Remarks. This form was described and figured by Mr. Farran in the 

 above-quoted Report as the type of his genus Paroithona. It may easily be 

 recognised from the 2 Norwegian species of Oithona described in the present 

 work by its small size and the somewhat less slender form of the body, in 

 which respect it however resembles some exotic species of that genus. From 

 the Indian species, P. palla Farran, it differs among other things in the 

 distinctly 3-articulate outer ramus of the 1st pair of legs, this ramus being in 

 the said species, like the inner, only composed of 2 joints. 



Occurrence. The occurrence of the present form off the Norwegian 

 coast has first been stated by Mr. Farran, who found it not unfrequently in a 

 plankton-sample taken from deep water in the Hundfjord, west coast of Norway 

 (Nordfjord), some of the specimens having kindly been sent to me for ex- 

 amination. I am moreover enabled to state its occurrence in another locality 

 of the Norwegian coast, 2 or 3 female specimens having recently been picked 

 up from a sample of pelagic Copepoda taken by Mr. Nordgaard in the Herl0- 

 fjord, near Bergen. 



Distribution. West coast of Ireland (Farran).

Remarks. I am now disposed to regard the form described by me 

 on p. 14 as C. brevifurca to be more properly identical with the species 

 recorded by Scott from east Finmark under the above name. True there are 

 some apparent differences, chiefly as regards the size *) and the structure of the 

 last pair of legs (according to the figure given); but in all other respects the 

 agreement between these 2 forms are so complete, that I find it unreasonable 

 to keep them apart as distinct species.

Specific Characters. Female. Body not very slender, with the an- 

 terior division oval in outline, greatest width exceeding half the length and 



*) Scott gives the length of his specimen to rather more than 1 mm.
