AGAMA FLAVIMACULATA. Ill 
suffused with deep purple ; the throat from the chin backwards to the chest deep 
purple, generally in lines converging to the pouch, which is uniformly purplish brown 
in an adult female. Many of the scales of the body, head and limbs entirely yellow, 
giving a spotted appearance to the lizard ; the spots in some arranged more or less in 
transverse lines across the sides, and on the upper surface of the limbs in transverse 
bars. Under surface yellowish, with occasional purple spots or reticulations ; tail pale 
but bright yellow, obscurely banded with pale brownish, or the bands absent. 
In specimens from Egypt, in alcohol, the general colour is olive-grey or sandy 
yellowish, sometimes with traces of black on the head, back, and sides of the body, but 
more frequently absent ; occasionally many of the scales are pale yellow, but this does 
not occur to the same extent as in Arabian specimens. Underparts yellowish. Tail 
uniform with the body. In the young there is a narrow pale olive-brown band across 
the head between the eyes anteriorly, another behind the eye towards the ear, another 
from the upper angle of the orbit backwards to the shoulder ; two posteriorly divergent 
bands arise on the occiput and pass backwards to the shoulder, but behind this point 
each line is continued interruptedly along the body to the base of the tail in the form 
of 5 short bars, each of which gives off a process passing obliquely upwards and 
forwards to the mesial line of the back, to join a corresponding one from the opposite 
side, while from the posterior end of each bar another process passes obliquely 
backwards and upwards to join its fellow of the opposite side ; by this arrangement five 
pale triangular areas are defined along the mesial line of the back, the centre of each 
being traversed longitudinally by a pale brown spot ; the band from behind the eye is 
continued behind the shoulder along the sides of the body in an almost similar manner. 
In the great majority of the specimens all traces of these bands are lost, but in two 
females (PI. XI. figs. 2 & 3) the longitudinal interrupted continuations of the cervical 
bands remain persistent as light brick-red spots. The figure of A. savignyi, Bum. & 
Bibr. (Descr. de l'Egypte), shows a similar arrangement of spots, and in the type of the 
species the white spots of the mesial line of the back remain, while the bars defining 
them are obsolete. 
None of the specimens from Egypt attain to the dimensions of the lizards from 
Medina, and it may be that they constitute a local race distinguished solely by the 
smaller size of the individuals composing it, and leading into A. tournevillii, Lataste.

With three exceptions all my specimens of this species were obtained in the tract 
of country lying between Suez and Ismailia. One specimen was captured between 
Eosetta and Damietta, and two at Kafr Amar, a village above Cairo, and near to
