414 MR. G. A. BOULENGER ON THE VARIETIES OF 
procuring a second specimen from the same locality, which more nearly approaches the 
var. bedriagw, and which shows that the Z. sardoa cannot be maintained as a species, 
although it probably deserves to rank as a variety distinct from the var. bedriage. 
I have been favoured by Count Peracca with the loan of the type and of the other 
specimen, and I have succeeded in procuring for the British Museum three further 
specimens from Signor Meloni, who obtained them in the same locality. Particulars 
and measurements of them are here given, for comparison with the tables of var. 
bedriage (pp. 412-13) :—

In all the specimens the rostral shield forms a suture with the frontonasai, the 
postnasal is single, the series of granules between the supraoculars and the 
supraciliaries is complete, the parietal is in contact with the upper postocular, 
the masseteric shield is very small or absent, the anterior upper labials are four 
in number, and the whorls of caudal scales are very markedly shorter and longer 
alternately. The parietals may be only once and two-thirds as long as broad. As 
pointed out by Peracca in his excellent description, there are a few extra femoral 
pores, forming an incomplete second series, in the type specimen. 
The coloration of the type specimen has been described with sufficient detail 
by Peracca. His second specimen, smaller but also a female, differs in having 
ihe light dorsal spots larger and fewer and surrounded by a blackish network, 
much as in many specimens of the var. bedriagw; dark markings are very indistinct 
on the olive-brown upper surface of the head, and the belly is uniform greyish, 
unspotted. In two of the specimens received from Signor Meloni, the light 
spots on the body and limbs are surrounded by black rings forming ocelli, between
