No. 34198, was taken in Ventana Canyon, Catalina Mountains, 
April 28, 1912. Eleven (Nos. 34283 to 34293) were collected 
near the steam pump in the foothills of the Catalina Moun- 
tains, eighteen miles north of Tucson, May, 1912. No. 35000 
was caught in Ramsey Canyon, Huachuca Mts., July 27, 1912.

Valley, Maricopa Co., May 1910. No. 13169 is labeled merely

Helodermas were found out at any time of day. They were 
found in the giant cactus, creosote bush, and oak belts. All 
found were merely walking about. They hasten their gait 
when one approaches them, but were never seen to run. Two 
put ina pillow case and hung ina tree, scratched a hole through 
the cloth and escaped. The species still is common in favorable 
locations.

We have five specimens of this handsome lizard (Nos. 34962 
to 34966) secured in Ramsey and Carr Canyon in the 
Huachuca Mountains, Cochise County, July 3 to 29, 1912. 
They were found in the oak belt, on the ground among stones 
~ and dead ieaves, walking about in the day time, and were very 
shy. All five have fourteen longitudinal rows of dorsal scales, 
of which three rows on each side of the middorsal line are 
weakly keeled except in No. 34963, which has four keeled rows 
on each side. The dorsal scales in a row from the interoccip- 
ital plate to the backs of the thighs are 45, 48, RO, Sule 5250 Oia 
the belly one counts in a row from the mental plate to the anus

body, while one has nine and one eleven. The dark bands on 
the tail vary in number from fourteen to nineteen.
