segments is almost 4.5 times the width; the 6th segment is narrow and 

 shghtly longer than the 5th. Pereopods VII are about half the length of 

 pair VI; the 2nd segment is broadened (pyriform), its maximum width 

 (in proximal 1/3) four times the width along the distal margin, its length 

 255 about twice the maximum width; the 4th-6th segments are narrow, equal 

 in length, have a denticulate anterior margin, with dense setae in the 

 distal part of the 5th and a few rows of setae on the 6th segment; the 

 claw is short and not more than 1/5 the length of the 6th segment. 



The urosome is short and together with the uropods not longer than 

 the pleon. The uropods are broad, with denticulate basipodites whose 

 length is 2.5 times the width. The basipodite of uropods I attains maxi- 

 mum width in the middle, of uropods Ill-distally; the rami are approxi- 

 mately equal in length, in uropods I not more than half the length of the 

 basipodite and in uropods III, 2/3. 



The description given is after Stephensen (1918). 



Distribution: Four catches of this species (males) are known — all
