A review of Chelonian type specimens (order Testudines) Author Iverson, John B. text Megataxa 2022 2022-01-25 7 1 1 85 journal article 10.11646/megataxa.7.1.1 bd1f1932-a0fa-4daf-af9f-cc52c932ed40 2703-3090 5964441 Chrysemys picta marginata Agassiz 1857:439 Syntypes (18, according to Barbour & Loveridge (1929:241) : MCZ 1780 ( 3 specimens ), 1789– 1790 (3), 1791 (3), and 1796 (9); UIMNH 41529 (formerly MCZ 1796; Smith et al. 1964:35 ); NMW 26218 ( Tiedemann et al. 1994:11 ); and UMMZ 63519 ( Peters 1952:54 ; Kluge 1984:79 ). However, current MCZ on-line catalogue lists 1784, 1792, 182588, 182590, 182594-96, 182599, 182601-02, and 182604-06 as syntypes , most of which are presumably renumbered early catalog numbers with multiple specimens. Type locality restriction by Schmidt (1953:99) by default makes one of the three MCZ 1780 specimens the lectotype ( Smith & Smith 1980:423 ).
