Head not produced in front. Antennae strong and setose; antenna 

 one much longer than antenna two, flagellum longer than peduncle, 

 accessory flagellum present; antenna two with peduncle about twice 

 as long as flagellum. Mouth parts normal. Gnathopod one sub- 

 chelate, fifth joint longer but not broader than sixth. Gnathopod 

 two in female and left guathopod two in male similar to gnathopod 

 one, though with the sixth joint longest and strongest. Right gnath- 

 opod two in male with sixth joint very large and powerful. Perae- 

 opods one and two long and slender. Peraeopods three to five stronger 

 and very long; much alike, fifth slightly longest; second joint ex- 

 panded, sixth joint longer than any other except second. Uropods 

 one and two with rather strong, unequal rami. Uropod three a con- 

 cave, spinose plate projecting over lateral margin of telson. Telson 

 rectangular. 



This genus is evidently nearest the genus Duliclna, but differs 

 from it particularly in the character of the first antenna, second 

 right gnathopod of male, shape of peraeopods three to five, presence 

 of rudimentary third uropods and shape of telson.
