142 ME. G. A. BOULENGER ON THE REPTILES 



C. sepoides occurs from Senegambia and Algeria to Egypt, Arabia, and Syria. Like 

 the true Scink, it is essentially a sand Lizard, adapted for burrowing. It is scarce in 

 Algeria and Tunisia. Gervais records it from the Souf and Strauch from the Mzab. 

 M. Lata&te received from Major Oudri a specimen from Mraia, and found a single one 

 himself at Tuggurt. He obtained anotlier specimen in Tunisia, at Mettamer, and records 

 it from Tozeur (collected by Dr. Andre).

 the extremity of the parietal crest ; a small but very distinct occipital dermal lobe on 

 each side, extending to the extremity of the parietal crest. Body uniformly granulate; 

 no dorsal crest ; a more or less distinct series of conical scales on the anterior part of 

 the vertebral keel ; a series of conical, slightly enlarged granules on the median line 

 of the throat ; no ventral crest. No tarsal process. Tail usually a, little shorter

The Chameleon inhabits North Africa, the South of Spain, Asia Minor, and Syria. 

 It is more or less common all over Barbary, where shrubs or trees occur, and it is also 

 found iu the oases of the Sahara. A good whole figure is given in the "Description de 

 I'Egypte," Rept. pi. iv. fig. 3 ; and of the liead in the British Museum Catalogue of 

 Lizards, iii. pi. xxxix. fig. 1. A specimen from Bou-Saada has recently been described 

 as C. saharicus by F. Miiller, Verb. nat. Ges. Basel, vii. 1885, p. 715, pi. .s.\., and viii, 

 1887, p. 295, but it is nothing but a half-grown C. vulgaris.
