are nearly similar in form and armature to those of the male of 
Dactylopus Strémii (Pl. 3. fig. 8). 
Perhaps the Dactylopus just described ought to be regarded 
as a distinct species, because of the differences which characterize 
both sexes when compared with its nearest of kin, Dactylopus 
Stromi (Baird), but meanwhile I prefer to consider it merely as 
a variety of that species. A number of males and females were 
found.

This species was also washed from the piece of perforated 
wood dredged at Faroe, and is the last I have at present to record. 
Idya furcata appears to have an extensive distribution; it is a 
moderately common form around the British Islands, and it 
sometimes occurs in large numbers in the material washed from 
the filters at the Sea-fish Hatchery of the Fishery Board for 
Scotland ; it has been obtained in gatherings of Copepoda from 
Franz-Josef Land and other places within the Arctic seas, and — 
also in material collected by the aid of a ship’s pump in the 
vicinity of Suez. Its occurrence near Faroe at a depth of over 
80 fathoms is an indication that the species is not limited to 
aittoral or shallow-water conditions.
