reach 2/3 its length; the claw is small and curved. Pereopods VI are roughly 

 the same length as pereopods V and have roughly the same length ratios of 

 segments, but the distal segments are stronger than in pereopods V, while 

 the 6th segment is 1/3-2/3 the length of the 5th segment or even equal to 

 it. In the short pereopods VII the 4th, 5th, and 6th segments are roughly 

 equal in length, although sometimes the 6th segment is slightly longer or 

 shorter than the 5th; the claw is small and curved. 



The uropods are similar in structure to S. oedicarpus but somewhat 

 broader. Together with specimens which have on the inner margin of 

 uropods I a solitary long spine opposite the place of attachment of the
