170 MR. G. A. BOULENGEE ON THE 



to 53) scales across the middle of the body ; 3, or 2 and 3 transverse series of scales 

 correspond to one ventral plate, 31 to 45 to the length of the head. Ventral plates 

 in 6 longitudinal and 25 to 31 transverse series. Anal plate moderately large or 

 rather small, whh two semicircles of small plates ; an enlarged median plate sometimes 

 preceding the anal. 



Scales on upper surface of tibia considerably smaller than the dorsals, always 

 distinctly keeled. 22 to 29 (usually 24 to 27} lamellar scales under the fourth toe. 

 16 to 24 femoral pores on each side (usually 19 to 22). 



Upper caudal scales strongly keeled and obtusely but distinctly pointed behind ; the 

 scales more or less oblique * with the keel parallel to the axis of the tail ; the whorls 

 more or less distinctly longer and shorter alternately; 28 to 32 scales in the fourth 

 whorl behind the post-anal granules. 



This lizard shows much variation in the coloration, and some of the colour-varieties 

 appear to be fixed in certain localities. 



A. Green or olive-brown above, with brown vertebral and lateral bands spotted with 

 black ; six light pale green or white streaks, viz., on each side, one bordering the 

 vertebral band, one from the supraciliary border to the tail, along which it extends for 

 some distance, and one from below the eye to the side of the tail, passing through 

 the ear, above the fore limb, and through the hind limb. Lower parts white, 

 unspotted, or with a series of black dots on the outer row of ventrals. Specimens thus 

 coloured (var. striata Werner) are hardly distinguishable from the var. campestris, but, 

 according to Werner the head is, as a rule, more depressed (" eher platy- als pyramido- 

 cepbal "). The young is olive-brown, with six very sharply defined white lines. Most 

 of the specimens referable to Werner's var. striata are females (PI. XIX. fig. 3), 

 but some males agree with it, at least in having the six light lines (PI. XIX. 

 fig. 4). 



Specimens from Bosnia and Herzegovina are in the British Museum Collection. 

 The types of var. striata are from Fiume, Spalato, Ragusa, Bol, and Gelsa. Strongly 

 striated specimens from Northern Greece have been named var. livadiaca by Werner. 



B. Specimens in which the back is green (olive-green to bluish-green) with black 

 spots as in the preceding, but the white lines reduced to the dorsal-lateral, have been 

 named var. fiumana by Werner (PL XIX. figs. 1 & 2). They are mostly males, with 

 bright orange-red belly and blue spots on the outer ventral shields. From Fiume, 

 Cherso, Veglia, Bragga, Lesina. Specimens from the Karst (Schreiber) are in the 

 Lataste Collection. Specimens from Bosnia and Herzegovina, associated with the 



* As in var. campestris. Count Peracca has pointed out to me that the scales in the anterior third of the 

 tail of var. campestris are less ohlique than in the f. tyjiica, and more so than in the var. serjpa, but he admits 

 it is very difficult to draw up any absolute definition of these different types of caudal scales. That the 

 character does not hold good in the typical form is well shown by the series at my disposal from Belgium, 

 where surely only one form of L. muralis exists.
