Head-Shields as in the typical form of L. muralis, but frontal rather broader 
than usual; nasal forming a short suture with its fellow, and, in two specimens, 
in contact on one side with the anterior loreal; granules between the supraciliaries 
and the supraoculars reduced to 3 to 10; parietals as long as broad or but slightly 
longer; occipital smaller than the interparietal, entirely absent in one specimen; 
temporal scales usually larger than in the typical form, the masseteric plate destinet 
and in contact with the upper temporal or separated from it by one series of scales; 
four upper labials anterior to the subocular. Gular scales rather large (20 to 25 in 
a longitudinal series); gular fold rather feebly marked. Collar very feebly denticulate, 
with 8 to 10 plates. 
Scales on body rhomboidal or distinetly hexagonal, and more strongly keeled 
than usual in the typical form, 46 to 55 across the middie of the body, 3, or 2 
and 3 transverse series correspond to one ventral plate, 24 to 36 to the length of 
the head. Ventral plates in 6 longitudinal and 23 to 28 transverse series. 
Preanal plate large, bordered by one semicircle of small plates. 
Scales on the upper surface of the tibia keeled and much smaller than the dorsals 
22 to 24 lamellar scales under the fourth toe. 14 to 16 femoral pores on each side. 
Upper caudal scales strongly keeled aud more or less distinctly pointed behind, 
sometimes marly as much as in L. vivipara. 
The coloration is the same as in most examples of the typical form of L. mu- 
ralis, with a dark lateral band, light-edged above and beneath, and a dark vertebral 
streak or series of spots; these marking are strongly defined in the very young; 
the belly of the males is marked with thick black dots, and the throat and breast 
are spotted with black in both sexes. This type of markings, wich is frequent in the 
typical form of L. muralis, is also that which most nearly approaches the pattern 
of L. vivipara.

Prof. v. MineLy has recently (1) expressed the opinion that the Caucasian form 
L. sazicola is to be regarded as representing the ancestral stock out of which 
L. vivipara has been evolved. In my opinion, the variety here described establishes 
an even closer connection between the typical L. muralis and L. vivipara than is to be 
found in any of the Eastern forms yet described, including NiroLst's L. Derjugini (2), 
which is also intermediate betwen the two species. A much closer knowledge of the 
variations of these lizards than we now possess in required before we can profi- 
tably speculate on this question.
