A single specimen of this tine species was obtained in a 

 gathering collected between tide- marks at Vadso. This 

 species attains to at least one tenth of an inch in length.

A single female specimen was observed in the Finmark 

 collection ; it occurred in a gathering from Lakse Fiord. 



The fifth pair of feet in this specimen are foliaceous ; the 

 basal joint is subtriangular, with a somewhat broadly but 

 irregularly rounded apex, which reaches to about the end of 

 the secondary joint and is furnished with six moderately 

 short and plumose setje round the lower inner margin and 

 end, but the first seta, counting from the inner margin, is 

 rather shorter and more coarsely plumose, and the space 

 between it and the next seta is greater than that between any 

 of the others ; moreover, the fourth seta, still counting from 

 the inside, is rather more slender than the other five ; the 

 secondary joint is broadly ovate, the breadth being equal to 

 about two thirds of the length; this joint is furnished with 

 six setaj on the lower outer margin and apex ; the basal part 

 of each of the three uppermost sette on the outer margin and 

 the innermost apical seta is comparatively stout, but they 

 become very slender towards tiie end ; the remaining two 

 set£e, which are near the apex and are closer to each other at 

 the base than they are to those on either side, are rather 

 longer and more slender than the other four. Both the inner 

 and the outer margins of the secondary joint ai"e ciliated. 

 Prof. G. S. Brady, in his 'Monograph of the British 

 Copepoda,' states that this is perhaps the most common of
