NEBALIA CAPENSIS, n. sp. 



Carapace oval, smooth, glabrous, without row of setae on hind 

 margin. Rostrum linguiform, 2i- times as long as broad, apex 

 rounded without spiniform projection. Pleon with posterior margins 

 of second to seventh segments dentate, the teeth not triangular but 

 oblong with bluntly rounded apices, placed very closely and 

 regularly, posterior margin on underside of fifth and sixth segments 

 excavate on either side of a median pointed projection, postero- 

 lateral angles of fourth segment acutely pointed; eighth segment 

 with two triangular flaps below the uropods. 



First antenna : first joint shortest, second joint longest, fourth 

 joint with two spines and three setae on outer apical angle, inner 

 angle with a very long and stout seta extending beyond the antennal 

 scale, which is bluntly rounded and strongly setose on outer and 

 apical margins, flagellurn equal in length to peduncle, 7-jointed ; 

 the length is nearly the same in both sexes. 



Second antenna : in $ as long as entire animal, in ? reaching to 

 about base of 1st pleopods, first and second joints subequal, third 

 and fourth coalesced, outer margin proximally with spines and longer 

 setae, both inner and outer apices with plumose setae, flagellum as 

 long as peduncle, 11-jointed, the first joint long and probably com- 

 posed of several joints coalesced. 



Eyes as figured by Sars for N. bipes (I.e. pi. 2, fig. 4), perhaps a 

 little broader, without prominence on upper margin, the pointed 

 squamiform plate at the base a little smaller. 



Mandibles : the small prominence representing the cutting-edge is 

 feebly bifid, without trace of the " comb-like lamella " figured by 

 Thiele for N. bipcs var. valida (I.e. pi. 4, fig. 75). The molar portion 

 has a series of finely fluted transverse lamellae. The palp has the 

 joints gradually increasing in length, setae on third joint in two 

 series, the distal one much shorter than the other. 



First maxilla : outer masticatory lobe larger, setae on its margin 

 mostly bifid, palp long, setose. 



Second maxilla: masticatory lobes three, the middle one smaller 

 than either of the other two, the small rounded projection at the
