margins; it may be almost entirely retracted into the body of the 6th 

 segment, which immediately distinguishes H. cryptodactylus from other 

 species of the genus as they do not have retractile claws. The posterior 

 distal angle of the 5th segment of pereopods III has a small triangular 

 process, which is not present in pereopods IV; in the 5th segment of 

 pereopods III and IV the posterior margin is not denticulate, although it 

 bears short marginal setae. The 2nd segment of pereopods VII is stronger 

 than in pereopods V and VI and longer than the 4th and 5th segments 

 together; the 6th segment tapers distally and is almost half the length of 

 the 2nd segment. 



The posterior angle of epimerons I-III is acute. The uropods are 

 strong and have a long peduncle; the rami of uropods III are half the 

 length of the peduncle. The telson is roundish-triangular, with convex 

 lateral margins and rounded apex, and 1/3 the length of the peduncle of 

 uropods III. 



Distribution: Found in a surfacial catch near the Cape of Good Hope. 



Absent in our collections. 



4. Hyperoche martinezi (Miiller, 1864) (Fig. 145) 



Muller, 1864: 54 (Hyperia); Bovallius, 1887a: 20; 1889: 107. 

 Length of males 5-6 mm. 



Male: The head is equal to the first two somites of the pereon in 

 length and wider than long. The two pairs of antennae are approxi- 

 mately equal in length. The 1st segment of the peduncle of antennae I is 

 twice longer than the next two segments together; the 1st segment of the 

 flagellum is cylindrical and approximately the same length as the head;
