CRUSTACEA COPEPODA. II. 3 
These plates do not reach beyond the end of the anal segment; each plate has the posterior margin transverse 
and a little convex, with three strong setee, while the fourth seta is placed on the outer margin much nearer 
to its base than to the terminal margin; in reality the caudal rami agree — also in one of the type-spe- 
cimens, as to shape and length with Wilson’s fig. 234 and not with fig. 21 of the Danish authors. On the exopod 
of fourth legs I found 3 spines, as drawn by Steenstrup & Liitken, while Wilson has only 2; the equipment 
of the antennulee agrees with the figure and description of the Danish authors, not with Wilson’s statement, 
and the same is the case as to the posterior lobes of the carapace. The differences between Wilson’s specimen 
from the boreal Pacific and the Atlantic specimens are, however, so small that they may be due to individual 
or geographical variation. 
Occurrence. — Not taken by the “Ingolf”’, but in pelagic hauls at a good number of places.

Distribution. — This species has been taken several times somewhat south of the “Ingolf’”’ area 
at the following places: Lat. 58°40’ N., Long. 30°40’ W., surface, “Tjalfe’; 1 specimen. — Lat. 58°24’ N., 
Long. 30°35’ W., 500 m. wire out, “Tjalfe’”’; 1 specimen. — Lat. 59°41’ N., Long. 25°02’ W., 500 m. wire out, 
“Tyjalfe” ; 3 specimens. — Lat. 59°25’ N., Long. 22°56’ W., surface, “Tjalfe’; 1 specimen. — Lat. 58° N.., 
Long. 19° W., Inspektor Olrik (Stp. & Ltk.). — Lat. 59° N., Long. 8° W. Captain Moberg (Stp. & Ltk.). 
Besides the “Thor’”’ has gathered NV. borealis at two places South-West of Ireland, viz. at Lat. 51°28’ N., 
Long. 11°50’ W., I specimen; and Lat. 51°00’ N., Long. 11°43’ W., I specimen. T. & A. Scott does not men- 
tion it from Great Britain; Wilson records a specimen from Alaska.
