" Schmidt and Owens (Publ. Field Mus. Nat. Hist., zool. ser., vol. 29, 1944, p. 101) regard this as a species 

 distinct from that to which elegans belongs, but the distinguishing criterion mentioned appears to be one 

 that in reality separates males from females of either form. We have not examined the specimens but re- 

 gard all Pseudemys reported by Schmidt and Owens as P. s. elegans.
