Agama boulengeri, Lataste, Le Naturaliste, 1886, p. 212. 
Nostril tubular, pierced,in the posterior part of the nasal on the 
canthus rostralis. Upper head-scales keeled; occipital enlarged ; 
sides of head and neck with groups of small spinose scales; ear 
entirely exposed, scarcely larger than the eye-opening ; no regular 
gular pouch. Body feebly compressed ; dorsal scales equal, regular, 
not or very feebly mucronate, feebly imbricate, strongly keeled, the 
keels converging towards the vertebral line; ventrals nearly as 
large as dorsals, smooth; at least one hundred scales round the 
middle of the body; a low nuchal and dorsal crest. Tibia longer © 
than the head; third and fourth fingers equal; fourth toe slightly 
longer than third, fifth extending beyond first. Tail about twice as 
long as the distance from gular fold to vent, very strongly compressed, 
covered with strongly keeled scales forming rather distinct annuli ; 
a very strong crest of long compressed scales bent backwards, much 
more developed than the dorsal. Male with a row of anal pores,

Intermediate between .A. colonorum and A. bibronii. Nostril 
tubular, directed outwards and backwards, pierced below the canthus 
rostralis. Upper head-scales smooth or indistinctly keeled; occi- 
pital enlarged; eight to ten upper labials; sides of head and neck 
with groups of small spines, the largest of which measure hardly 
half the diameter of the tympanum, which is large and entirely 
exposed. A slight nuchal crest. Dorsal scales shortly mucronate, 
‘45 to 50 on the vertebral line between the origin of the fore limbs 
and the origin of the hind limbs, and 74 to 84 round the middle of 
the body. Fourth toe scarcely longer than third, measuring the 
distance between the posterior border of the eye and the end of the 
snout or the anterior border of the nasal shield. Male with a row 
of anal pores. Yellowish or olive above, with usually feebly marked, 
small, dark marblings or reticulations; usually two blackish lines
