Uta stansburiana Baird & Girard. 
Sceloporus biseriatus Hallowell. 
Sceloporus orcutti Stejneger. 
Phrynosoma blainvillii Gray. 
Lampropeltis boylii Baird & Girard. 
Salvadora grahamie Baird & Girard.—A Salvadora 
whe here by Mr. Coolidge has 17 scale rows, gastrosteges 
199, urosteges 92, frontal short and broad, parietal short, ros- 
tral wide with detached edges, first pair of infralabials elon- 
gated posteriorly, mental small, and posterior genials separated 
by small scales. I have no specimen from Texas for compari- 
son. Ten from Lower California agree in the main with this 
one from Riverside but have rather larger rostrals and show 
that the shape of the frontal and parietal plates is inconstant. 
9. Arizona elegans Kennicott.—One specimen. 
10. Pituophis catenifer (Blainville)—One young gopher- 
snake, taken July 3, 1899, has four large and two small pre-
