Graptemys pulchra Baur 1893:675

Syntypes (originally believed to be 2 specimens, but see below; photographed in Lindeman 2013:281): USNM 8808 (2 specimens); the skull of one of the syntypes was removed and apparently catalogued as USNM Osteo 29526, but now both the specimen and its skull are numbered USNM 318254 (Reynolds et al. 2007:15). Cochran (1961:231) and Lovich (1985) recorded both USNM 8808 and Osteo 29526 as the syntypes. USNM 8808 designated lectotype by Lovich & McCoy (1992:304). FMNH 22171 (reported as “cotype” by Marx 1958:449) and USNM 220884 (not reported by Reynolds et al. 2007) were subsequently identified by Lindeman (2013:280) as additional syntypes. A detailed history of the confusion regarding the types of this species appears in Lindeman (2013:279–281).
