D. salisburii, sp. nov. 
The types are several adult male examples and one adult female 
collected at Grahamstown on the forested slopes above the Albany 
Hospital during February, 1915. The species is named after Mr. F. S. 
Salisbury, M.A., who has made important contributions to our knowledge 
of the flora of this portion of South Africa and has rendered great service 
to the Albany Museum on various occasions. 
Colour . — Carapace and legs blackish, the former thinly margined 
with pale-yellow and with a thin yellow median stripe bifurcating behind 
at the fovea : pale-yellowish or white hairs are also found on the upper 
surfaces of the coxae, trochanters, and basal parts of the femora. The 
abdomen is bright-orange dorsally, the coloured area being sharply 
defined and broken only by a short median black streak anteriorly. 
Ventral surfaces blackish. The ventral and lateral surfaces of the abdomen 
are faintly tinged with yellow, owing to the presence of fine plumose hairs 
which occur along with the more conspicuous black simple hairs which are 
.longer and stiffer. 
Ocular area . — Anteromedians about half the size of the anterolaterals, 
a trifle more than a diameter apart, but only about \ a diameter distant 
from the anterolaterals. Posterior row broader than the anterior row, 
the medians only a mere trifle nearer to each other than to the laterals. 
Distance from anterior lateral to anterior margin of the carapace rather 
greater than the diameter of an eye. 
Chelicerae . — In the female the basal joint is shorter and stouter than 
in the male, and the dentition accordingly is different, the distal tooth 
of each row being much more widely separated from its neighbour in the 
male than in the female. The strongest tooth is the middle one of the 
inner row. 
Legs.— All the tarsi and the two anterior metatarsi are scopulate to 
the base. In the female there is a scopula in the distal half of tibia I on 
its anterior side, but such is not the case in the male. Tarsus IV is not 
so decidedly scopulate as I and II, the hairs being more setiform. Near 
the base of metatarsus I interiorly is a pair of spines in the male, but not 
in the female. Metatarsus II with a pair of spines near the base interiorly 
in both sexes. Tibia I with two pairs of spines interiorly, II with only 
two unpaired spines below. Metatarsi III and IV and tibiae III and IV 
with a pair of spines at the apex interiorly, and, in addition, two pairs of 
rather long and strong spines on the lower surface : besides, there are 
several similar spines on the lateral surfaces of each segment so that near 
to the apex of the metatarsi there are in all about 6 spines. Femora I and II 
have about 2 or 3 spines superiorly whilst III and IV have about 5 superior 
spines. None of the tarsi are spined. Fine plumose hairs occur on the 
legs as well as stiff black ones. 
Male palp . — The tibia is produced distally into a stout straight 
process acuminately pointed at the end. What seems to be the spine of 
the bulbal organ arises from an expanded lamina, which is mostly not 
pigmented and suddenly contracts into a fairly slender dark-coloured 
process, which is strongly hooked near its apex. Besides this, the palpal
