tinguish it from tlie C. sexUneatus, while the six longitudinal stripes 

 on a (lark iirouiul have the same origins and terminations as in that 

 species. The only difference in the squaniatioii is seen in the presence 

 of one or two rows of large scutes on the posterior face of the forearm. 

 Accompanying this character is a larger number of femoral pores, which 

 range from eighteen to twenty-two, averaging about twenty, as against 

 sixteen and seventeen of the eastern form. Specimens having such 

 characters generally have a single series of light spots in the dark 

 spaces between the longitudinal stripes, which are not confluent with 

 the light stripes, and which do not therefore break up the dark stripes 

 into spots. The majority of such specimens have light spots on the 

 sides below the inferior stripe. In some smaller specimens, presuma- 

 bly females and young, all the spots are wanting. In this subspecies 

 the frenoocular jdate occasionally ai)pears. The general proportions are 

 as in C. s. se.vlineatiis, the longest toe of the extended hind leg reaching 

 to the front of the meatus auditorius. The size of adults exceeds a 

 little that of the eastern form, a specimen from Arizona (Cat. No. 5020) 

 measuring 100 mm. from the end of the snout to the vent. This is, 

 however, larger than the average. 



This form is found in western Texas, New Mexico, and Arizona, and 

 in Mexico as far south as Chihuahua and Monterey. 



Certain specimens agree in all respects with this subspecies, except 

 in the possession of a smaller number of femoral pores. Such are Cat. 

 Nos. 3055. 3022, 3000, 3010, 3071, 1871, and 9247. Cat. No. 3022 includes 

 five specimens, which present the typical characters of the subspecies, 

 but add a peculiarity, in which they all agree, namely, the possession 

 of six infralabial plates, thus approaching the C. grahamii. The males 

 have the thoratdc region black and the abdominal scales more or less 

 margined with the same color. The same color character appears in 

 a few other specimens, and in Cat. No. 15C04 there are six infralabials 

 on one side.
