Abdomen . — Anteriorly the upper surface carries some short stout 
bristles. 
Posterior spinners with apical segment only a trifle longer than the 
middle segment. 
Posterior sternal sigilla submarginal, about 3 diameters apart. 
Colour. — Dark olive-brown, the carapace nearly black, the abdomen 
dull-purple. 
Measurements. — Total length 8 mm., length of carapace 3 mm. 
This species is very lacking in hairs which often fringe the legs of 
male Pelmatorycters. It is, on the other hand, more bristly than usual : 
the apical margins of the coxae and trochanters of the legs is fringed with 
stiff bristles or in places with actual spines. 
The female, previously referred to by me under the name of lateralis , 
is also characterized by a rather strong development of stiflish setae on 
the sternum and appendages, but these are by no means so well developed 
as in the male. Its most striking character is the wide separation of the 
posterior sternal sigilla which are 2 diameters, more or less, apart, and about 
J a diameter, or less, distant from the sternal margin : the chelicera carries 
7 or 8 teeth. The tuft of setae on the post-ventral border of coxa III is 
not very dense. The abdomen is elongated, sub cylindrical. 
Pelmatorycter sororum, sp. nov. 
Type. — A single adult male example from Bedford, Cape Province, 
collected for the Albany Museum by the Sisters of the Bedford Convent. 
Colour. — Carapace and appendages pale yellowish-brown, the radial 
depressions of the carapace and the median line from the fovea forwards 
being darker than the remainder of the carapace : abdomen dark-purplish 
above with traces of about 5 or 6 pale cross stripes, the lateral and ventral 
regions pale. 
Chelicerae with 7 teeth on the fang groove. 
Pedipalps. — Pressed forwards, the apex reaches as far as the basal 
third of tibia I. Maxillae without denticles at the inferobasal angle. 
Tibia rather short, the spine of the palpal organ reaching backwards 
practically half-way along that segment. 
Legs. — None of the metatarsi are scopulate below, though a few 
scattered scopular hairs may exist at the apex of metatarsus I. Tarsus I 
without spines, II with 2 spines on the posterior side, III with 2 or 3 dorsal 
spines, also 3 on the anterior side and 2 or 3 on the posterior side, IV with 
a row of. 6 spines on the anterior side and 5 on the posterior side. Meta- 
tarsus I with 3 spines at the apex inferiorly and about 4 on the lower 
surface, II with 3 at the apex and 3 or 4 on the lower surface. Tibia I 
sub equal in length to the metatarsus, with 3 spines at the apex inferiorly, 
also about 9-11 on the lower surfaces and 2 or 3 on the anterior surface. 
Coxa III without a distinct compact tuft of stiflish setae post-ventrally. 
Claws of fourth tarsus with about 5 teeth, in each row. 
Posterior spinners. — Terminal segment distinctly shorter than the 
middle segment.
