AMPHIBIANS AND REPTILES FROM ECUADOR, VENEZUELA, AND YUCATAN. 

 BY HENRY W. FOWLER. 



Several collections of herpetological specimens have recently been 

 acquired by the Academy of Natural Sciences of Philadelphia. 

 Important among them are those forming the basis of this paper. 

 Several species, apparently new, are described and figured. All the 

 figures are drawn to scale, the accompanying line signifying ten 

 millimeters. 



ECUADOR. 



The collection from this country was made on the western slope 

 of the Andes, from Guayaquil to Quito, during 1911, by Mr. Samuel 

 N. Rhoads. The fishes were reported by the writer during the same 

 year in these Proceedings. Since then all the collections Mr. 

 Rhoads made were purchased by the Academy. In this connec- 

 tion I wish to express thanks to Mr. Rhoads for the appended notes 

 relating to the habits of the various species. 



AMPHIBIA. 



BUFONID^. 

 Bufo marinus (Linnaeus). 



Two from Bucay. 



Bufo typhonius (Linnaeus). 



Seven from Bucay. Found only under stones and logs, in woods 

 and banana plantations. 



This very variable species ranges over the greater part of South 

 America, and in this connection I have examined many examples 

 from th€ following localities: Chapada, near Cujaba in Matto 

 Grosso (H. H. Smith)-; Upper Punes River (Steere) ; Bahia (Cope) 

 in Brazil; Peru(Orton); Pebas (Orton), Ecuador; Surinam (Bering). 

 Some examples show the hght vertebral line very conspicuously, 

 and in others it is wanting. Variation in the color of the back is seen 

 from nearly uniform brownish specimens to those greatly blotched. 

 Some large examples have nearly all the lower regions blackish, and 

 they also show the postorbital flange greatly elevated. The Bucay 

 specimens do not show any parietal ridges extending from the post-
