base of the endopod with 4 plumose setae, endopod stout, slightly 

 wider at distal end than at base consisting of only one joint, exopod 

 shorter ending in a long spine. 



Peraeopods : endopod very obscurely segmented, apex recurved, 

 with long plumose setae, scarcely reaching beyond margin of 

 carapace ; endopod broad with median longitudinal rib, outer margin 

 with a few setae ; epipod well developed, apex subacute, outer 

 margin emarginate. 



First pleopod : peduncle with a spine at each apical angle, and a 

 seta on the inner margin near apex, another on outer margin near 

 base; endopod as long as peduncle, apex with one long spine, inner 

 margin glabrous, outer margin setose ; exopod shorter and stouter, 

 inner margin setose, outer margin with short serrate spine-setae, 

 apex with 4, 2 long alternating with 2 short, stout spines ; 

 retinaculum oblong. 



Second and third pleopods : peduncle with one spine on outer 

 apex and a seta near base, inner margin with two groups of 2-4 

 setae, one near base, the other near apex ; endopod with both 

 margins setose ; exopod with 6 pairs of spines on outer margin and 

 3 spines at apex ; scale between exopod and endopod lanceolate ; 

 retinaculum with one margin expanded and serrate. 



Fourth pleopod : similar to second and third but outer apex of 

 peduncle with a quadrate projection and no spine, inner margin with 

 one seta near base. 



Fifth pleopod : basal joint short, second joint twice as long, inner 

 margin setose, the truncate apex with ca. 6 spines and a few setules. 



Sixth pleopod : smaller than fifth, 1-jointed, 4 strong spines on 

 outer distal margin and one small one on inner apex. 



Uropods : in $ equal to last two segments combined, in ? nearly 

 half as long again as last pleon segment, regularly narrowed to 

 subacute apex, inner margin with long plumose setae, outer margin 

 spinose, apex with two long spines, the inner one being rather 

 stouter than the outer. 



Length : 7 mm. from rostrum to end of uropods. 



Colour : Yellowish white, eyes dark red. 



Locality : Cape Town, sewage outlet, July, 1896. 2 ? , one 

 with embryos. (Dr. J. D. F. Gilchrist.) Sea Point, near Cape Town.

This species is well distinguished from both the other species of 

 the genus : N. bipcs (Fabr.) with its several subspecies (Thiele) and 

 N. longicornis, G. M. Thomson, by the character of the dentation on
