no trace of inferior fringe. Enlarged lateral gular scales only traceable 
below the rictus oris. Occipital horns moderate, each with a short ac- 
cessory horn at the external base ; internal temporal horn half as long 
as the occipital, with a short accessory horn at the external base; ex- 
ternal temporal horn very short, and the temporal anterior to it pre- 
senting a serrate edge only. Infralabials presenting a serrate edge only ; 
parietal region bounded on each side by an angulated border which 
overhangs the temporal region. 
Squamation of the head smaller than in other species; superior 
labials twelve, below the middle of the eye, instead of eight or nine in 
A. platyrhina the nearest allied species. Seven subequal scales in the 
transverse row between the canthal rows on the frontal angle; there 
are five unequal scales on the corresponding position in the A. platy- 
rhina. Six longitudinal rows of supraocular scales, of which a group 
of five or six posterior to the middle are larger, but unequal. Supra- 
orbital: rows in contact, except at points, on the median line; last 
superciliary presenting a sharp angle; penultimate also presenting a 
prominent angle. Tomia of mouth only moderately serrate; a row of 
conic scales rising posteriorly on the side of the neck, and above its 
posterior end an inconspicuous rosette. A conspicuous rosette above 
the middle of the humerus. 
This species is nearest to the A. platyrhina Gir. from which it differs 
in various respects. The general proportions of all the parts and the 
coloration are about as in that species, the difference chiefly appearing 
in the squamation and the horns. The scales of the head are much 
more ‘subdivided, and the presence of accessory horns is unique in the 
genus. The simplicity of the lateral fringe is also characteristic, as is 
also the rudimental character of the rosette on the neck.

I may add here that in my estimation the genus Anota Hallow. is 
valid. It includes the species A. modesta Gir., A. goodei Stjen., A. 
platyrhina Gir., A. maccallii Hallow., and the above described. 
ScELOPORUS VANDENBURGIANUS Cope.—This is a small species with 
small scales and very dark colors. There is not much difference in
