Posterior spinners. Terminal segment subequal to or very slightly longer 
than the middle segment. 
Colour. Carapace and chelicerae brown, sometimes with a dull red tinge 
on the head region, but usually very darkly pigmented : legs brown : abdomen 
infuscated above and below, or somewhat paler below than above. 
Measurements. Total length 11-7, length of carapace 4, breadth of cara- 
pace 3. 
It may eventually seem advisable to separate generically this, and- other 
species, characterised by the presence of horned femora in the adult male; in 
such case a new name will have to be framed, as there is no evidence that a 
horned femur occurs in either of Simon’s species of Ancylotrypa. However, 
no basis for division can be discovered in the characters of the females. 
Stasimopus nigellus Poc. 
The Transvaal Museum has a series of four adult male and numerous 
female examples of this species from Venterskroon, taken March 31, 1917, by 
Messrs A. Roberts and G. van Dam. 
The females agree closely with that described by me from Kroonstad under 
the name of S. dreyeri and are perhaps specifically identical therewith. The 
band of spinules on the upper surface of metatarsus I extends over scarcely 
more than one-fifth to about one-third of the dorsal length of the segment and 
is generally quite twice as long as that at the apex of the tibia. Tibia of palp 
with spinules apically above, but metatarsus III without spines or spiniform 
setae at apex below. The distance between anterior lateral and anterior median 
eyes is rather less than the long diameter of the former. Length of carapace 
10 mm.: breadth of carapace 8-8. 
The males are, I think, specifically identical with 5 . nigellus Poc. There is, 
however, no trace of a scopula at the apex of metatarsus I. Pressed forwards, 
the palp reaches about one-quarter of the distance along metatarsus I. Patella 
of palp only a little longer than patella I. Tarsus III may be quite devoid of 
spines on the anterior surface, or may have four or five weak ones. Patella III 
with 2-5 short spines on the anterior surface. Anterior median eyes about a 
diameter apart, or slightly more. 
This is easily distinguished from S. minor mihi, a Bloemfontein species, by 
the measurements of the palp in comparison with those of the first leg. 
Length of carapace 4-7, breadth of carapace 4-2, length of patella of palp 
2 -5, length of patella I 2, of tibia 13-7. 
The type example of 5 . minor has the following measurements : patella of 
palp 2-8, patella I 1-9, tibia 13-1. 
Stasimopus tysoni sp. nov. 
This species is founded on a series of specimens collected at Port Alfred, 
including one adult male presented by Mr W. Tyson and some adult female 
examples from various donors (Misses E. and L. Britten, Mr F. Salisbury). 
The male is comparatively large, agreeing in size with that of schonlandi 
Poc. from Grahamstown, and of spinipes mihi from East London: the female 
is rather small, being considerably smaller than adults of schonlandi. The 
characters of the male are not very distinctive : it agrees closely with the males 
of spinipes and of schonlandi in the elongation of the segments of the palps and
