762 ON A NEW SPECIES OF SCELOPORUS. [DeC. 19, 



cuspid, strongly keeled ; nine scales, taken in the middle of the back, 

 correspond to the distance from the end of the snout to the posterior 

 border of the occipital shield ; they are arranged in 42 to 44 trans- 

 verse series (from occipital shield to line of hinder side of thigh) and 

 1 1 longitudinal series (a line drawn on each side from the upper edge 

 of the ear-opening, and which corresponds in this species with the 

 outer border of the yellowish band, being taken as the boundary 

 between the dorsal and lateral scales) ; lateral scales smaller, tricuspid 

 and strongly keeled, directed upwards ; abdominal scales smooth, 

 distinctly bi- or tricuspid, two thirds the size of the dorsals. 

 Femoral pores 12 or 13 on each side. Limbs moderate; carried 

 forwards, the fore limb extends beyond the snout the length of 

 the claws of the longest fingers, the hind limb reaches the collar- 

 fold in the male, a little beyond axilla in the female. The female 

 exhibits the following coloration :— Upper surface of head, limbs, and 

 tail uniform light reddish brown ; a purpUsh-grey vertebral band, 

 ending at base of tail ; on each side two reddish-brown longitudinal 

 bands separated by a yellowish-white narrower band commencing 

 from the eye ; a second light band from axilla to groin ; more or less 

 obsolete blackish markings, obHquely directed backwards, across the 

 dark dorsal bands ; an obsolete blackish streak at base of humerus ; 

 lower surfaces yellowish white, immaculate. The male differs in 

 the following points : — the interval between the two yellowish-white 

 lateral bands darker, blackish : an intensely blaclc streak from collar- 

 fold to forearm ; a small greenish-blue spot on each side of the 

 throat, bordered anteriorly by a few greyish dots ; an elongate 

 iridescent greenish-blue black-margined spot on each side of the 

 belly, the white interspace between them being twice their width.
