170 MR. G. A. BOULENGER 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, with 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- 
cephal”). ‘The young is olive-brown, with six very sharply defined white lines. Most 
of the specimens referable to Werner’s var. striata are females (Pl. XIX. fig. 3), 
but some males agree with it, at least in having the six light lines (Pl. 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. fiwmana 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 oblique than in the f. typica, and more so than in the var. serpa, 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.
