The range of this species is extensive. It was originallj' obtained 

 near Redding in Northern California. My friend, James S. Lip- 

 pincott, has sent it to me from the extreme south of California, 

 San Diego. The Smithsonian Institution has a slightly differen- 

 tiated variety from Chihuahua ; and a specimen from my friend 

 Dr. Duges, from Guanajuato, Mexico, though rather young, is 

 apparently the same. I suspect that the Scaphiopus dugesi Brocchi 

 from that locality is the same species. 



This species is much like the Scaphiopus intermontanus described 

 further on. It is always smaller, and the middle pair of light dorsal 

 bands is nearly always wanting. It is still more different from the 

 S. varius, which has the vomerine teeth entirely posterior to the 

 nares, banded upper lip and marbled back.

Lizards are very abundant in this region, especially in the Wah 

 Wall Valley, on the west side of the range,

 Abundant near Salt Lake City. 



Scapbiopus intermontanus sp. nov. 



I took a specimen of this species within the limits of Salt Lake 

 City, and subsequently obtained three or four specimens from 

 Pyramid Lake, Nevada. It resembles the Spea hammondi more 

 than it does any other species. The frontoparietal bones, though
