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 ram us shorter than inner, with 4 

 single marginal spines. 



Third uropod extending far beyond 1st and 2nd uropods, peduncle 

 with 4 spines on upper apical margin, outer ramus 3 times length of 

 peduncle, 3 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 length of peduncle, with 6-7 apical 

 spines. 



Length: 25 mm., ? 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.) <$ , ovigerous ? ? and 

 young. (S.A.M. Nos. A2258, A2552, A2960, A2968, A3033, etc.) 



Alj. Two large $ specimens, 25 mm. long, caught in the Platteklip 

 Stream (near the " Breakfast Eock "), correspond with the above iivHl 

 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.) 



J'or. a. A form hitherto only found on Muizenberg and KalkBay 

 Mountains and at Buffels Bay, near Cape Point, is distinguished by 

 having the 1st joint of 1st antenna distinctly stouter than the 2nd 

 and the whole 2nd antenna much stouter than 1st. In the <$ this 

 is especially noticeable, and the 2nd antenna is as long as or some- 

 times even a little longer than the first. The telson is somewhat shorter 

 (Plate XXVII. 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.) 



For. ft. 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 ? it is 

 impossible to say whether they are adult. I regard these also, for the 

 present at least, as a variety of capensis.
