the surface of a small pond in the garden near Mr. MeFee’s house. 
They kept dipping down and touching the surface of the water 
as if drinking. The five specimens shot, and preserved as skins, 
were very fat. 
THE REPTILES. 
During each of the three summers constant lookout was main- 
tained for previously unnoted reptiles, and for items of interest 
in distribution and habits. Aside from the Pacific rattlesnake, 
garter snake, and mountain lizard, reptilian species were rare 
above the Upper Sonoran zone. But in that zone species and 
individuals were fairly numerous. Out of the twenty species 
recorded, four were found only in the Lower Sonoran zone on the 
desert base of the mountains, one was found only in the Tran- 
sition zone, and fifteen were found in the Upper Sonoran zone 
on the Pacifie side of the mountains, where most of our work 
was done. 
About 160 specimens were taken and these are now deposited 
in the reptile collection of the University of California Museum 
of Vertebrate Zoology. Most of them were captured by noosing. 
They were then put into a mixture of 4 per cent. formalin in 70 
per cent. alcohol, and after we got home transferred to 80 per 
cent. alcohol for permanent preservation. I found this treatment 
satisfactory in all cases. 
Crotaphytus baileyi Stejneger. Bailey Leopard Lizard. 
I ‘‘auxed’’ a specimen of this species at about 5000 feet al- 
titude in the canon between Cactus Flat and Cushenbury springs 
on the desert slope of the mountains, August 14, 1905. It is 
111% inches in length; the black transverse bands across the 
shoulders are unusually broad and distinet for the species, and 
the posterior one is continuous across the nape. 
Crotaphytus wislizenii Baird & Girard. Leopard Lizard. 
I shot one young specimen beneath a creosote bush on the 
desert near Cushenbury springs, August 14, 1905. No others 
were seen.
