EEVISION OF L.M.B.C. AMPHIPODA. 425 



Harpinia neglecta, Sars = il. i^lumosa (Kr.), in Kep. III.

 3/9/87 ; Colwyn Bay, 2^ f. ; Menai Straits, 16/5/91 ; 5 m. 

 W. of Dalby, Isle of Man, 30 f. sandy mud, 8/7/94. 

 Length 3|- mm. 



None of the specimens had the pleon hairy as described 

 by Sars, and as the character of the post antennal angle 

 is very difficult to see I have great hesitation in deter- 

 mining whether they should be referred to this species or 

 to H. plumosa (Kroyer). As, however, the latter appears 

 not to have been met with south of the Arctic circle it is 

 safer to call them H. neglecta.
