more or less in verticils ; scales on the cliin and throat minute, 

 as small as the bod3'-granules ; those of the belly larger than the 

 body-granules, but smaller than the scales on the upper surface 

 of the snout. 



Colour olive-grey ; the back and sides with rufous spots, 

 forming interrupted longitudinal lines, those on the back larger 

 than those on the sides and with a white hinder margin \ A 

 pale or light reddish band down the centre of the back. Some- 

 times a dark band from the nostril to the eye, and prolonged 

 along the temporal region. The sides generally black-spotted, 

 and the throat more or less marked with transverse, somewhat 

 wavy, black and white bars. 



This species is closely allied to P. Jlavipunctatus, Eiippell, but 

 is distinguished from it by its generally longer hind limbs, and by 

 the large and polygonal convex scales covering the snout. 



The lizards from Socotra which have been referred to this 

 species have a much more pointed and considerably longer snout 

 than the types, and from the pronounced character of this varia- 

 tion, they would seem to be entitled to rank as a subspecies. 

 The typical form of P. rupestris, Blanford, has hitherto been 

 recorded only from Kharij Island, in the Persian Gulf, near 

 Bushire, and from Maskat.

Head short and high ; forehead flat, or convex antero-poste- 

 riorly ; snout short, but longer than the distance between the 

 eye and the ear, sharply pointed, beak-like ; nostril perforated 

 in a single, prominent, rather swollen, crescentic shield, the 

 horns of the crescent either meeting behind the opening, or 

 separated by one or more head-granules ; occasionally, the nostril
