Remarks. 



• Toung. 



As to the food of tliis species Dr. Stejueger remarks: 



The ferocity and greed of this species is well illustrated by several of the .speci- 

 mens caught. Thus the stomach of a young male (No. 18291) was found to contain 

 two full-grown lizards, Uia stanhitriana, while an adult female (No. 18276) whfen 

 opened gave up one full-grown horned toad, Phrynosoma platyrhinos, besides rem- 

 nants of a grown specimen of her own species. 



The habits of Crotaphytus wislizenii are giveu by Dr. Merriam' as 

 follows : 



The leopard lizard is abundant in most, if not all, of the Lower Sonorau deserts 

 of the Great Basin, from southern California eastward across southern Nevada to 

 Arizona and southAvestorn ITtah. While properly belonging to the lower Sonoran 

 zone, it ranges up a, certain distance into the Upper Sonoran, occurring farther 

 north and higher on the mountain sides than eitlier CalUsaurua or DipsoauMvus, and 

 usually a little higher even than Cnemidophorus. 



It was found in abundance in all of the Lower Sonoran deserts traversed, from the 

 Mohave Desert, Panamint and Death valleys, Ash Meadows, the Amargosa Desert, 

 Indian Spring, Pahrump, and Vegas valleys to the Great Bend of the Colorado, and 

 thence northerly through the valleys of the Virgin and Muddy, across the north- 

 west corner of Arizona to the Santa Clara Valley in Utah, and Pahranagat and 

 Meadow Creek valleys in Nevada. The upper limit of its range was not reached except 

 in a few places, as indicated by the following localities. It was abundant through 

 Antelope Valley, at the extreme west end of the Mohave Desert, ranging thence 

 northerly through the wash or open canyon leading to Tchachapi Valley. (It was 

 not seen in Tehachapi Valley, which is not strange, as a sharp, cold wind blew the 

 only day we were there.) It ranges completely over Walker Pass (altitude of divide 

 1, 550 meters, or 5,100 feet) and is common in Owens Valley, ranging as far north at 

 least as Bishop Creek, and as high as 1,980 meters (6,500 feet) along the west slope 

 of the White and Inyo mountains (opposite Big Pine). On the east side of the White 

 Mountains it is common in Deep Spring and Fish Lake valleys, and was found on the 



' North American Fauna, No. 7, 1893, p. 167.
