end of the fourth segment reaches to the middle of the fifth and bears three setae 

 externally. 



In the first peraeopods (text-fig. 2 g) the second segment is a little shorter than 

 the rest of the limb ; its external margin is serrated near the base. The fifth segment 

 is considerably longer than the sixth or seventh. The second peraeopods (text-fig. 2 h)

are a little shorter than the third (text fig. 2Î); the ultimate segment of the former 

 is slender and about as long as the two preceding combined. 



The peduncle of the uropods (text-fig. 1 c) is about one quarter longer than the 

 exopod or endopod, the two latter being subequal. On the inner margin of the 

 peduncle there is a series of from 8 to 11 long spines. The exopod is composed of
