Amphisbana elegans, Gervais, Bull. Sci. Nat. de France, 1855, 

 p. 135 ; Mag. Zool. 1835, class 3. t. 1 1 (details not good). 



Hab. Tangier (Fraser, B.M. 1848); North Africa (B.M. 184G); 

 Algeria {Dumeril, B.M.). 



This animal was first described by Dr. Kaup, who showed that 

 the teeth of it were placed on the edge of the jaw, as in the genera 

 of the family Agamidce, which are all confined to the eastern he- 

 misphere and Australia ; while all the other genera of the order 

 that have been examined have the teeth on the inner side of the jaw, 

 as in the family Iguanidce, which is restricted to the New World. 



It was afterwards described by M. Gervais; and even when Dr. 

 Kaup had informed him, after inspecting the specimen, that it was 

 the same as he had previously described, he still regarded it as new, 

 because he said the skull did not agree with Dr. Kaup's figure: 

 but this was a mistake. Dr. Kaup figured the skull of Trogonophis 

 and of an Amphisbcena for the sake of showing the difference between 

 them ; and M. Gervais must have compared his animal with the 

 wrong figure.
