bar of black just before the shoulder and behind the neck-fold; lower surface 

 yellowish or greenish, slightly iridescent; a black Y-shaped mark beginning 

 just behind the shoulders and extending to the vent; black continued on to 

 the ventral surfaces of the hind legs; an indistinct mottling of pale brown on 

 the throat; a suffusion of pink on the under surfaces of the tail. 



Measurements. — Total length, 231 mm.; head and body length, 74; fore leg 

 from axilla, 28; hind leg from vent, 46; greatest width of head, 12.5. 



Remarks. — Females differ from the males in having much more 

 conspicuous dorso-lateral stripes. These are continued forward 

 along the sides of the head. The black cross-bars on the back 

 are only irregularly formed in the female; they usually consist of 

 a series of spots. There is no conspicuous black pattern on the 

 ventral surface of the female. 



This species of Stenocercus which has very much the same form 

 as Leiocephalus, differs from that genus not only structurally 

 (absence of abdominal ribs), but also in habits. All the speci- 

 mens secured frequented stone-walls or stone piles and were 

 never seen among the ground litter or in open places as in the 

 case of Leiocephalus.
