186 MR. G. A. BOULENGER ON THE 
the species was established. I am therefore surprised to find my ZL. muralis, 
var. portschinskii, and my L. m. var. rudis, referred to by Méhely in his synonymies as 
L. muralis, var. depressa, as well as to miss all allusion to my identification of L. defilippii, 
which should have been quoted as L. muralis, var. defilippit. 
Remarks will be made further on concerning the names given by Méhely to the 
varieties here dealt with. . derjugini Nikolsky and Z. chlorogaster Boulenger (which 
name has priority over L. boettgeri Méhely) appear to me to be entitled to rank as 
species distinct from J. muralis. 
The forms dealt with here may be briefly defined as follows :— 
A. Var. chalybdea Eichw. Hind limb short, reaching the elbow or the axil in the male, not 
beyond the elbow in the female; foot not or but slightly longer than head. Granules 
between the supraoculars and the supraciliaries usually forming an incomplete series, some- 
times reduced to 8. Dorsal scales smooth, Jarger than tibials, 40 to 53 across middle of 
body. Femoral pores usually fewer than 20. 24 to 28 scales under the fourth toe. From 
snout to vent up to 75 mm. ‘Transcaucasia, Asia Minor, Mesopotamia. 
B. Var. saxicola Eversm. Wind limb longer, foot longer than head. Granules between supra- 
oculars and supraciliaries forming a complete series. Dorsal scales smooth, not larger than 
tibials, 50 to 65 across middle of body. Femoral pores 16 to 22. 25 to 31 scales under the 
fourth toe. From snout to vent up to 80 mm. Crimea, Cis- and Transcaucasia, Asia 
Minor. 
C. Var. portschinskii Kessl. Like the preceding, but smaller and more slender, with more pointed 
snout. Dorsal scales smooth, as large as or larger than tibials, 51 to 56 across middle of 
body. 26to 31 gular scales. Femoral pores 16 to 21. Not known to exceed 57 mm. 
from snout to vent. Transcaucasia. 
_— 
), Var. defilippit Camer. Proportions more as in the preceding. Dorsal scales smooth, as large 
as or larger than tibials, 46 to 53 across middle of body. Caudal scales usually feebly keeled. 
22 to 25 gular scales. Femoral pores 14 to 20. Size as in the preceding. Transcaucasia 
aud Northern Persia. 
). Var. rudis Bedr. Dorsal scales more or less distinctly keeled, 45 to 58 across middle of body ; 
tibial scales much larger, strongly keeled ; caudal scales almost spinose on the sides. 25 to 
34 gular scales. Femoral pores 15 to 23. From snout to vent up to 87 mm. Trans- 
caucasia. 
These varieties completely merge into one another, and the definitions are necessarily some- 
what vague and unsatisfactory. They might all be thrown together under the name of 
LL. chalybdea, which has priority over that of sazicola adopted by Méhely. Although 
L. chalybdea, iv this extended sense, might be regarded as sufficiently distinguished from 
the forms of ZL. muralis inhabiting South Eastern Europe to justify its recognition as a 
species, we must not lose sight of the state of things in South Western-Hurope, where the 
var. bocagii completely connects the typical L. muralis with a mountain form, var. monticola, 
which in all its characters closely approaches L. chalybdea. 
A fifth variety may be said to connect the var. dreviceps with L. derjugini :— 
F. Var. caucasica Méhely. Head not strongly depressed. Collar-edge more or less distinctly 
serrated. Dorsal scales smooth or faintly keeled, larger than tibials, about 40 to 50 across
