Fig. 256. Hemiscelus diplochelatus Stewart, female (after Stewart, 1913). 



The 2nd segment of pereopods I is linear and equal in length to the 

 distal 3rd-7th segments; the 4th segment is slightly broadened distally 

 and equal in width and length; the posterior distal process of the 5th 

 segment does not reach the middle of the 6th segment and the margins 

 of the process are smooth; the claw is 1/3 the length of the 6th segment. 

 The 2nd segment of pereopods II is longer than in pereopods I and also 

 longer than the distal segments together; the 4th segment is longer than 

 its width; the posterior distal process of the 5th segment is 2/3 the length 

 of the 6th segment; the claw is half the length of the 6th segment. The 

 2nd segment of pereo- pods V is oval and its width 1/2 its length; the 

 7th segment appears to be a smooth continuation of the 6th segment and 

 is almost the same length; the distal segments together are shorter than 

 the 2nd segment. The 2nd segment of pereopods VI is slipper-shaped 

 and has no lateral fissure; the distal segments are lost. The 2nd segment 

 of pereopods VII is moderately broadened and shorter than the distal
