of the neck, enclosing short longitudinal folds. The prominent por- 

 tions of these folds bear patches of more or less spiny tubercles. 



Olive above, marbled on the sides and back by about eight nar- 

 row, transverse, black bands, which scarcely meet in the vertebral 

 line, and enclosing pale whitish round spots. Tail pale yellowish 

 olive above, with narrow dark olive-brown bands that do not extend 

 to the under surface. Throat yellow, finely marbled with narrow 

 reticulate dark-olive lines. Under surface of belly, limbs, and tail 

 yellowish. 



Length: snout to vent l£§", vent to tip of tail 2f|", snout to 

 occiput 6'", fore limb 1" 1'", hind limb 1" 8'".

A closely allied species to this is the S. himalayensis, Steind., 

 from which the present specimen is distinguished by the abrupt 

 separation of its enlarged dorsal scales from the lateral granules, 

 which in S. himalayensis, now before me, pass gradually one into 

 the other — and by the presence of the tubercular keeled area on its 

 sides, which does not exist in the allied species. There are othe* 

 points of difference ; but these are among the most prominent, com- 

 bined with the difference in coloration. 



Agama agilis, Olivier. 



I can add nothing to the characteristic description given of this 

 Lizard by Dumeril and Bibron, except as far as regards a point in 

 coloration. In the four specimens before me, of all ages, not only 

 the throat but the belly has longitudinal dark lines, which, however, 

 are more indistinct on the latter than on the former. In one 

 adult, the greater part of the throat, and the sides, and under sur- 

 face of the neck and the sides of the belly are deep purplish black. 

 All have a deep spot of a similar colour on the side of the neck 

 before the shoulder. 



Hab. Shiraz. 



Length : snout to vent 3" 6", vent to tip of tail 4" 8'", head 11'", 

 fore limb 1" 11'", hind limb 2" 6'". 



This Lizard is recorded by Blyth from the Salt range of the Pun- 

 jab, but not included by Giinther in his • Reptiles of British India.' 

 Filippi describes a new species, A. lessonce, from Ispahan. 



Trapelus ruderatus, Olivier. 



Scales of different sizes, more or less feebly keeled, with numerous 

 large, rather erect, spiny, tubercular scales scattered over the body, 

 either singly or in groups, more numerous in the males than in the 

 females ; some of them, instead of being spinose, are only thickened 

 posteriorly ; they pass on to the root of the tail, but not beyond it. 

 Tail a little less than twice the length of the body and head, covered 

 with rhomboidal keeled scales, dilated at its base in the male, and 

 tapering. A fold across the neck, another from the lower angle of 

 the jaw, over the shoulder. A central group of large tubercular 

 furrowed shields on the frontal region, surrounded by slightly smaller 

 ones of the same character ; a group of similar shields on the occiput,
