 flagellum about 2'/2 as long as broad, consisting of 1 massive Joint tipped 

 with 1 or 2 minute ones almost hidden in the setose clothing. Gnathopod 1 

 chelate, small, 5*^ Joint sh orter than 6**^, which is oblong, a little curved, 

 the Short thumb not strongly produced, stouter than the small finger, which 

 inclines towards it, giving almost a subchelate appearance. Gnathopod 2 

 longer bnt more slender, 5^^ Joint nearlj as long as the narrow, subfusiform 6^\ 

 which ends in a chela smaller but more definite than that of gnathopod 1. 

 Peraeopods 1—5 not elongate; 2^ Joint slightly expanded, 4*'» distally 



widened, b^^ short, 6^^^ distally 

 nan'owed ; finger short, curved; 

 in peraeopods 3 — 5 the 2*^ and

duncle; P^ Joint of inner 

 ramus with inner margin smooth. Uropod 1, peduncle more than twice as 

 long as rami; inner ramus the broader, with 3 apical spinules. Uropod 2 

 attached dose to uropod I; peduncle enormously expanded, the expansion

 with serrate margin; in both sexes rami very short, laminar, apically sen-ate. 

 Uropod 3, attached far from the others; peduncle short, inner ramus oval, 

 minute, not visible from above; outer very large, in d very long, broad, 

 spiuulose, narrowing distally, in g much shorter, but still large, broadly 

 oval, with margin serrate and spinulose. Telson subcarinate dorsally, about
