posteriorly with white, gray, or yellow. There is an in- 

 distinct large dark blotch on each side of the neck. The 

 coloring of the tail is similar to that of the back. The 

 ground color of the head is very variable, as are also its 

 darker markings. The entire lower surface is white or 

 pale yellow, sometimes faintly marked with gray or 

 slate.

Distribution. Washington, Oregon, and Idaho con- 

 tain the greater part of the range of this lizard. Mr. 

 Chas. H. Townsend has recorded it from the northern 

 base of Mount Shasta, California, which is, I believe, 

 the only definite locality at which the Pigmy Horned 

 Toad has been found in this State, although it probably 

 occurs in many parts of Siskiyou and Modoc Counties. 



It has been recorded from Fort Steilacoom, Fort Walla 

 Walla, and North Yakima, Washington; from Grant's, 

 Des Chutes River, Willamette Valley, and between 

 Warner's and Goose Lakes, Oregon; and from Blackfoot, 

 Big Butte, Big Lost River, Pocatello, vie. Lewiston, 

 Conant, Arco, and American Falls, Idaho.
