A review of Chelonian type specimens (order Testudines) Author Iverson, John B. text Megataxa 2022 2022-01-25 7 1 1 85 journal article 20418 10.11646/megataxa.7.1.1 bd1f1932-a0fa-4daf-af9f-cc52c932ed40 2703-3090 5964441 3BD32BFF-0402-47FB-A9EE-FE08E260793D 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.
