PEISTUEUS. 865 



sub-caudals Limbs moderate, granular above, with scattered enlarcred 

 tubercles, the granular scales larger and flatter below, on the thighs 

 especially. Toes and fingers rounded, rather short, and covered with 

 small imbricate scales above. Colour sandy with dark spots, taking 

 more or less the form of cross-bands on the back and tail. Dark 

 marks from the nostrils on each side through the eye, sometimes 

 meeting each other on the occiput. A dark interrupted line on each 

 Bide from behind the eye, along the side of the back. 



Eab.~M.r. Blanford says— "It abounds in parts of Beloochistan, 

 being found in houses and under stones on the hill sides." Specimens 

 were also collected in Sind by Mr. Blanford.

Plate 



Scales of the back, sides and upper part of head and limbs equal, 

 not imbricate, round, convex. Back not crested. Tail compressed later- 

 ally, indistinctly verticillate, with a low crest of flat spines, their points 

 directed a little backward along the top ; none below. Scales of the 

 sides of the tail equal, granular ; those below rather larger and flatter. 

 Scales of abdomen round, flat, a little larger than those on the back, 

 and passing so gradually into the convex scales of the sides, that it is 

 difiicult to estimate the number. No femoral or prae-anal pores. Pupil 

 round. Upper eyelid slightly developed; no lower eyelid. Nostril 

 directed laterally upwards between the rostral and about three scales, 

 two of which on each side of the nostril are enlarged, the outer of 

 these separating the nostril from the first labial; the other enlarged 

 scale does not meet the corresponding one on the opposite side of 

 the rostral. Eostral large, cleft above. Mental larger and broader 

 than the rostral. Upper labials 6. Lower labials 3. No enlarged 

 chin shields behind the labials. 



Limbs rather elongate, the fore limb laid forward reaches the end 

 of the nose, and laid back extends to the thigh ; the hind limb laid 

 forward comes nearly or quite to the ear. Toes 5-5, slender, rounded, 

 with minute claws. Scales above the limbs similar to those on the back, 

 those on the inner anterior side of thigh and below the tarsus larger 

 and flat, those above the toes imbricate. Beneath the toes there are 

 cross plates as in Gymnodactylus, scarcely so broad as the toes, the 

 plates beneath the joints of the toes being longer but not broader 

 than the others. 



Colour olive grey, a pale band down the centre of the back, the back 

 and sides with rufous spots, forming broken longitudinal lines, those on 

 the back larger than those on the sides, and with a white hinder margin. 

 These spots disappear in spirit. A narrow dark line from nostril to 

 the eye, continued a short distance behind the latter. Chin covered 

 with dark spots. 



Length. — 2 to 2'5 inches, of which the tail is 1'25 to 15.
