low transverse roller. The lower posterior angles are rounded in all the 

 somites while the anterior angles in somites I and VI-VII are slightly 

 stretched forward but not acute. The coxal plates of somites I and II are 

 small and low, both with a horizontal keel. Somites III-V are high while 

 somites VI-VII are low. 



Pereopods I and II have a chela formed by the 5th and 6th seg- 

 ments. The distal posterior angle of the 5th segment of pereopods I is 

 stretched into a broad and acute lobe, extending in females to 3/4 the 

 length of the 6th segment and in males, to its distal end; the 6th segment 

 is oval, with a straightly truncate distal margin, and its distal posterior 

 angle stretches into a small lobe. The lobe of the 5th segment of pere- 

 opods II is narrower than in pereopods I and extends to the distal end 

 of the 6th segment; the 2nd segment is narrower than in pereopods I. 

 the 2nd segment of pereopods III and IV is distally broadened, clavate; 

 the 6th segment is thin, slightly curved; the claw is very small. Pere- 

 opods V-VI are somewhat longer than pereopods IV; the 2nd segment 

 abruptly broadens distally; the 6th segment is narrowly conical, slightly 

 curved; the claw is very small and weak. Pereopods VII are similar to
