236 BULLETIN 17 7, UNITED STATES NATIONAL MUSEUM 



The coloration of a young lizard only 31 mm. in length from snout 

 to vent is as follows: Body color pale olive-buff; a sepia lateral stripe 

 originating quite definitely just behind the eye and continuing over 

 the ear and along the body and fading out on the tail; above and be- 

 low, this sepia stripe bordered by a wide light stripe; faint traces of 

 the ends of dark cross bars on the back, appearing as about a dozen 

 dark irregular spots in a longitudinal row above the dorsolateral light 

 stripe; a narrow dark lateroventral stripe; belly immaculate; throat 

 and chest with about seven or eight transverse rows of large black 

 spots extending up onto the sides of the neck and lips; mental and 

 rostral shields conspicuously light and immaculate; top of head 

 unmarked excepting for some minute sepia dots at the junctions of the 

 head plates; two conspicuous white bars leaving the superciliary 

 border and crossing the eyelid, with a brown bar between them, which 

 is a continuation of one of the transverse rows of throat spots; arms 

 and legs faintly marked with sepia above. The adult coloration is 

 very similar although dulled. The throat of adult males is clouded 

 with gray, through which the cross banding of spots can usually be 

 made out. The pattern of stripes instead of bars in the young suggests 

 a connection with semilineatus, in which the striped pattern pre- 

 dominates even in the young.
