scales on the first fourth of the tail smooth, arranged in transverse 

 rows, more or less keeled on the remaining three fourths, forming 

 three longitudinal ridges on the under surface. Ventrals of mo- 

 derate size, smooth. Head covered on the mesial line with flat, 

 non-tuberculated scales larger than the others ; a large oval one oc- 

 cupying the centre of the occiput, with a tumid centre. Nasals 

 separated by three scales one above the other, and a lateral scale on 

 either side of the inferior one. Upper labials 31, increasing in size 

 towards the angle of the mouth, where the largest occurs. The two 

 corresponding to the rostral are more transversely elongated than 

 the others, which are immediately behind, and which are square, 

 rather rounded at their free extremities. Lower labials 26 ; a lon- 

 gitudinal line of five enlarged scales behind the mental on each side, 

 separated from the labials by a line of smaller scales. Upper eyelid 

 with a fringe of ten oblong scales ; lower eyelid margined with ten 

 long, pointed scales. Upper jaw with 10 teeth on either side, the 

 anterior two separated by a considerable interval ; 20 in the lower. 

 The teeth gradually decrease in size from behind forwards, showing 

 no indication of differentiation into incisors or canines. The nails 

 are yellowish, long, and pointed. The tail is long and prehensile, 

 exceeding the length of the body by half. Pale yellowish brown ; the 

 head pencilled with dark brown and pale yellow ; three short, dark- 

 brown longitudinal lines on the nape. Labials minutely punctulated 

 with brownish. The back and sides and upper surface of the limbs 

 with moderate-sized dark-brown spots, and small brown dots of 

 the same colour, with numerous yellow spots either involving one or 

 three scales. Four brown spots, in transverse series, between the 

 thighs. The base of the tail with two transverse brown bands, with 

 a very faint one between them ; the rest of the tail with blackish 

 spots along its sides, almost forming rings, but interrupted on the 

 upper surface by small yellow spots nearly constituting a longitu- 

 dinal line. The last fourth entirely black, separated by a yellow 

 band from a black ring anteriorly. The under surface on the an- 

 terior half is rich orange-yellow. Ventral surface generally yellowish 

 white.

This species is distinguished from P. caudivohulus by its smooth 

 scales and peculiar coloration, and by the number of its teeth. 



Phrynocephalus forsythh, n. s. (Fig. 7.) 



Scales small, granular, ovally rhomboidal or quadrangular, smooth, 

 arranged more or less in transverse rows, with a very few enlarged 

 white scales occurring at intervals. No tubercles. Two enlarged 

 scales on each side of the occiput, with a rather large tumid one in 

 the mesial line before them, with those on the vertex only slightly 

 larger than the ones external to them. Superciliary scales small. 

 Scales of the lower eyelid forming a moderately pronounced fringe 

 of ten scales with rounded points. Ear hidden. Nostrils anterior,
