 the calf; a cutaneous fold along the inner edge of the tarsus: toes 

 moderate, half-webbed, with single-rowed subarticular tubercles. 

 Upper parts with irregular, depressed, distinctly porous warts. Above

Bescription. — Bufo carens is a very remarkable species, on account 

 of its physiognomy and the apparent absence of parotoid glands. The 

 latter character has even been regarded as of generic value, and 

 this species has become the type of a genus, Schismaderma, Smith. 

 The parotoids, however, are not absent, as Dr. Giinther has shown ; 

 and this species must evidently be placed in the neighbourhood of 

 B. regularis. I cannot, therefore, admit Schismaderma, even as a 

 subgenus. 



The head is very short and small with regard to the trunk ; the 

 snout is vertically truncated ; and the loreal regions are nearly vertical. 

 The nostrils are about equally distant from the anterior corners of the 

 eyes and from the tip of the snout ; the space between them equals
