This species is of rather variable coloration. The tj^pe (No. 2G18) is 

 a uniform light brown above and yellowish-white below. In two other 

 specimens from the same locality the dorsal tubercles are pile, with a 

 dark ring at the base. The latter is the prevalent coloration, for while 

 there are six specimens which show it, there is only one other of the 

 uniform brown tint. Specimens from Cape St. Lucas have red warts, 

 with a black ring at the base, and have the ground color of the sides 

 black besides. The hinder extremities have large blackish blotches, in- 

 closing tubercles which are pink. There is also a black spot on the 

 eyelid, one below the canthus rostralis running longitudinally, and one 

 which extends below and sometimes behind the tympanum. 



This is one of our best marked species. Its distribution extends fioni 

 western Texas from as far north as Fort Concho, and along both sides of 

 the boundary line between the United States and Mexico, to the Pacific 

 ocean. It is found as far south as San Antonio, in Texas (Marnock), 

 and in Lower California to the extremity of the peninsula (Xantus), and 

 in Mexico to Guanajuato (Duges). 



The paired gland-like ridges on the back, represented in the figure of 

 this species in the Eeport of the United States and Mexican Boundary 

 Survey, are merely the projections caused by the dorsal and sacral dia- 

 pophyses, somewhat exaggerated.
