. 0-5mm 025mm Fig. io. Nyctiphanes capensis. a, fifth furcilia, cephalothorax in dorsal view; b, second antenna; c, telson; d, sixth furcilia, peduncle of first antenna; e, second antenna;/, juvenile telson. The first four cormopods have their full complement of segments; the first is feebly kneed, the second to the fourth powerfully so. The fifth cormopod is unaltered and the remainder are rudimentary. The telson still carries three pairs of postero-lateral spines and three terminal spines. Fifth furcilia. Thirteen specimens examined (Fig. loa-c). Length range 4-5-4-9 mm.; average length 4-7
