Order Anura 



Family Bufonidae 



Bufo woodhousei fowleri Hinckley, Fowler's Toad 



Material. — Left ilium: USNM 404730, from near (ca. 4 cm above) 

 base of Unit Wl, SV-1. Two right ilia: USNM 404731, from Unit W2, 

 SV-1; USNM 404732, from Unit W3, SV-2. Two tibiofibulae: USNM 

 404733, from Unit W3, SV-1; USNM 404734, from Unit W3, SV-1. 

 Parasphenoid: USNM 404735, from Unit W2, SV-1. 



Remarks. — Holman (1967) and Wilson (1975) discussed characters 

 of the ilial prominence that allow separation of Bufo woodhousei fowl- 

 eri from the morphologically similar Bufo americanus. Bufo w. fowleri 

 is easily separated from its western counterpart B. w. woodhousei on the 

 basis of the much higher dorsal protuberance in the latter subspecies. 

 Bufo w. fowleri occurs in the area today, and occurs chiefly in sandy 

 areas around shores of lakes, or in river valleys. 



Family Ranidae 



Rana pipiens group, sp. indet. 



Material. — Right ilium: USNM 404736 (Fig. 5), from Unit W3, SV- 

 2. Two left humeri: USNM 404737, from Unit W3, SV-1; USNM
