"TERRA NOVA" EXPEDITION. 



Remarks. — I have examined two of Mr. Hodgson's syntypes. One is immature, 

 and the other, an adult female, is of a slender type with very long legs and with the 

 femora less dilated than is usual in this sex. In other respects it resembles very 

 closely indeed the slender male here figured (Fig. 14) except that the lateral processes 

 are not so well separated. 



Achelia intermedia, sp. n. (Text-fig. 15). 



Occurrence. — Station 220, off Cape Adare, 45-50 fathoms ; 5 $, 6 <? (inch 

 Holotype). 



Description. — The specimens that are referred to this species difter from the 

 more compact forms of A. spicata only in the following points : — 



(1) The lateral processes are all in contact and the segmentation of the body is

obliterated, the limits of the somites being marked only by faint grooves. The trunk 

 is relatively shorter, less than one-third longer than the proboscis. 



(2) The chelophores are much shorter, not extending beyond one-third of the 

 length of the proboscis. 



(3) The abdomen is shorter, not reaching to the middle of the coxse of the last 

 pair. 



In all these characters the specimens approach those described below as A. hrucei. 

 From these, however, they are at once distinguished by the short auxiliary claws and 

 by the much higher ocular tubercle.
