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).
