In its short and convex head, in its feebly serrated collar, in its pointed caudal 
scales, as well as its larger temporal scales, the var. dreviceps not only approaches 
L. vivipara, but also fills up to some extent the gap separating the typical LZ. muralis 
from the var. fiwmana.

Of this form, from the Mountains of Croatia, four examples are preserved in the 
British Museum :—

Habit rather stout and depressed. Head much flattened, with short, obtuse snout. 
The hind limb, stretched forwards, reaches the axil or the shoulder in the male, the 
wrist or the elbow of the adpressed fore limb in the female ; foot as long as or a little 
longer than the head. 
The rostral does not touch the nostril, and forms a suture with the frontonasal ; 
frontal short, usually as long as its distance from the rostral, sometimes as long as its 
distance from the end of the snout; a series of granules between the supraoculars and 
the supraciliaries, sometimes complete, rarely reduced to 5, the first and second 
supraciliaries being in contact with the supraocular * ; parietal more or less distinctly 
emarginate on the outer border, where it forms a suture with a large anterior supra- 
temporal, and usually in contact with the upper postocular ; occipital usually shorter 
and narrower than the interparietal, sometimes extremely small. A single postnasal ; 
anterior nasal often in contact with the anterior loreal + ; four anterior upper labials 
* In his original description (1904, p. 366) Méhely regarded ‘the complete series of granules as “ ein 
hervorragender Character” for the distinction of Z. horvathi from L. muralis. See also my remarks under 
Forma typica, pp. 139, 143. 
+ As frequently happens in French specimens of ZL. muralis (see Tr. 1905, p. 354, and also above, p. 140).
