segments of the flagellum which decrease in size distally. Second

First thoracic segment shorter than head but longer than 

 segments two to six which are subequal in length; seventh seg- 

 ment one-third shorter than the sixth; fifth and sixth joints the 

 broadest. Coxal plates distinct on all the segments except the first 

 and as long as their respective segments. Legs differing but 

 slightly from each other; first pair the shortest; last four pairs 

 weaker than the preceding; seventh pair the longest. 



Abdomen a little longer than thorax, becoming slightly 

 narrower posteriorly. Telson as broad at insertion of uropods 

 as third segment, and rounded behind. Uropods longer than 

 telson; outer ramus narrow, longer than inner one, with nearly 

 parallel sides and obliquely truncated tip; inner ramus rhom- 

 boidal; peduncle with inner distal angle acute and only slightly 

 produced; uropods and telson setose on posterior margins.
