21, 1905, contained two chipmunks (Lutamias speciosus) tandem- 
ly aligned in the alimentary canal, nearer the cloacal opening 
of the snake than the mouth. The most posteriorly located chip- 
munk was approaching complete dissolution, much of the hair 
and bones, even, having disappeared. Another rattler, only 26 
inches long, taken on the upper Santa Ana June 20, 1907, con- 
tained a 108¢-inch alligator lizard (Gerrhonotus scincicauda), 
extended straight out in the snake’s alimentary canal. As is 
always the case, and of obvious necessity, the lizard had been 
swallowed head first. 
Crotalus mitchellii (Cope). Pallid Rattlesnake. 
This pale copper-colored species was detected only at Cushen- 
bury springs, 4000 feet altitude, which is in the Lower Sonoran 
zone at the desert base of the mountains. There we saw several, 
and two specimens were obtained. One was 35 inches in length 
and the other 39 inches. One of these was encountered at very 
close range in the evening (August 10, 1905) as I was setting a 
mouse trap beneath a bush out on the desert ; and the sudden buzz 
and rapidly coiling snake, barely discernible in the dusk within 
arm’s leneth as I knelt on the ground, was, to say the least, 
startling. Others were seen early in the morning; the species 
seemed to be inactive during the hottest part of the day.
