252 MR. G. A. BOULENGER ON SOUTH-AFRICAN [June 6, 
to distinguish it from S. nigricans is not without difficulties. In 
this specimen the cusps in the upper jaw are absent, the posterior 
border of the carapace is very distinctly serrated, the intergular 
shield is twice as long as broad, the length of the outer border of 
the pectoral shield slightly exceeds that of the humeral, and the 
suture between the abdominal shields is shorter than the front 
lobe of the plastron. Head pale brown above, with black 
vermiculations, white beneath, with blackish spots; plastron 
yellowish brown, bordered with black.

7, AGAMA BRACHYURA Bler. 
Klipfontein and Port Nolloth. 
This species was established on a single female specimen 
labelled ‘‘Cape of Good Hope,” from Si A. Smith’s collection. 
I have since examined four specimens collected at Deelfontein by 
Mr. Seimund,and presented to the British Museum by Col. Sloggett, 
and these, together with the six collected by Mr. Grant in British 
Namaqualand, enable me to give a revised description of this 
near ally of Agama hispida. 
Head convex, subcordiform, as long as broad. Nostril not 
tubular, lateral, pierced just below the canthus rostralis in a 
convex nasal. Scales on anterior part of head smooth or rugose, 
sometimes feebly keeled, often trihedral on middle of snout, on 
nack of head more or less strongly keeled, some erect and spinose ; 
occipital enlarged; head about the ears and neck with short 
erect spines. Body strongly depressed, covered with irregular, 
imbricate, strongly keeled scales intermixed with strongly 
enlarged, trihedral, spinose ones; a small nuchal crest, sometimes 
continued along the body ; ventral scales smooth or very feebly
