ME. G. A. BOULENGEE ON THE 



overlooked the original description of Eichwald, which is based on a specimen from 

 the Caucasus ("habitat in Iberia, Somchetia"), not from Tiflis as assumed by Mehely. 

 The allusion to a " collare dentatum " in the original description is not against an 

 identification with the L. Gokscha specimens, as one of these has the collar feebly 

 but distinctly dentate. 



The following description is taken from sixteen specimens, particulars of which are 

 first given : — 



lelenovka, L. Gokscha 



Kavkaz, 



Van, Kurdistan 



Mesopotamia 



Bithynian Olympus

Hsr. 



The third specimen on this list is preserved in the Lataste Collection, and was 

 received from Dr. de Bedriaga. Two of the Mesopotamian specimens and two from 

 Lake Van (Mission Chantre, 1881) are preserved in the Lyons Museum.

 reaching the axil or the elbow of the adpressed fore limb in the male, the wrist or the 

 elbow in the female ; foot not or but slightly longer than the head. Head flat above, 

 nearly once and a half as long as broad, its depth equalling the distance between the

 snout obtusely pointed. 



Eostral not entering the nostril ; suture between the nasals very short, or * rostral 

 forming a suture with the frontonasal ; a single postnasal ; frontal as long as its
