The legs (figs. 40, 41) are all true pereiopoda, none 
of them modified to serve as organs of prey. They in- 
crease successively in length, the last pair (fig. 41) being 
about half as long again as the first (fig. 40). They are 
rather slender, all perfectly uniform in structure, but spa- 
ringly furnished with bristles, and terminate in a simple, 
faintly curving claw. 
The operculum of the abdomen (see fig. 42) is com- 
paratively very small, occupying but an exceedingly limited 
space on the lower face of the segment, and has an ir- 
regular-rounded form. Its posterior margin is finely ciliated ; 
and, along the middle, runs an obtuse carina, not however, 
as in the typical species, constituting any dentiform projec- 
tion. 
The abdominal limbs — 4 pairs — concealed be- 
neath the operculum, are all true respiratory organs, ex- 
ceedingly soft and fragile, and have no distinct separation 
between the trunk and the terminal plates. 
The 1st pair (fig. 43) have the outer plate very small 
and narrow, densely ciliated along the outer edge and 
furnished at the point with a single strong bristle. 
The 2nd pair (fig. 44) have this plate likewise ex- 
ceedingly small, but of a broader, cordiform shape, and 
furnished along the outer margin with 3 plumous bristles. 
The 2 remaining pairs would appear to consist of 
merely simple, naked plates. 
Thd caudal appendages, jutting forth from the ex- 
tremity of the abdominal segment, immediately within the 
dentiform lateral projections (see figs. 31, 42, and 45), are 
exceedingly small, and, contrary to what is the ease in the 
typical species, quite simple in structure, consisting of but 
one conical joint, furnished with a number of delicate 
bristles. 
Colour of the animal, as in N. oblongus, a uniform 
white, without any trace of pigment. 
Length scarcely, if at all, exceeding 3 mm .

Occurrence and Distribution. — This minute, char- 
acteristic Isopod was taken at 4 different Stations, but in 
each locality isolated, a circumstance that no doubt must 
be partly ascribed to its trifling size and well-nigh incon- 
spicuous colour, which would easily cause it to escape attention. 
Of these Stations, that, with the exception of one (Stat. 290), 
all belong to the cold area, the first (Stat. 33) lies off the 
coast of Romsdalen, the second (Stat. 192) in the open 
sea west of Tromso, the third (Stat. 290) about midway 
between Finmark and Beeren Eiland, and the fourth (Stat. 
51) in the open sea east of Iceland. The depth at these 
Stations ranged from 191 to 1163 fathoms. 
Hence, the tract throughout which the species is at 
present known to be distributed, comprises the great depths 
of the Northern Ocean, extending from the 63rd to the 
73rd parallel of latitude.
