112 THE REPTILES OF EGYPT. 
Wasta on the railway to Assiut. I have never seen it alive myself, doubtless owing to 
the fact that I have never been in Egypt during the months when reptilian life is in 
evidence everywhere. 
The native name of this lizard is j ■ | jjj I ^s = kadi el jibdl azrak, or blue 
kadi of the desert. 
I have not met with in Egypt any lizard belonging to the group of which A. agilis 
may be taken as the type. 
In the Supplementary Plates illustrating the account of the Eeptiles in the ' Descr. 
de l'Egypte,' an agamoid lizard is represented on PL i. fig. 5. Audouin held that it 
did not differ from A. agilis, Olivier ; but Dumeril and Bibron, on the other hand, 
considered it to be a distinct species, which they named A. saviqnyi. 
In 1862, Peters received a lizard from Dongola which he referred to A. savignyi ; 
but, in 1869, he altered his opinion regarding it and described it as a new species, 
A. hartmanni. In this last communication he stated that A. savignyi was identical 
with A. flavimaculata, Riippell, and that it was quite distinct from what he styled 
the nearly allied A. agilis, Olivier, to which Dumeril and Bibron have assigned 
A. flavimaculata, Riippell, as a synonym. 
I recently came into possession of five males and three females of A. flavimaculata, 
Riippell : one of them, an adult female, so closely resembles the type which I have 
studied in the Frankfort Museum, also a female, that it may be regarded as typical. 
The remaining specimens are specifically identical with this female. All of them 
were obtained at Medina, Arabia, whereas the type was described from a specimen 
captured at Jiddah. 
I am indebted to Middlemass Bey, Inspector-General of the Coastguard of Egypt, 
for having put me in the way of obtaining the foregoing seventeen lizards which 
I refer to this species, and to Dr. Rogers for a single specimen from the lower 
part of the delta. The specimen from Kafr Amar, a female (PL XI. fig. 3), differs 
considerably from the adult female from Medina in the more equal character of 
its scales and by their little carination, but the seeming gap between the two is filled 
up by other individuals differing still less from the typical form. The variation, 
although considerable, is much less than occurs in A. mutabilis. This Kafr Amar 
female may possibly be the same form as the lizard figured by Savigny and named by 
Dumeril and Bibron A. savignyi, and represented with regular and equal scales. 
They are distinguished from A. agilis, the types of which I have examined on two 
occasions, thanks to the courtesy of Prof. Vaillant and M. Mocquard, by the more 
unequal and irregular character of their scales, in the more strongly keeled ventrals, 
in the presence of a large gular pouch in both sexes, in the absence of true prseanal 
pores, and by their coloration. 
Audouin described the colours of the lizard figured by Savigny evidently from a 
coloured drawing made probably from life, as the colours he describes disappear, as a
