140 ME. G. A. BOITLEXGER ON THE EEPTILES 



15 times in the distance from snout to vent. Bronzy olive above, uniform or with nine 

 or eleven dark brown longitudinal streaks, as broad as or broader than the interspaces 

 between them, which occupy the middle of each scale. 



From snout to vent 126 millim., tail 134. 



C. Imeatus inhabits the south of France, Liguria, the Iberian Peninsula, Morocco 

 (whence I have received three specimens from M. H. Vaucher), and Algeria. Whether 

 the specimen of " Seps chalcides " from Casablanca, recorded by Dr. Boettger, belongs 

 to this or the following species, is unknown ; but Dr. Boettger kindly informs me that 

 a second specimen from Casablanca recently examined by him belongs to C. Uneatiis. 

 The only Algerian specimen 1 have seen is one obtained by M. Lataste at El Guerra, 

 and now in the collection of Dr. J. de Bedriaga. It is uniform olive above, and has 

 26 scales round the middle of the body; its length from snout to vent is 14U millim., 

 tail 92, fore limb 10, hind limb 12. 



3. Chalcides tridactylus, Laurenti, 1768. 

 Seps chalcides, Guichenot, Straucli. 



Very closely, allied to the preceding. Limbs weaker still, the hind one usually 

 shorter than the distance between the ear and the fore limb, and contained 15 to 24 

 times in the length from snout to. vent; third toe shorter than second. Olive or 

 bronzy above, uniform or with darker and lighter longitudinal streaks, which are 

 constantly in even number. 



From snout to vent 183 millim., tail 200. 



Inhabits Italy, Sardinia, Sicily, Tunis, and Algeria. Gasco records it from Egypt 

 (Alexandria). M. Lataste found it in Algeria at Oran, Bona, Aumale, between Azesga 

 and Tifrit, and between Bou-Saada and Biskra, and received it from Maison-Carree and 

 the Plateau of Sersou. Strauch mentions it from the Mzab. M. Lataste states in 

 his notes that specimens of this species were obtained near Tunis by M. M. Sedillot 

 in 1883. 



Well figured in Bonaparte's ' Fauna Italica.' 



4. Chalcides mionecton', Boettger, 1873. 



Snout rather conical than wedged-shaped, but with distinctly projecting labial edge ; 

 ear-opening not or scarcely larger than the nostril, on a line with the mouth. Nostril 

 pierced entirely in advance of the suture between the rostral and the first labial; supra- 

 nasals distinct or united ; frontal longer than broad ; fifth labial entering the orbit. 

 Body much elongate ; sides of body not distinctly angular, although somewhat more 

 so than in the preceding species ; 24, rarely 26, scales round the middle of the body. 

 Limbs short, tetradactyle, rarely with a rudimentary fifth digit: the length of the hind 

 limb equals or a little exceeds the distance between the anterior border of the orbit 

 and the fore limb; the length of the latter equals about three -fourths its distance
