166 ME. G, A. BOULENGEE ON THE 



(rarely five or three) ; temporal scales rather large, with a distinct masseteric disk, 

 which is sometimes in contact with the last or penultimate upper labial. 



Dorsal scales large, flattened, roundish-hexagonal or oval, smooth or faintly keeled, 

 rather smaller on the sides, where 3 or 4 correspond to a ventral shield ; 39 to 49 

 (usually 42 to 46) scales across the middle of the body; 22 to 31 scales, in the middle 

 of the back, correspond to the length of the head. 23 to 27 gular scales in a longi- 

 tudinal series; collar straight-edged, with 8 to 11 shields. Ventral shields in 6 

 longitudinal and 23 to 27 transverse series (23-25 in j , 25-27 in 2 ) ; anal large, 

 with a single semicircle of small shields. Scales on upper surface of tibia more or 

 less distinctly keeled, considerably smaller than dorsals. 16 to 23 femoral pores 

 (usually 16 to 18) on each side. 26 to 28 lamellae under the fourth toe. Caudal 

 scales truncate behind, more or less strongly keeled, often feebly keeled at the base of 

 the tail, in alternately longer and shorter whorls. 



Coloration of upper parts much as in L. muralis tyjnca, sometimes with greenish 

 gloss *. A vertebral series of dark dots is often present, sometimes forming a vertebral 

 streak ; lower parts pale yellow, sometimes washed with greenish, with or without 

 small black or rust-coloured spots on the sides of the belly, which are always devoid 

 of blue spots f . For fuller particulars of the coloration I refer to Prof. Mehely's 

 detailed description, from which I have drawn as regards the variations in the 

 lepidosis. The following is a tabulation of the numerical characters in the specimens

t As in some Caucasian specimens (var. chalyhdea) on which Mehely has founded his var. armeniea. These 

 blue spots are also absent in many females of other varieties, and, though rarely, in some males also. 



X If compared with the measurements of Bosnian specimens (above, p. 162), it will be seen that there is no 

 justification for Mehely's statement (1909, p. 600) " Gliedmassen etwas kiirzer " than in L. muralis.
