Orver II. SAURIA—THE LIZARDS. 
Exe@arta Princiris. (Baird and Girard.) 
Spotted Elgaria. . 
I obtained specimens of this lizard at Walla-walla 
and on the banks of the Chelukweyuk river. I found. 
it in both cases under stones, in turning them over to 
hunt for beetles. Dr. Suckley records it as being found 
west of the Cascade range, but I never met with it; I 
should not say that it was by any means an abundant 
species. 
PurynosomA CornutumM. (Gray.) 
This species is much larger. than Tapaya Douglassii, 
and has a much more extensive geographic range. The 
specimens I brought home were obtained on the open 
sandy plains laying north of the Klamath lakes—these 
plains appear to be its limit north, beyond this Tapaya 
Douglassii replaces it—and also on the sunny hill sides 
at Colville. Whether it is to be found along the coast 
range, or west of the Cascade mountains, Iam not sure ; 
at any rate I never saw it there. Its colour very nearly 
approximates the basaltic piles, in the cracks of which 
it lives. 
Tapaya Dovetassu. (Girard.) 
The Oregon Horned Toad. 
I never saw this singular looking lizard on the west 
slope of the Cascades, but they abound on the sand
