ALLIED TO LACERTA MURALIS. 77 



Scales (11 upper surface of tibia obtusely keeled, as large as or a little larger or a 

 little smaller than largest dorsals. 22 to 26 lamellar scales under the fourth toe. 

 I'.' to 23 femoral pores on eacli side*; sometimes a second series of rudimentary 

 pores f . 



Caudal scales truncate, oblique, the upper smooth or more or less strongly, but 

 ()t)tuscly and diagonally keeled, the lower smooth ; the median dorsal pair sometimes 

 a little larger than those adjacent to it, the median ventral pair strongly enlarged, the 

 largest at least twice as broad as long ; regenerated tail sometimes with a single scries 

 of large plate-like scales inferiorly ; the whorls longer and shorter alternately ; 18 to 

 oO scales in the fourth or fifth whorl behind the postanal granules. The sensory 

 ajjical pits on the caudal scales usujljly more distinct than in any other species of the 

 L. muralis group. 



Grey or bluish grey above [J; with a dark network enclosing very numerous, small, 

 roundish, light spots or with small ocellar markings having a tendency to form trans- 

 verse series (PI. VI. fig. 1); upper surface of lieud often with symmetrical blackisli 

 markings and dark edges to the shields ; lower parts greyish white or bluish grey ; 

 tail more bluish, with regular black annuli, which are interrupted inferiorly. Young 

 like the adult. Some specimens (var. atra Bedr., tomasinii Schreib.) black or 

 blackish brown (PI. VI. fig. 2), with more or less distinct paler brown spots ^, dark 

 "ley or blue beneath.

i Sometimes brownish, yellowish, or •jroeiiish, according to Schreiber. 



§ After some time in spirit, these liglit spots become more distinct and certain preserved specimens may 

 be 8uid to be absolutely intermediate between the typical form and the black variety. Werner (1907) alludes 

 to specimens from a great altitude in Herzegovina as only '' ziomlich dunkel.'' The supposed structural 

 diti'crenccs between the two forms, pointed out by Muhcly, have no existence in fact.
