Remarks : Agama distanti, Blgr., was described in 1902 by Boulenger to 
include the small Agama which occurs in abundance about Pretoria, the 
chief, and most easily observed, differences from A. hispida being in 
colouration. Boulenger, however, points out that they differ from A. 
hispida also in structural characters, notably in the larger size of the 
ear-opening, and in the absence, or feeble development, of keels on the 
ventral scales of the Transvaal Agama. In calling Agama distanti, 
Blgr., a variety of A. hispida, I am led by the following considerations : 
— The ventral stripe is usually very distinct, but in the large number 
which has passed through my hands, of which only a small part have 
been recorded above, many specimens show the vertebral stripe 
broken up into spots, and sometimes only just indicated. The keels 
on the ventrals are as stated by Boulenger, very often wanting or 
weak ; some specimens, however, agree perfectly in this respect with 
A. hispida. As to the relative size of the ear-opening, I have not 
been able to notice any difference in this respect between the 
specimens of the two species. Boulenger only remarks the larger 
size of the ear-opening in A. distanti than in A. hispida. For the 
latter species he states : Ear-opening small, not quite as large as the 
ear-opening. Summing it all up, while admitting a difference 
to exist, I find that it is chiefly a difference in colouration, and usually, 
but not always in the degree of development of the keels of the 
ventral scales. Under these circumstances I prefer to consider A. 
distanti only as a geographical variety of A. hispida.
