it is found in the southern coastal areas of Africa, Australia and South

3. Hyperia macrocephala (Dana, 1853) (Fig. 132) 



Dana, 1853: 988 (Tauria); Bate, 1862: 296; Bovallius, 1889: 81 (Tau- 

 ria); Spandl, 1927: 156; Shoemaker, 1945b: 291; Bowman, 1973: 13. 



Length of adult specimens up to 29 mm. 



The height of the head is more than half the length of the pereon and 

 its length equal to somites I and II together. Antennae I and II in females 

 are approximately equal in length and half the height of the head. The 

 outer lobes of the maxillipeds are armed with only short setae and the 

 inner lobes are shorter than the outer. 



Coxal plates IV in adult specimens are acute and project sideward. 

 Pereopods I and II are approximately equal in length; the 2nd segment 

 is broadened; the 3rd and 4th segments are short and the posterior distal 

 angle of the 4th produced into a small lobe, which is better developed 

 in pereopods II; the 5th segment is broadened, with a straightly truncate 

 distal margin, and obconical; the 6th segment is approximately equal to 

 the 5th in length but much narrower; the claw is straight. Pereopods III 

 and IV are much longer than pairs I and II; the 2nd segment is broadened;
