palp has no finger, but these points are doubtful without description. 

 Gnathopod 1, 3*^ Joint prominent, 3^ — 6*^^ strongly setose on hind margin, 

 b^^ scarcely so long or broad as 6*^; palm of 6**^ short, transverse, overlapped 

 by the small pectinate finger. Gnathopod 2, 2*^ and 6**^ joints with veiy 

 long plumose setae fringing front margin; 5*^ Joint a little longer, not 

 broader, than 6*^, widening distally; 6^^ narrowing to small oblique palm, 

 defined by a strong palmar spine; finger rather strong, curved, smooth» 

 Peraeopods 1 and 2 rather long. Peraeopod 3 short, peraeopod 4 a little, 

 and peraeopod 5 much longer; 2'^ Joint of peraeopods 3 — 5 narrowly oblong 

 oval, üropods 1 and 2 rather stout; rami a little unequal. Uropod 3 very 

 Short; rami equal, elliptic or ovate, scarcely as long as the short, stout 

 peduncle. Telson veiy short, twice as broad as long; sides con verging to
