Lepidosis. — Upper parts with strongly keeled scales, some of which may be 
mucronate, with few or moderately numerous, irregularly scattered enlarged 
ones, the mucronate or spinous character of which is more pronounced ; lateral 
scales pointing towards the vertebral line ; groups of spinose scales on the 
side of the neck and behind the ear-opening, the largest much shorter than 
the diameter of the latter ; a low nuchal crest, continued along the back as a 
series of slightly enlarged, more strongly keeled scales ; 90 to 100 scales round 
the body. Upper head- scales smooth or obtusely keeled, 10 to 14? across from 
one superciliary series to the other; occipital scale moderately or feebly 
enlarged (larger in the young) ; 11 to 14 upper labials on each side ; 3 to 5 
series of scales between the upper labials and the nasal. Gular and ventral 
scales more or less distinctly keeled, not or but feebly mucronate, except on 
the sides. Scales on upper surface of limbs equal; scale at the base of the 
clawj'on the dorsal surface of the toes, tricarinate and much longer than the 
others ; subdigital scales extremely spinose, the tips of the spines often dark 
brown or black, 13 to 16 in a longitudinal series under the third toe. 
Caudal scales strongly keeled, not forming whorls, subequal in size; the 
vertebral series forming a low serrated edge or crest. 
Male with a single series of rather large preanal pores. 
Coloration. — Pale yellowish or greyish brown above, uniform, or with 4 
or 5 pairs of dark spots or wavy cross-bands on the body, separated by a 
vertebral series of pale oval or rhombic spots or by a yellow vertebral band. ; 
limbs and tail with more or less distinct dark cross-bands. Lower parts 
white, throat usually with wavy dark longitudinal lines ; male with a central 
dark patch on the throat. 
Habitat. — Angola and Namaqualand. The British Museum collection 
contains, in addition to two specimens (from Caconda and Catumbella) 
received from the late Prof. Barboza du Bocage, several obtained in Benguella 
(Caconda, Catumbella, Maconja, Huxe, Cuangu) by Dr. Ansorge. We have 
also examined specimens from Namaqualand (Groas, Matahole) in the 
South African Museum.
