pallidipes : in this respect peringueyi resembles austerus. The male of 
peringueyi has a coarsely granulated humerus and a nearly smooth hand, 
somewhat as in jpaUidijpes : in austerus the upper surface of the hand is 
nearly as strongly granular as the humerus, and the inner margin of the 
hand is more strongly denticulated than in peringueyi or pallidipes, resem- 
bling harrooensis in the latter respect : the under surface of the hand is 
almost devoid of granules in pjeriiigueyi and pallidipes.

Distribution ; Type believed to come from Walfisch Bay. Kraepelin has 
described a male example from the same locality (11) and recorded the 
species also from Hereroland (12). 
20. 0. KARROoENSis Purcell (PI. XXV, figs. 65 and 58), Ann. S. Af. Mus. 
vol. i, p. 1, pis. i and ii, and 153, also ii, p. 196, 1898. 
The types were taken at Prince Albert Village ; Dr. Purcell records it 
also from Laingsburg (Buffels River), Prince Albert Division, Beaufort 
West, Victoria West, Ashton and Hotbaths Eobertson Division. The 
Albany Museum has it from Jansenville, from Dirkskraal, Somerset East 
District (B. Marais), Huevel Kraal, near Steytlerville (Miss A. G-eard), 
from near Williston (C. Hassard), and from near Uniondale Road (J. L. 
Drege). 
The shape of the hand in males which appear to be sexually mature 
varies considerably even in specimens from the same locality. Two examples 
from Victoria West, of the same length of carapace, have the length and 
breadth of the hand as follows : 26 x 6*1 and 23-5 x 6-8. It is possible 
that even sexually mature examples may accjuire longer and narrower hands 
at each moult. 
The posterior crest marking off the upper and posterior surfaces of the 
brachium is well defined in this species and its nearest allies ; it occurs also in 
austerus, fossor, and pallidipes ; it is weak in latimanus, carinatus, hreviceps, 
chaperi, and peringueyi, and obsolete in granifrons, pictus, glahrifrons, macer, 
crassimanus, capensis, wahlbergi, and granicauda. It is obsolete in Hetero- 
metrus and in Pandiiius viator is. 
21. O. LONGicAUDA Purcell (PI. XXV, fig. 54), Ann. S. Af. Mus. vol. i, 
p. 168 and ii, p. 195, 1898. 
Distribution : The types were taken at Naroep in G-reat Bushnianland. 
Other localities cited by Dr. Purcell are Wortel near Naroep, Hunitsamas 
near Eamond's Drift on the Orange River, Beenbreek on the Orange River, 
Zwartniodder and Beestert in the north of Kenhardt Division. We have it 
from Kakamas (Miss Olivier). 
The great breadth of the vesicle is a feature of this species.
