the latter segment being less than two and a half times as long as wide. There are 

 stout setae on the ventral margins of all the segments except the ischium and, on the 

 upper margin, on the carpus and at the distal ends of the ischium and merus. 



In the fifth pair (text-fig. 35/;) the exopod is short and broad, not reaching 

 much beyond the middle of the ischium. The merus and carpus are subequal in 

 length, about one and a half times the length of the propodus. The latter segment 

 is a little shorter than the dactylus. On the ventral margins of the ischium and

merus there is, among others of more slender build, a single stout seta; otherwise 

 the limb is clad in setae much as in the fourth pair. 



The first four abdominal somites are smoothly rounded dorsally ; the pleura of 

 the first two are greatly enlarged in the female. The fifth .somite is very obscurely 

 carinate in the mid-dorsal fine, but the carina is not produced posteriorly as a spine. 

 The sixth somite is smoothly rounded above ; at its anterior end there is a short 

 transverse ridge on the dorsal surface which, in lateral view, has the apearance of a 

 tubercle. On the posterior margin there is a pair of small spinules, one on either 

 side, overhanging the articulation of the telson. The ventral margins are fringed with
