from same locality) : no stiff setae on the post-ventral border of coxa III: 
posterior sternal sigilla about § of a long diameter apart, and about the 
same amount distant from the sternal margin. The distal segments of the 
palps and first two pairs of legs from the patella onwards are noticeably 
paler than the more basal segments. 
Total length 20 mm. 
At present I am unable to distinguish between the females of this 
variety and of the typical form. 
Pelmatorycter brevipalpis, sp. nov. (Text fig. 6, No. 4.) 
Type. — An adult male example from Roodeplaat (17 miles north-east 
of Pretoria), collected by Messrs. Gr. van Dam and A. Roberts (5th April, 
1915). 
Colour. — Carapace and appendages dull olive-brown throughout : 
abdomen dull-purplish above. 
Chelicerae with 6 or 7 teeth in the inner row. 
Pedipalps. — Pressed forwards, the apex of the palp reaches a point 
only a trifle beyond the apex of the patella of the first leg. Tibia com- 
paratively short, the tip of the spine of the bulbal organ reaching back 
to a point about half-way along the length of the tibia. Maxilla with 
2 denticles at the anterobasal corner. 
Legs. — Tarsi completely without spines. Metatarsi quite without 
scopulae. Tibia I very slightly longer than metatarsus I. Metatarsus I 
with 1 spine at the apex interiorly and 2 along the lower surface : II with 
2 or 3 at the apex and 2 on the lower surface. Tibia I with 2 or 3 spines 
at the apex interiorly and 2 on the lower surface, but none on the sides. 
Coxa III with a patch of bristles along the posteroventral border : this 
patch is not so dense as in the female. Patella IV without spines. Claws 
of tarsus IV (absent from one leg) with an inner row of 7-9 teeth and an 
outer row of about 3 or 4 teeth. 
Posterior spinners with apical segment slightly shorter than the middle 
segment. 
Posterior sternal sigilla about J of a diameter distant from the sternal 
margin and nearly 2 diameters distant from each other. 
Ocular area apparently not very distinctive. Distance between 
anterior and posterior lateral eyes scarcely equal to -J of the length of the 
posterior laterals (in pretoriae equal to quite § or more of the length of 
the posterior laterals). 
Abdomen with long bristles, but no spines at the base above. 
Measurements. — Total length 11 -75 mm., length of carapace 3 *75 mm. 
The weak development of spines on the tibia of the first leg is a marked 
feature of this species. 
Female. 
In the same tube as the type male there is a small female which no 
doubt belongs to the same species, but may not be quite mature. Its chief 
icharacters are as follows : — 
Chelicerae with 6 teeth on the fang groove. 
Maxilla with 1 or 2 denticles at the anterobasal angle inferiorly.
