rufous and have brown centers. Scales on the sides of the tail are opa- 

 line green. The general color of the upper parts and the top of the head 

 is deep olive buff to buffy brown. The scales of the dorsal surface are 

 edged with dark brown. The ground color of the ventral surface is 

 whitish. 



Tlie ventral patches are in three specimens divided and in one 

 united. There are no indications of dorsal cross bands or spotting in 

 any of the males. The female is marked dorsally with sixteen brown 

 patches, about a scale in width. The lower surface is creamy white 

 lightly tinted on scattered scales with pale greenish, pale orange and, 

 beneath the throat, pale blue. The collar of the female is brown. 



The largest male measures 266 millimeters and the tail length in 

 the same specimen is 149 millimeters. 



The rough-scaled lizard was only occasionally seen in the Turtle 

 Mountain region. It lives in and beneath catclaw bushes, on boulders 

 in the canon bottoms, and in caves in the undercut wash-banks. In 

 only one instance were any of these lizards noticed far from safe re- 

 treats. During the forenoon of June 2, while the ground was still 

 damp from a recent thunderstorm, two large male rough-scaled lizards 

 appeared at intervals on a bare hillside. An explanation of their un- 

 wonted fearlessness may have been that they were in an active sexual 

 state. 



A large orthopterous insect, somewhat chewed, a fly, a beetle, and 

 several other insects were found in one stomach. Another stomach 

 contained a grasshopper, a beetle, a lepidopterous insect, several small 

 red ants, and some pebbles. A third contained a caterpillar, five 

 Coleoptera, one hemipter, three small red ants, the fruit and green 

 leaves of a small plant (identity uncertain) and a few dry leaves (per- 

 haps taken accidentally). 



Phrynosoma platyrhinos Girard 

 Desert Horned-toad 



Five specimens of this species (nos. 5494-5498) were collected, in- 

 cluding two females and three males ; and these were all the horned- 

 toads seen in the Turtle Mountain vicinity. The males can be dis- 

 tinguished at once by the large postanal plates. The ear opening is 

 covered in all the above specimens. The femoral pores number 7 in 

 three thighs, 8 in five and 9 in two ; being J 1 9 right : 8 left once, 2 8 :9, 

 J 1 8 :8, £ 7 :8, 2 7 :7. The red of the dorsal parts varies much among in-
