ously striped, spotted, dotted or marbled with dark brown, 

 blue, green, gray or yellow. There often is a double series 

 of large brown spots, light-edged behind, along the back. 

 These usually are much more distinct in the females and 

 young than in adult males. The tail is similarly marked or 

 ringed with brown. The ground color below is yellowish 

 white, usually more or less tinged with greenish or bluish on 

 the sides of the belly. The throat in adults is blue, dotted or 

 narrowly banded on the chin and sides with white, yellow 

 or orange. There is a round spot of deep indigo behind the 

 axilla, and usually a brown patch in front of the shoulder.

Remarks. — What has been said under this heading in 

 writing of U. s. stansburiana may be applied here. These 

 lizards are very abundant. Large series could be collected 

 in many localities. If such a series were secured and thor- 

 oughly studied it is possible that interesting facts in varia- 

 tion and distribution might result. The amount of study 

 involved would be very great, and individual variation 

 might prevent any really satisfactory conclusions. 



As Richardson states, this subspecies resembles U. s. ele- 

 gans in size of body and in the character of the squamation, 

 but the dorsal scales are smaller. In other words, U. s. hes- 

 feris is similar to U. s. stansburiana, except that it has dorsal 

 scales more strongly keeled and changing less gradually to 

 the granular laterals. This difference is manifestly slight and
