I agree with Mr. Boulenger that A. vaillanti presents a strong resemblance to the 
figure of A. savignyi. The latter, however, gives us no information about the condition 
of the subocular or the character of the temporals, while it only indicates, in a 
general way, the features of the dorsal scales of the lizard it represents. Moreover, it 
only shows the presence of 8 ventral plates at the most. In identifying it with 
A. vaillanti, the existence of a subocular bordering the Up, keeled temporals, and the 
presence of 10 or 12 ventral plates have therefore to be imagined. The evidence of 
the identity of the two is therefore not conclusive. 
A. tristrami is a closely allied species to A. vulgaris and also to A. partialis ; the four 
specimens in the British Museum are adults from Lebanon and Mount Hermon, and 
between Baalbeck and Shtora. The type, a female, was obtained by Canon Tristram 
from the first of these localities, and probably at a considerable elevation. The other 
three specimens were collected by myself at heights varying from 2400 ft. to 3800 ft. 
above the sea-level. The uniformly flattened and non-carinate dorsal scales, their gradual 
passage between the thighs into the granules at the base of the limbs, and their greater 
size on the middle of the back enable it to be distinguished from A. pardalis ; but 
specimens of the latter are now and again met with that show scales here and there 
exactly resembling those of this nearly allied form. The subcaudals at the base 
of the tail, for about a third of its length, are perfectly smooth ; but in many
