segment is barely broadened, its anterior margin straight or slightly con- 

 cave and unevenly denticulate, and the maximum width of the segment 

 occurs in its proximal part; the successive segments are narrow and long, 

 420 the 5th the shortest of them; the 4th and 6th segments are about equal 

 in length; the 4th and 5th bear sparse short setae on the anterior margin, 

 while the anterior part of the 6th segment is covered with tiny setules. 

 The 2nd segment of pereopods VI is more strongly broadened than in 

 pereopods V, its anterior margin straight or weakly bulged and indis- 

 tinctly denticulate, and the posterior margin strongly bulged proximally; 

 the 3rd segment has a somewhat downwardly projecting anterior margin; 

 of the remaining segments, the 4th is the longest and the anterior mar- 

 gin has complex denticulation (the denticles are grouped and their size 

 increases distally within each group); the 5th-6th segments have a uni- 

 formly denticulate anterior margin. The 2nd segment of pereopods VII 

 is broadest proximally, its length twice its width and equal to the total 

 length of the remaining segments, each of which is narrower and shorter 

 than the preceding one.
