Second antenna, 3rd and 5th joints subequal, 4th a little shorter, 

 flagellum equal to last peduncular joint, obscurely 3-jointed, 

 flagellum and all peduncular joints except 1st apically setose. 



Upper lip tapering to the blunt apex, sides concave, distal one- 

 quarter abruptly narrowed.

 apices, outer margins rather densely setose. 



Mandibles elongate, triangular, with acute piercing apex, palp 

 stout, 2nd joint thrice as long as 1st, 3rd shorter than 1st, with 

 2 apical pectinate setae. 



First maxilla long, very narrow, apex serrulate on inner margin. 



Maxilliped, 1st joint indistinguishable, 2nd 3J times as long as 3rd 

 joint which is obliquely bevelled off on the outer margin to the acute, 

 setiferous apex, 4th joint barely distinguishable, inner apex of 2nd 

 joint with 4 long setae. 



First peraeopod, 2nd and 3rd joints subequal, 2f times as long as 

 wide, both margins of 3rd setose, 4th short but wide, basal margin 

 semicircular, 5th joint with 6 serrate spines and long setae on inner 

 margin, 6th joint oval, produced at base of palm into a strong 

 tubercle bearing a serrulate spine on its apex, palm slightly convex, 

 with serrulate spines and short apically recurved setae, 7th joint 

 stout, abutting on tubercle at base of palm, inner margin with 

 regularly spaced groups of short stout setae, unguis short ; tubercle 

 at base of palm not nearly so prominent in $ . 



Second and third peraeopods similar to first, but not quite so

 margin of 5th joint with only 2 spines, no tubercle at base of palm 

 of 6th joint, outer margin of 6th strongly setose, 7th joint pro-

 ramus covering inner ramus and the other pleopods, ovate, inner 

 ramus nearly as long as outer and half as wide, both rami apically 

 setose. 



Second pleopod, rami subequal, apices rounded, with indications
