with a feeble straight keel * or even almost without a trace of a keelf . In a male from 

 Kakos, Hungary, which has very strongly keeled dorsal scales, and in another from 

 Corfu, the scales on the flanks, right down to the ventral plates, show a feeble yet 

 distinct keel. The number of scales across the body varies from 42 to 61 J ; on the 

 flanks, 3 or alternately 2 and 3 series of scales correspond to a ventral plate ; 36 to 50 

 scales, in the middle of the back, correspond to the length of the head. Ventral plates 

 in 6, exceptionally 8 §, longitudinal and 25 to 32 transverse series (25 to 29 in males, 

 25 to 32 in females) ; the plates-of the second series from the median line usually much 

 broader than the others. 



Praeanal plate moderately large or rather small, with 2 or 3 semicircles of small 

 plates or scales, one or two of the median plates of the inner semicircle sometimes 

 considerably enlarged.

J 42 is exceptional and occurs only in one female from L. Stymphalos, two males from the same locality 

 having 50 and 55 respectively. 48 to 55 is the usual number in the typical form, 52 to 60 in the var. ionica.
