 4 largest, much deeper than 5. Postero-inferior angle of 3rd pleon 

 segment quadrate, scarcely produced. 



Telson entire, subrectangular, distal margin straight, 2-3 minute 

 setules at the rounded postero-lateral angles. 



First antenna, 1st joint stout, 2nd and 3rd subequal, flagellum in

Second antenna subequal to 1st, ultimate joint a trifle longer than 

 penultimate. Flagellum in < 7-, in ? 6-jointed. 



Upper lip, distal margin evenly rounded. 



Mandibles, cutting-edge 4-5-dentate, secondary cutting-edge 3-4-

Maxilliped, the 2 outermost teeth on apex of inner plate large, 

 4th joint of palp small, conical, ending in a long seta. 



First and second gnathopods similar to one another and alike in 

 both sexes, 2nd and 3rd joints not in the least expanded, 5th distally 

 f ringed with 6-8 setae, 6th nearly twice as long as broad, inferior 

 margin slightly concave, palm transverse, convex, setulose, defining

Fifth paraeopod, 2nd joint very strongly expanded, as broad as long, 

 hind margin serrulate, 6th as in 3rd and 4th peraeopods.
