LACERTA CHSARIS. 
Abstract P. Z.8. 1914, p. 41 (May 26th). 
Physiognomy and general proportions of Lacerta galloti, but 
much smaller and, from a phyletic point of view, of a more 
primitive pattern of coloration. 
Head rather large, difference in size according to sexes not so 
marked as in Z. galloti and its larger allies. Length of head 
1 of length to vent in the male, very little less in the female. 
‘he cheeks not noticeably swollen in the male. Width of head 
+ of the length, depth 3, width of pileus 4 in both sexes. Snout 
as long as the postocular part of head (to posterior border of 
tympanum) in the female, slightly longer in the male. 
Weck distinctly narrowed. ody slightly flattened. 
Tail long, more than two-thirds total length. 
Limbs elongate, the fore limb im both sexes reaching the 
nostril, the hind limb reaching the collar or not quite so far in 
the female, a little beyond in the male. 
Rostral usually touching the nostril {, separated from the 
frontonasal. 
Frontonasal as long as broad or slightly longer. 
Frontal a little shorter than its distance from the end of the 
snout in the female, but slightly in the male; twice as long as 
broad (on its narrowest point) in the female, slightly longer in 
the male; not touching the first supraocular. 
Supraoculars separated from superciliaries by a series of 
granules. 
Parietals as long as, or slightly longer, rarely shorter § than 
the frontal in the male, usually a little longer in the female, 
strongly bent down on the temple, occupying the place usually 
held by the supratemporals ||. 
Occipital at least as broad as the interparietal, usually con- 
siderably broader, and constantly broader than long; on an 
average larger in the male than in the female 4. 
Asingle postnasal. 5 upper labials anterior to the subocular **. 
* [The complete account of the new species described in this communication 
appears here, but since the name and a preliminary diagnosis were published in the 
‘Abstract,’ No. 134, 1914, the species is distinguished by being underlined.-—
