley was very creative and talented . He engaged in singing and drawing. He first made his living by doing charcoal sketches of people at the beach in Wildwood, NJ and singing in public places. Neither his daughter nor I know for sure, but we both suspect that he did not complete high school. My father did not either and he was the more intellectual of the two. Uncle Eckley married and shortly thereafter children came along. Uncle Eckley's free bohemian spirit and wanderlust would not let him stay in one place very long. If I were to compare him to some notable character it would be Ernest Hemingway. His charismatic personality endeared him to all in spite of obvious faults. It was his habit to pick up stakes and move southward get settled and then send for the family. At one time he worked at making mirrors. This pattern continued until he got to Florida approximately 1941 with five children and another born soon after his arrival there. He took a job in the shipyard, but such occupations could not hold him. Since he could no longer continue his southward pilgrimage on land, he took to the water which suited his restless spirit. He teamed up with a Dan Seiger who was a deep sea fisherman and shell collector. The shells they obtained appealed to my uncle's creative side and he acquired a large and varied collection. Certain folks interested in rare shells evaluated his collection and discovered that a shell of a certain type of deep sea murex was previously unidentified. At some future time parts of the collection found its way into other hands. His daughter mentioned both Ringling Bros Circus and the Smithsonian. A gentleman in St. Petersburg owns a copy of Abbott's book published in 1954 where the name is given to the gastropod. I am in contact with him. He is looking up the information in the book and I will speak with him again to see if there is more information to add. Uncle Eckley also engaged in shrimp fishing and spent the rest of his years working in the Gulf of Mexico and the Caribbean going as far South as Honduras. When he finally put the boat into the dock for good he took up residence on his daughter's property and ended his days in Port St. Joe FL..

Lacking data about the British Lord William Lyttleton Powys, Baron Lilford. He does not seem to have existed (see Baron Lilford) [Mangelia powisiana (Dautzenberg, 1887), possibly Polinices powisianus Récluz, 1844]. Likely the name William is a misunderstanding and the names are in honour of the landowner and ornithologist Thomas Lyttelton Powys, 4:th Baron Lilford, (18 Mar.) 1833-1896 (17 June), instead or the second name may have been a tribute to his father Thomas Atherton Powys, 3:rd Baron Lilford, (2 Dec.) 1801-1861 (15 Mar.).

Praeger : (see Southern).

Henry von Prahl, (4 Feb. - close to München) 1948-1989 (27 Nov. - between Bogota & Cali), decapod researcher, who was killed by a bomb exploding in an airliner. He followed his parents, when they emigrated to Colombia in 1953.

The gastropod name Conus pramparti Da Motta & Röckel, 1979 may possibly be a tribute to A. Prampart, 19??-,.

Tectidrilus pranzoi Erséus, 1987 is named for Mr. Alfredo Pranzo, 19??-, "who assisted most valuablly during the field trip to Sardinia".

Dr. Baini Prashad, (13 Mar.) 1894-1969 (18 Jan. - date of decease becomes clear after reading this document: about the will of his widow), Director of the Zoological Survey of India, published on "gephyreans" from Indian waters from 1919 at least until the late 1930s and is honoured in the echiuran genus name Prashadus Stephen & Edmonds, 1972, the shrimp name Caridina prashadi Tiwari & Pillai, 1971 and in the cephalopod names Octopus prashadi Adam, 1939 and Sepia prashadi Winckworth, 1936. (Andrew Vik, Tampa, Florida kindly provided the first name).

The natantian name Synalpheus paraneomeris praslini Coutiere, 1921 is not named directly after a person, but from the Isle de Praslin in the Seychelles. This island was named Isle de Palmes by explorer Lazare Picault in 1744, but during that time it was used as a hidaway by pirates and Arabic merchants. In 1768 it was renamed Praslin in honor of French diplomat César Gabriel de Choiseul, duc de Praslin, (15 Aug.) 1712-1785 (15 Nov.). (Dr. A.J. Bruce, Australia, kindly provided this information).

Prof. Dr. Ivan Pratt, (18 Sep.) 1908-1973 (14 Apr.), Oregon State University, Corvallis, published on e.g. trematodes [Theristus pratti Murphy & Canaris, 1964, Calliopiella pratti J.L. Barnard, 1954].

Henry Sherring Pratt, (18 Aug. - Toledo, Ohio) 1859-19??, US zoologist / parasitologist, who published on most animals, but usually excluded insects and birds and kept publishing at least until 1935. Miss Anne Pratt, (5 Dec. - Strood, Kent) 1806-1893 (Shepherd's Bush, London), British botanist and publisher of "Things of the Sea-coast" during the mid 19:th century, is a namesake like the professional animal collector Antwerp Edgar Pratt, 1853?-1924? (was buried 8 Jan. that year at Teddington Cemetary after dying at age 70), in Isle of Wight, who collected animals (and plants) in China, New Guinea and South America before selling them. He was the father of H.S. Pratt and Felix Pratt, honoured in a lepidopteran name prattorum, together with the father,

The British (Cambridge?) zoologist Edith Mary Pratt Musgrave, 18??-19??, married Musgrave in 1909, worked on Octocorallia, polychaeta and bipolarity during the 1890s and the first decade of the 20:th century and is honoured in the names Cladiella prattae Tixier-Durivault, 1944 & Sinularia prattae Verseveldt, 1974.

Dr. Johann August Ludwig Preiss, (21 Nov. - Herzberg am Harz) 1811-1883 (21 May - Herzberg am Harz), was a German plant collector, who i.a. collected huge amounts of algae in Western Australia, between 1838-42. He is remembered in the red algal name Acrothamnion preissii (Sonder) Wollaston.

Prof. Dr. Eugène Marcel Prenant, (15 Jan. - Champigneulles) 1893-1983 (15 July - Paris), French bryozoologist. Professor at Sorbonne [Prenantia Gautier, 1962, Cercaria prenanti Arvy, 1949, Bolteniopsis prenanti Harant, 1927, Bugula prenanti Castric-Fey, 1971, Tracheloraphis prenanti Dragesco, 1960]. However Rajonchocotyle prenanti (Saint Remy, 1890) is of course too early for honouring him and is likely a tribute to his father and older namesake Prof. Dr. Louis Auguste Prenant, (5 Nov. - Lyon) 1861-1927 (Paris), who published Traité d'histologie, a reference for cell biology. He was professor in Nancy together with Pol Bouin (q.v.), who succeded him when he in 1908 left for a professorship in Paris. Marcel was active politically as a militant communist and took part in WWII as an active anti-fascist, but was captured by Gestapo in 1944 and was deported to the Neuengamme Camp and witnessed in Hamburg after the war about the cruelties in this camp.

Prof. Aleksandr Romulovitch Prendel, 1888-1969, marine scientist honoured in the copepod name Oncaea prendeli Shmeleva, 1966. He was working at the hydrobiological station in Odessa.

Preslia - The Journal of the Czech Botanical Society is named for them.

The gastropod name Granoturris presleyi Lyons, 1972 is a tribute to Robert F. Presley, 19??-, St. Petersburg, Florida, a zoologist, who took part in the Hourglass cruises in the Gulf of Mexico 1965-67, possibly identical to a cousin of a well known music artist.

The bone-eating siboglinid Osedax frankpressi Rouse, Goffredi & Vrijenhoek, 2004 is honouring Dr. Frank Press, (4 Dec. - Brooklyn, New York) 1924-, (PhD at Columbia Univ. in 1949) former U.S. presidential science advisor, president of the U.S. National Academy of Sciences, and chair of MBARI Board of Directors, "for his distinguished service to science".

Looking for information about Nicolò Prestandrea, 1???-18?? (still living in 1843 and as it seems also in 1850), chemist / pharmacist from Messina, who in 1833 published a Sicilian paper, in which some essential marine crustacean genera were described. Together with Cocco (q.v.) he also used the botanical garden which Francesco and Antonino Arrosto had created in Messina for botanical education as part of the courses of the "Accademia Carolina" [Euchaeta prestandreae Philippi, 1843]. His nephew, the botanist Antonio Prestandrea, 1817-1854, from Catania, Sicily, was a member of "Accademia dei Periculanti"; - whether their danger was Etna or something quite different is not known to the compiler.A "Memorio di Nicolò Prestandrea" was published in Palermo in 1883 so he must have died before (possibly long before) that year.

Hugh Berthon Preston, (London) 1871-1945 (4 Feb. - Ireland), British Malacologist working in East Africa. He had been a tea planter in Ceylon, before becoming a professional malacologist.

Jean Louis Prevost, (1 Sep. - Geneva) 1790-1850 (14 Mar. - Geneva), French-Swiss physiologist / embryologist [Hyale prevostii Milne Edwards, 1830].

Miss Sadie F. Price, 1849-1903, US Malacologist and plant collector.

Lacking information about Price in the cephalopod name Octopus pricei (Berry, 1913).

Charles Prideaux, (2 Jan. - the 'Vine House' - Kingsbridge) 1782-1869 (!9 July - Kingsbridge), one of W.E. Leach's (q.v.) friends (& his second-cousin, - Charles Prideaux's grandmother being sister of W.E. Leach's maternal grandmother), who collected many specimens for him, especially from Plymouth Sound. Not much is known about Prideaux, except that he came from a family of quakers (became interred in the Friends' burying-ground, at Kingsbridge) and - like Leach - came from an ancient Devon family including several lawyers in the Plymouth area, all descendants of Paganus de Prideaux, who came over from Normandie with William the Conqueror. His parents were George 1744-1815, and Anna (née Debell Cookworthy) Prideaux, 1751-1836, who got 10 known children: George Cookworthy, 1775-1841, Philip Cookworthy, 1776-1842, William Prideaux, 1778-1843, Walter Prideaux, 1779-1832, Charles, Anna Prideaux, 1784-1861, Sarah, 1786- (married Robert Philip Fox in 1812), Rachel 1787-, (daed in infancy), Dorothy Cockworthy, 1790- (married Samuel Tregelles in 1812), Rachel Cookworthy, 1792- (married Robert Were Fox in 1815).. He was evidently not a lawyer himself, but together with his brother William he had become involved in a company selling clean drugs and chemicals for medical purposes to physicians and surgeons - Cookworthy, Fox, Prideaux and Balkwill, so during spare time he could cultivete his interest in natural history and collected i.a. birds, but his main interest was marine biology. He lived in Kingsbridge, SE of Plymouth at about the same time as Montagu (q.v.) did, and Leach may perhaps have met Montagu through Prideaux, who had become a friend of Montagu earlier. Prideaux helped Leach arrange the British shells in the Museum at the end of 1816 and Leach took specimens from Prideaux's collection for the museum. Leach described Prideaux in a letter to Alexander MacLeay (Secretary of the Linnean Society) as,"decidedly [Britain's] best conchologist as far as relates to the knowledge of the species.". Prideaux spent several years in Plymouth in the beginning of his life, but then moved back to his home town and was a F.L.S. for upwards half a century, but became confined to his bed for several years during the last part of his life, through illness and infirmity, although his intellect remained bright to the last.

Priestley in the gastropod name Trophon priestleyi Ch. Hedley, 1911 : (see the Terra Nova expedition, 1910-).

Lacking information about Sr. Prieto in the gastropod names Natica prietoi J. Hidalgo, 1873 (collected by Prieto at Menorca) and Eubranchus prietoi Llera & Ortea, 1981, but considering the time lapse between the two names, likely two different persons may be honoured.

Also Prouho's membrane in cidaroids is honouring his name. Dr. John M. Lawrence has translated Prouho's work on Cidaris to English. When reading his article, one can see that he was very careful and accurate.
