Locerfn. 321 



30 to 42 (usually 33 to 37) scales and granules in a straight line 

 between the symphysis of the chin-shields and the median collar- 

 plate; gular fold very indistinct or totally absent; collar not 

 serrated, composed of 10 to 13 (exceptionally 8 or (3) small or very small 

 plates, which may be scarcely larger than the scales in front of them. 



Body covered with small fiat, roundish granules, which are a little 

 smaller on the sides than on the back ; 59 to 7t) (usuallv 63 to 70) 

 scales across the middle of the body, 3 or 4 (rarely 5) transverse 

 series corresponding to a ventral plate, 31 to 50 in the middle of the 

 back corresponding to the length of the head. 



Ventral plates in 6 (rarely 8) longitudinal and 25 to 30 transverse 

 series ; the plates of the 6 series sometimes subequal in width, some- 

 times unequal, those of the median row from the middle line the 

 broadest ; when in 8 series the plates of the outer row very narrow.* 

 Preanal plate moderate or rather small, bordered by one, or, more 

 usually, two series of small plates of which a median pair may be more 

 or less enlarged. 



Scales on 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. 19 to 25 femoral pores on each sidef ; 

 sometimes a second series of rudimentary pores.;]: 



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

 strongly but obtusely 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 broadest, in the basal 

 part, at least twice as broad as long ; i-egenerated tail sometimes with a 

 single series of large plate-like scales infei'iorly ; the whorls longer 

 and shorter alternately ; 18 to 30 scales in the fourth or fifth whorl 

 behind the post-anal granules. The sensory apical pits on the caudal 

 scales usually more distinct than in any other species of the L. muralis 

 group. 



Grey or bluish grey above § with a dark network enclosing very 

 numerous small roundish light spots, or with small ocellar markings 

 having a tendency to form transverse series ; upper surface of head 

 often with symmetrical blackish 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., L. toniasinii, 

 Schreib.) black or l)lackish brown, Avith more or less distinct paler 



* 8 rows in 5 out of 22^ specimens in the British Museum.
