Crustacean Fauna of South Africa. 205 
5 marginal spines and bundles of setae, outer with 5 pairs of marginal 
spines, both with 3-5 unequal apical spines. 
Second uropod shorter, outer ramus shorter than inner, with 4 
single marginal spines. 
Third uropod extending far beyond Ist and 2nd uropods, peduncle 
with 4 spines on upper apical margin, outer ramus 3 times length of 
peduncle, 8 pairs of spines along outer margin, 5 pairs along inner, 
both margins densely setose, 3-4 apical spines, 2nd joint small, with 
a terminal spine, inner ramus 3 length of peduncle, with 6-7 apical 
spines. 
Length: § 25mm., 2 15-18 mm. 
Colour : Pale pinkish, eyes pale red, somewhat glistening; in spirit, 
whitish, eyes chalky-white, or more frequently becoming almost 
invisible. 
Locality: In the streams on Table Mountain, Muizenberg Moun- 
tain, and probably throughout the Cape Peninsula, but not apparently 
descending below 300 feet. (K.H.B.) gd, ovigerous 2? 2 and 
young. (S.A.M. Nos. A2258, A2552, A2960, A2968, A3033, etc.) 
Ab.—T wo large 3 specimens, 25 mm. long, caught in the Platteklip 
Stream (near the ‘‘ Breakfast Rock’’), correspond with the above in all 
points except the antero-inferior angle of side-plate 4, which is quad- 
rate with a short sharp point similar to that of the postero-lateral 
angle. I have never found any more specimens resembling these 
two and regard them merely as an aberration of capensis. (S.A.M. 
No. A195.) 
Var. «.—A form hitherto only found on Muizenberg and Kalk Bay 
Mountains and at Buffels Bay, near Cape Point, is distinguished by 
having the Ist joint of 1st antenna distinctly stouter than the 2nd 
and the whole 2nd antenna much stouter than Ist. In the ¢ this 
is especially noticeable, and the 2nd antenna is as long as or some- 
times even alittle longer than the first. The telson is somewhat shorter 
(Plate XX VII. Fig. 22). The pleon is in some specimens less, but 
as a rule very much more densely setose than in the typical capensis. 
(S.A.M. Nos. A2272, A2961, A3084, and A3374.) 
Var. 6.—A very similar form lives on the Cape Flats (Newlands 
and Wynberg. Dr. W. F. Purcell, S.A.M. Nos. 10017, 10021), but 
differs in having the 6th joint of gnathopods 1 and 2 distinctly wider 
distally than proximally. The specimens are smaller than the average 
of capensis, but as there are only 2 and neither is an ovigerous 9 it is 
impossible to say whether they are adult. I regard these also, for the 
present at least, as a variety of capensis.
