80 BAKBOUR — REPTILES FROM SINAI AND SYRIA [^'VoLV^' 



Stenodadylus guttatus seems to be the only species of this genus which 

 has hitherto been recorded from the region of Palestine and Sinai. It is, 

 however, but distantly related to the present form, which differs in having 

 smaller or more granule-like scales on the head and tail, much longer 

 limbs, and a different arrangement of the scutes about the nostril. ^ 



Head large, rounded; snout rounded, one-and-one-third times diameter 

 of the orbit, as long as the distance between the eye and the ear opening; 

 eye very large; ear opening oval, vertical, very small. Body elongate, 

 rather depressed. Limbs very long and slender, the length of the hind 

 limb but little less than the distance from the vent to a line connecting 

 the ear openings; digits elongate, rounded, feebly denticulated laterally; 

 head covered with small, pavement-like, hexagonal scales, each of which 

 has a granulate but not a keeled surface; rostral twice as broad as high, 

 with a mesial cleft through its entire height; nostril pierced in the middle 

 of a slight swelling between three nasals which siu-round it completely; 

 12 upper, 13 lower, labials; mental squarish; no chin shields. Body 

 covered with small, flat, pavement-like scales, belly scales smaller and more 

 irregular in shape than the dorsals, and also unkeeled. Tail cylindrical, 

 extremely slender (at the middle point of its length less than one half the 

 diameter of the tail of guttatus), covered with extremely minute, granular 

 scales. Color in alcohol, grayish white, with a few brown spots upon the 

 head and scattered, dark brown, wavy markings on the back, which tend to 

 form irregular cross-bars on the dorsal region and a coarse network on the 

 flanks. 



In habit S. elimensis recalls at once the description of S. willcin- 

 sonii (Gray) from Egypt, but this species is said to have the snout 

 acutely pointed, the scales subimbricate, and the nostril pierced 

 in a very strong swelling between the first labial and three nasals. 

 The head of this species, which Boulenger has figured (Cat. Liz. 

 Brit. Mus. I, 1885, pi. 3, fig. 3), shows a very different lizard. 



Ptyodactylus lobatus (Geoff roy). 



Under this general name several distinct geographic races of 

 closely related geckos have been confounded. Thus Boulenger 

 (Cat. Liz. Brit. Mus., I, 1885, p. 110) says, in beginning his de- 

 scription, " general proportions varying considerably." This is 

 certainly true; but I find upon examining the specimens in the
