156 THE REPTILES OF EGYPT. 
the form of the snout of A. savignyi ; but the ventrals vary from 12-14, and externally 
are not well defined oif from the scales of the sides. A small supplementary labial 
excludes the subocular from the labial margin. The dorsal scales are irregular, 
nearly smooth, or obtusely keeled, the temporals are smooth, the digits short, and 
the coloration is that of A. partialis. 
Three other specimens (No. 5849) from the same locality as the former were referred 
by Professor Vaillant to A. savignyi along with a fourth, but much larger individual, 
also from Lasgori (No. *64S4). The latter was the specimen described by M. Lataste 
as A. vaillanti, and by Mr. Boulenger as A. savignyi. One of the three has the first 
and fourth supraoculars completely resolved into small pieces, and the subocular 
entering the labial margin by a fine point. The dorsal scales are rather strongly 
carinated, the digits are short, and the coloration is the same as that of A. partialis. 
The heads of these three specimens are proportionately shorter and heavier than the 
head of A. vaillanti, which resembles that of the specimens from Lasgori that are 
referred to A. vulgaris. The dorsal scales of these three specimens resemble in their 
carination those of A. vaillanti, which has its temporals keeled. 
In all of these specimens, including the type of A. vaillanti, I count 12 ventrals. 
In the largest of the three there are 26 longitudinal rows, 27 and 29 in the other two, 
and 30 in A. vaillanti. The ventrals of the last are proportionally somewhat slightly 
smaller than those of A. partialis. 
In A. vaillanti, the first supraocular is not more decomposed than it occasionally is 
in undoubted examples of A. partialis. In the Paris Museum there is a specimen of 
A. partialis bearing the name A. cruentatus, Pallas (No. ^), in which the first supra- 
ocular, and also the fourth, as stated by M. Lataste, are absolutely decomposed as in 
the figure of A. savignyi. An azygos shield occurs behind the frontonasal as in 
A. vaillanti. The prsefrontals are strongly ridged and the ridges are continued on to 
the frontal, which has consequently a deep median groove. The subocular does not 
border the lip, and lies between the fifth and sixth labials, but the fifth is small on the 
right side and large on the left. The temporals are keeled, but not so strongly as in 
A. vaillanti. The dorsal scales are almost granular anteriorly, large posteriorly, more 
or less imbricate and strongly keeled. The ventrals are broader than long, 10-12 in 
number from side to side, and arranged longitudinally and transversely. The posterior 
prseanal is the largest. The digits are moderately long, the fringe short and strong, 
but not prominent. The hind limb reaches the collar. The colour and markings are 
the same as in A. partialis. The head of this specimen has the form of that generally 
present in A. partialis, but slightly more pointed. This specimen is stated to have 
been obtained in Egypt, and it seems to me to efficiently link the foregoing Somaliland 
lizards, excluding A. vaillanti, to A. partialis, Licht., while at the same time it 
further illustrates the great variability of the species.
