of posterior spinners a trifle shorter than the middle segment : anterior 
median eyes slightly raised on a tubercle, about If to nearly 2 diameters 
apart and about If diameter distant from the anterior laterals : posterior 
medians small, posterior laterals a trifle longer than the distance between 
the anterior and posterior laterals : abdomen elongate ovoid, rather than, 
subcylindrical as in P. brevipalpis. 
Specimens from the same locality, which I suppose to be merely half- 
grown examples of the same species, have the following characters : — 
Chelicerae with 8 teeth : maxilla with 1 or 2 cusps at the anterior 
basal corner below, and, in addition, some small weak spinules scattered 
about on the ventral surface : the scopula on metatarsus II posteriorly 
is not continued to the base : claws of tarsus IV with distinct teeth, some- 
times 4 : posterior sternal sigilla elongated and pear-shaped. 
Measurements of large specimen taken between Lyttelton Junction 
and Irene. — Total length 32 mm., length of carapace 11 *25, breadth of 
carapace 9 mm. 
Other examples of this species were taken by Messrs. A. Boberts and 
G. van Dam at Mayville, Pretoria North, Wonderboom Poort, Skinners 
Court, between Yillieria and Derdepoort, Eoodeplaat, Zeekoegat, near 
Eoodeplaat, and from Schoemans Bust, near Crocodile Eiver Bridge ; 
the specimen from the last locality is young and has rather widely separated 
sigilla. 
Pelmatorycter pretonae , Hewitt, var. nov. rufescens. 
Type. — An adult male from Eoodeplaat, Pretoria District, collected 
by Mr. G. van Dam (22nd May, 1915). A second example was subse- 
quently taken in the same locality. 
This form is somewhat smaller than the type of pretonae (Becords 
Albany Museum, II, p. 427), which came from Garstfontein, but principally 
differs therefrom in the complete absence of a scopula at the apex of 
metatarsus II inferiorly. Other characters are : — Metatarsus I with only 
a very short scopula at the apex inferiorly : II with 2 spines (instead of 1) 
along the ventral surface : tibia II with 2 or 3 spines (instead of 4) on the 
lower surface : no spines on any of the tarsi, except in the second example,, 
which has a single spine on the anterior side of tarsus IY : no denticles 
at the anterobasal angle of the maxillae : tibia of palp hardly so long 
as in pretonae , relatively to the length of the palpal organ (this character 
not quite identical in the two examples) : pressed forwards the palp 
extends to a point about § of the distance along tibia I : apical segment 
of posterior spinners decidedly shorter than the penultimate segment 
(apparently subequal in pretoriae). 
Colour. — Carapace and appendages pale reddish-brown, darker on the 
cephalic area. 
Measurements. — Total length 14 mm., length of carapace 4 -7. 
Female . 
A female example preserved in the same tube with the type presents 
the following characters : — 9 teeth on the fang groove : maxillae with 
4 or 5 small cusps at the anterobasal angle (only 1 or 2 in another example
