in d, ultimate Joint of peduucle longer thän penultimate, flagellum with 50 joints, 

 most with calceoli as in flagellum of antenna 1. Maxilla 1, 10 spine-teeth on 

 apex of palp. Maxillipeds, 5 small spines on apical border of outer plates. 

 Gnathopod 1, 6*^ Joint longer tban 5*^, palm verj oblique and very ill-defined.

 palm. üropod 2, inner ramus strongly constricted. Uropod 3, rami narrowly 

 lanceolate, carrying spinules and setae, inner scarcely longer than basal Joint 

 of outer. Telson not quite twice as long as broad, cleft nearly to base, with
