overlooked the original description of Hichwald, which is based on a specimen from 
the Caucasus (‘habitat in Iberia, Somchetia”’), not from Tiflis as assumed by Méhely. 
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 :—

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. 
Form rather stout, head and body much flattened; limbs short, the hind limb 
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 
centre or the posterior border of the eye and the anterior border of the tympanum ; 
snout obtusely pointed. 
Rostral 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 
distance from the end of snout; series of granules between the supraoculars and the 
supraciliaries usually incomplete (3 to 8) +; interparietal long and narrow, much 
narrower than the short occipital; parietal usually more or less distinctly emarginate 
* In 4 out of the 16 specimens examined. 
+ Complete in a male from Mesopotamia, and in a female from Lake Van. In a female from Mesopotamia, 
the suture between the first and second supraciliaries is distinctly oblique.
