THE BATKACHIA OF NORTH AMERICA. 



273 



The above measurements of the posterior leg show that tlie greater 

 part of the femur is embraced ia the integument of the body. 



This toad has very much the appearance of one of the Scaphiopidoe, 

 and it is not unlikely that its habits are, like theirs, subterranean. 



The specimen figured as Bufo speciosus by Baird in the Eeport of the 

 Mexican Boundary Survey (No. 2611), from Pesquiera, in Nuevo Leon 

 is not typical of the B. conipactilis. It has feeble traces of the crania 

 crests of the Bufo cognatus, and some large brown dorsal spots not found 

 in other specimens. Three specimens from Kansas (3994) possess sirnilar 

 rudimental crests, and a fiftli specimen of the same character was sent 

 me from the Wichita Eiver, in central northern Texas, by Jacob Boll. 

 These specimens foresliadow the characters of the Bvfo cognatus, while 

 not approaching it in the development of the cranial crests. In the 

 Dallas specimen the dorsal spots are of medium size, while in those 

 from Kansas they are very small or wanting. I suspect that the cranial 

 characters belong to a race which ranges farther north than the true 

 Bufo compactiUs, which may at some time be regarded as a subspecies, 

 under the name of B. compactilis speciosus. The true B. compactilis 

 occurs in southwestern Texas, and ranges as for south in Mexico as 

 the Isthmus of Tehuantepec.

Superciliary crests not distinct on the muzzle, parallel, nearly straight, 

 terminating abruptly posteriorly in a transverse elevation. The latter 

 meet on amiddle line, form ing a transverse ridge, with an abrupt descent 

 to the nape. Externally they extend but a short distance, leaving no 

 representations of the postorbital ridges except a few tubercles in one 

 or two of the specimens. A small supratympanic tuberosity. No pre- 

 orbital ridge. Muzzle vertical at end; nostrils terminal, Membranum 

 tympani a vertical oval, two-thirds the diameter of the eye, Parotoid
