Amphipoda IJyperiidea collected by the * Discovery.' 253 



The nearest allies of this species would seem to be V. jean- 

 gerardi and V. longipes. 



Jt resembles the former in the possession of a rostrate head 

 and in the fusion of the second and third ural segments, 

 while the length of the fifth and sixth walking-legs in rela- 

 tion to the preceding ones recalls V. longipes. 



From both these forms V. hodgsoni is quite distinct, in 

 that (1) the hinder corners of the last ural segment are 

 distinctly produced backward, and (2) the seventh walking- 

 leg is of aberrant and quite characteristic shape. 



It is curious to notice that in two points (viz. the curious 

 structure of the seventh leg and the serrated epimeral plates) 

 this species presents some resemblance to V. serrata ; but it 

 is easily distinguished by (1) the form of the first antenna, 

 (2) the feebler serrations on the margins of the epimeral 

 plates, and (3) the form of the seventh leg, which has the 

 hinder portion of the inferior margin considerably produced 

 downwards. 



It is to be regretted that in the present collection there is 

 no female of this species or of V. serrata.
