COMMENT: Gaffney and Meylan 1988, Phylogeny Turt. :157-219, present a phylogeny and systematic review of all living and extinct turtles to genus. Gaffney 1975, Bull. Am. Mus. Nat. Hist. 155:387-436, studied the phylogeny of turtles, reviewed the history of classification, and presented a new classification. Bickham and Baker 1976, Chromosoma (Berl.) 54:201-219, and Bickham and Carr 1983, Copeia (4):918-932, discussed phylogeny of turtles and reached conclusions partly at variance with Gaffney. Wermuth and Mertens 1977, Das Tierreich 100:1-174, presented synonymies for most of the species. Dowling and Duellman 1978, Syst. Herpet. 53.1-68.1, presented a review of the literature of turtle systematics. Iverson 1986, Checklist Turt. World :1-282, reviewed all species and many subspecies. Pritchard 1979, Encycl. Turt. :1-895, summarized much of the information on turtle biology and (p. 98-103) compared the various higher classifications. Pritchard and Trebbau 1984, Turt. Venezuela 2:1-402, presented detailed synonymys, historical reviews, and biological data on many families. Mlynarski 1976, Handbuch Paläoherpetol. Testudines 7:1-130, reviewed the fossil forms as well as their taxonomy. Smith and Smith 1979, Synops. Herpetofauna Mexico Turt. 6:17-19, summarized the nomenclatural history of the group name and argued for the retention of Linnaeus as the author of the group name.

Gaffney 1975, Bull. Am. Mus. Nat. Hist. 155:387-436, also showed close relationship to Trionychidae; but see Frair 1983, J. Herpet. 17:75-79. See Cogger, Cameron, and Cogger 1983, Zool. Cat.

FAMILY: Cheloniidae Gray 1825, Ann. Philos. (2)10:212.
DISTRIBUTION: Circumtropical, seasonally following warm currents deep into temperate regions.
COMMENT: Taxonomy history and literature review for Mexican species supplied by Smith and Smith 1979, Synops. Herpetofauna Mexico Turt. 6:254-255, who suggested the family name should be attributed to Gray 1825 and that the Carettinae and Cheloniinae were only tribally, and not subfamilially, distinct. Frair 1979, Herpetologica 35(3):239-244, and Frair 1982, Comp. Biochem. Physiol. 72B:1-4, suggested that the Cheloniidae and Dermochelyidae were only distinct at the level of subfamilies. He also suggested that the former subfamilial arrangement, Cheloniinae and Carettinae (the latter for Caretta and Lepidochelys) was untenable, because Eretmochelys was more closely related to Lepidochelys and Caretta than to Chelonia. Reviewed by Pritchard and Trebbau 1984, Turt. Venezuela 2:269-280, who considered the Dermochelyidae to be distinct from the Cheloniidae, and argued against tribal or subfamilial division of the latter family on the grounds of uncertain allocation of the many fossil genera and ambiguous relationships among the living species. Synonymies and literature review of Australian species in Cogger, Cameron, and Cogger 1983, Zool. Cat. Australia Amph. Rept. 1:66-70. Zangerl, Hendrickson, and Hendrickson 1988, Bishop Mus. Bull.

DISTRIBUTION: All tropical and subtropical seas.
COMMENT: Stejneger 1907, Bull. U.S. Nat. Mus. 58:509, points out that Chelonia as originally published by Brongniart 1800 is a nomen nudum. Pritchard and Trebbau 1984, Turt. Venezuela 2:279, agree and indicate that Latreille 1801, apparently used Chelonia as a "famille" name and not as a genus. Chelone Brongniart 1805 seems to be the valid name.

FAMILY: Chelydridae Gray 1870, Suppl. Cat. Shield Rept. British Mus. 1:8.
DISTRIBUTION: Southern Canada to Ecuador.
COMMENT: Gaffney 1975, Fieldiana: Geol. 33(9):157-178, studied the phylogenetic relationships of the genera, and included Platysternon in this family. Whetstone 1978, Univ. Kansas Sci. Bull. 51:539-563, also studied the phylogeny of the Chelydridae and removed Platysternon. Frair 1982 Copeia (4):976-978, showed Chelydra and Platysternon have quite different electrophoretic patterns. Chkhikvadze 1971. Bull. Acad. Sci. Georgian S.S.R. 62:489-491, commented on the possible origin of the family. See comment under Testudinidae: Platysternidae.

Chelydra serpentina (Linnaeus 1758), Syst. Nat., ed. 10, 1:199.
ORIGINAL NAME: Testudo serpentina.
TYPE: Holotype: originally in NRM, lost according to Andersson 1900, Bihang Kong. Svenska Vet. Akad. Handl. (4)26(1):4,23. Iverson 1986, Checklist Turt. World :13, cites ZIUS GA 49 as the holotype.
TYPE LOCALITY: "Habitat in calidis regionibus"; restricted by Smith and Taylor 1950, Bull. U.S. Nat. Mus. 199:21, to "New Orleans, La" (= New Orleans, Louisiana), U.S.A.; restricted by Schmidt 1953, Check List N. Am. Amph. Rept., ed. 6:86, to "vicinity of New York City," New York, U.S.A.
DISTRIBUTION: From southern Canada through the eastern and central U.S.A., introduced in Arizona, California, Nevada, and Utah; southeastern Mexico south to Ecuador.
COMMENT: Considered by some authors to contain several species, Chelydra rossignoni from southern Mexico to Costa Rica, Chelydra acutirostris from Panama to Ecuador, Chelydra osceola from peninsular Florida, U.S.A., and Chelydra serpentina from the eastern U.S.A. However, Feuer 1971, Herpetologica 27:379-384, reported intergradation between Chelydra serpentina serpentina and Chelydra serpentina osceola. Reviewed by Medem 1977, Caldasia 12(56):41-101.

ORIGINAL NAME: Chelonura temminckii.
TYPE: Holotype: MNHN-AC A.4540. See comment below.
TYPE LOCALITY: "a tributary stream of the Mississippi, which enters that river above Memphis, in West Tennessee," U.S.A.; restricted to the Wolf River, Shelby County, Tennessee, U.S.A., by Bour 1987, J. Herpet. 21(4):342.
DISTRIBUTION: Gulf of Mexico drainages of the southeastern U.S.A., from Suwannee River in the east to San Antonio River in the west.
COMMENT: Bour 1987 J. Herpetol. 21(4):340, indicates that in the early 1830's Lesueur and Harlan sent specimens of M. temminckii to the MNHN, while Troost sent specimens to the RMNH. Since MNHN-AC A.4540 was received in the right time period and has measurements that match skull dimensions in the original description, Bour 1987 J. Herpetol. 21(4):343, concluded it was the holotype. However, Hoogmoed reports RMNH 6166 is the holotype. Reviewed by Pritchard 1982, Rep. World Wildl. Fund 124 p.

FAMILY: Dermochelyidae Wieland 1902, Am. J. Sci. (4)14:95-108.
DISTRIBUTION: All tropical and temperate marine waters.
COMMENT: The oldest family name is Sphargidae (Gray 1825, Ann. Philos. 10(2):193-217), but it was replaced by Dermochelydidae after Baur 1888, Zool. Anz. 11(270):44-45, established that the genus name with priority was Dermochelys Blainville 1816 and not Sphargis Merrem 1820 or Dermatochelys Wagler 1830. Dermochelydidae also is the spelling dictated by classic Latin which separates the vowels "y" and "i" with a consonant to ease pronunciation; see Wermuth and Mertens 1977, Das Tierreich 100:99. The presently accepted spelling was first used by Baur 1890, Am. Naturalist 24:530-536, and fixed by Wieland 1902, Am. J. Sci. (4)14:95-108. An often seen variant spelling, Dermochelidae, results from the inadvertent omission of the "y"; see Smith and Smith 1979, Synops. Herpetofauna Mexico Turt. 6:231-233. Reviewed by Pritchard and Trebbau 1984, Turt. Venezuela 2: 249-252, and Smith and Smith 1979, Synops. Herpetofauna Mexico Turt. 6:231-253. Synonymy and literature review in Cogger, Cameron, and Cogger 1983, Zool. Cat. Australia Amph. Rept. 1:75-77. Frair 1979, Herpetologica, 35:239-244, and Frair 1982, Comp. Biochem. Physiol. 72B:1-4, suggested that the Dermochelyidae and Cheloniidae were distinct only at the level of subfamily, but this was not accepted by Pritchard and Trebbau 1984, Turt. Venezuela 2:269-280.
