HAB. Sonorun Region. 



Abundant in Eastern Utah, Nevada, Colorado, New Mexico, and Ari- 

 zona, but, singularly enough, had not been seen until discovered by Dr. E. 

 Coues, U. S. A., in New Mexico. Specimens were procured of all ages 

 and sizes during the expeditions of 1872, 1873, and 1874. 



Is most closely allied to B. americanus, but differs in having shorter 

 and more elevated cranium, longer and larger hind limbs, and more acumi- 

 nate parotoid glands. The specimen No. differs from the type in having 

 the tympanum one-half size of eye, the tarsus reaching to the end of the 

 muzzle.
