Type: 1 3 (No.981) found at Durban, Natal, by Mr. J. P. Cregoe,

g . Colowr.—Brown, the distal segments of second leg and the 
2 posterior pairs of legs more yellowish in parts; sternum pale 
yellowish ; coxee of legs pale yellowish, those of pedipalps brownish ; 
abdomen black, the under side pale yellowish, the genital operculum 
brownish behind. ; 
Carapace with a broad band of setiferous granules on each side 
on the cephalic portion, the thoracic portion sparsely granular ; its 
length equalling that of the metatarsus together with + of the tarsus 
of fourth leg, and that of the metatarsus together with 4 the tarsus 
of first leg. 
Ocular area very distinctly longer than wide. The area formed by 
the anterior median and anterior lateral eyes only very slightly wider 
in front than behind and almost twice as long as its posterior width ; 
the median eyes about 4 an eye’s diameter apart; the lateral eyes 
slightly larger than the median eyes, much less than 4 an eye’s 
diameter apart, each situated on the anterior side of a very prominent 
tubercle with the visual axis quite horizontal. The posterior row of 
eyes procurved, the median ones small, a little nearer to the lateral 
eyes than to one another, their outer margins the same distance 
apart as those of the anterior median eyes. 
Pedipalps.—Tibia turgid, about twice as long as the patella or 
tarsus and less than twice as long as high, its upper edge strongly 
convex, its lower edge also convex, the distal part of the infero- 
external surface deeply excavated in the form of a large concave 
notch, the proximal and outer margins of which are furnished with a 
broad semicircular band of short close-set spinules ; tarsus provided 
with a group of spines on the apical dorsal prominence ; the process 
of the bulb broad and strongly flattened at the base but rapidly 
narrowing to the middle, the distal half narrow, flattened, with slight 
spiral twist, dilated again at the apex, which is very obliquely 
truncated. 
Legs.— First leg with the tibia equal to the metatarsus in length, 
slightly wider in the middle than the femur, slightly incrassated 
distally on the inner side and furnished here with 2 stout black 
processes, of which the distal and lower one is very broad and
