CROCODILIANS, LIZARDS, AND SNAKES. 307 Above (lark green, with two dorsal series of cresceiitic dusky blotches, bordered by light blue dots, the blotches sometimes obscure and the blue dots irregularly scattered and mixed with black ones. Two light stripes on each side the neck and body, sometimes broken up into rounded spots, the lower especially where they are often elongated, forming transverse bars. The interspace of these are light lines, some- times plain dusky, sometimes spotted with black and light blue. Beneath, greenish white; sides of jaws and the chin banded with blue. A round black spot on the anterior third of the side, sometimes encir- cled by yellowish; a second spot sometimes on the side of the neck. Female with the lateral spot less distinct. The general appearance of the typical Utas is that of the Scelopori with small scales, but easily distinguished at the first glance by a well-. Fig. 38. Uta stansbuhiana Baird and Girakd. X 2 Between Kogales and Rio Grande. Cat. No. 9571, marked gular fold. This is very closely pressed to the subjacent skin, the internal surface lined with very small scales. On the edge of the fold a single series of about fourteen scales considerably larger than those immediately before them or on those on the breast, about equal. There arc slight indications of one or two constrictions anterior to the first, but they do not form regular folds, and there is no marked difference in the size of the scales. There is also a lateral fold or cavity on each side of the neck, lined with smaller scales, as in Sceloporus, but less dis- tinct. The dorsal scales are tubercular or granular, subliexagonal, becoming gradually smaller on the sides; abruptly much smaller in the groin. They are without spines above, and barely imbricated. On the sides they are plain tubercular and
