The following species is very near to E. seychellensis Chevreux 

 1901, but differs in having the 3rd joint of the rnandibular palp 

 shorter than the 2nd, the apex of 5th joint of 2nd gnathopod rather 

 more angular and the more expanded 2nd joint of 5th peraeopod. 

 Both species are distinguished from the northern species E. elongata 

 (Bruz.) by the short and slender 2nd joint of the outer ramus of the 

 3rd uropod. 



ERIOPISA CAPENSIS n. sp. 

 (Plate XXVII. Figs. 16-19.) 



Head equal to first two peraeon segments together, rostrum small, 

 autero-lateral angles rounded, eyes absent. Side-plate 1 as deep as 

 the following ones, but much narrower, antei'o-inferior angle produced 

 forwards as a narrow acute process reaching half way along inferior 

 margin of head, 2 and 3 rotundo-quadrate, 4 rotund, deeper than long, 

 not quite as deep as 2 and 3, 5 and 6 feebly bilobed, the anterior lobe 

 deeper than the posterior, 7 longer than deep, deepest in front, 

 posterior angle rounded. 



Pleon segments 1-3 with postero- inferior angles rounded and not 

 serrate. 



Telson cleft almost to base, lobes widely dehiscent, apices subacute, 

 with 3-4 unequal spines, usually a spinule on outer margin just 

 beyond the middle. 



First antenna about half the length of body, 1st joint rather stout, 

 2nd subequal in length but more slender, 3rd scarcely half as long,
