Terrapene triunguis ( Agassiz 1857:445)

Syntypes (18, according to Ernst & McBreen 1991:6, although there is some uncertainty about which are valid syntypes; J.P. Rosado, pers. comm. to John Iverson): Barbour & Loveridge (1929:241) reported only seven syntypes (MCZ 1519–1525, though 1519 included eight specimens; MCZ on-line catalogue), and Cochran 1961:230 listed only two syntypes (USNM 86871 and 86872); however, according to Reynolds et al. (2007:12) the syntypes include MCZ 1519 (originally eight specimens; seven now recatalogued as MCZ 184569-75), and 1522-25, and USNM 86871 and 86872 (both formerly MCZ 1519, and listed as the only syntypes by Cochran 1961:230). Possible additional syntypes include USNM 22, 7545, 7546 (originally four specimens, although two were a skull and shell from the same specimen; but only two specimens are currently catalogued with that number, and the fourth was given a new number), 131838 (formerly one of the specimens numbered 7546), and 213736 (formerly 7545)( Reynolds et al. 2007:13). ZSM 18/1932 (formerly in the MCZ, and possibly one of series numbered MCZ 1519) is now lost, Franzen & Glaw 2007:206).
