Eretmochelys imbricata (Linnaeus 1766:350) Holotype: UPSZTY (formerly UUZM) 130, according to Smith & Smith (1980:280) and Cogger et al. (1983:72) with hesitancy, although Wallin (1985:128) indicated that no type material still exists. However, Wallin (1985:128; 2001:126) demonstrated that Linnaeus’ concept of Testudo imbricata was confused with Testudo (now Caretta) caretta and perhaps Testudo (now Chelonia) mydas; UPSZTY 130 is a Chelonia mydas (Wallin 2001:126). Testudo nasicornis Bonnaterre 1789:21 Holotype: Not located (Cogger et al. 1983:72), but illustrated in the original description (Pl. 13, Fig. 3), and illustration designated holotype by TTWG (2009:341, comment 9.7). Chelonia pseudomydas Lesson 1831:299 Holotype: Not designated (Cogger et al. 1983:72), possibly MNHN. Chelonia pseudocaretta Lesson 1831:302 Holotype: Not designated (Cogger et al. 1983:72), possibly MNHN. Caretta bissa (Ruppell 1835:4) Syntypes (at least 2): SMF 3183 (Mertens 1922:169) and 7886; SMF 7886 designated as lectotype by Mertens (1967:52). Eretmochelys squamata Agassiz 1857:382 Syntypes (2): MCZ 1415-16; MCZ 1416 designated lectotype by Smith & Taylor (1950:17). Caretta squamosa Girard 1858:442 Holotype: Not located; presumably in the USNM, but not listed by Cochran (1961) or Reynolds et al. (2007). Caretta rostrata Girard 1858:446 Syntypes (2): USNM 257185 (formerly USNM Osteo 12387) and 257186 (formerly UNSM Osteo 12388)(Cochran 1961:228; Reynolds et al. 2007:10). Onychochelys kraussi Gray 1873:398 Syntypes (2): BMNH 1947.3.4.37 (formerly 1873.3.13.4) and 1947.3.5.43 (formerly 1873.3.13.3)(Cogger et al. 1983:72). Note that Gray (1873:93) reported only a single BMNH specimen of this taxon: 1873.3.13.2.
