of the inferior ones, flagellum composed of only 4 joints, including the very small
apical one. Inferior antenna) rather slender, with the flagellum longer
than the
peduncle. Legs comparatively slender, though less rapidly increasing in length
posteriorly than in the 2 preceding species; 1st pair, as usual, much the shortest,
with the carpus somewhat shorter than the propodos, and armed inside with 3
spines; last pair scarcely longer than the body, carpal joint somewhat dilated
distally. Uropoda obliquely truncated at the tip,
and setous at each corner.
Colour dark brown, from numerous pigmentary spots forming irregular shadows.
Length of adult female scarcely reaching
to 3 mm.
Remarks. This species was established by Kroyer from Greenland spe-
cimens; but its true specitic characters were not fully recognized. For the figures
given by the same author in the great work of Gaiinard, evidently belong
to two
distinct species, confounded by him at that time. From the 2 preceding species,
it may be distinguished by the comparatively more slender inferior antenna?, the
less elongated legs, and the form and armature of the caudal segment. It is also
rather inferior in size, and always exhibits a very dark colour.
Occurrence. The species is rather common off the Lofoten Islands and
along the whole Finmark coast, in moderate depths, among Hydroida. It also
occurs occasionally off the west coast of Norway, but nowhere in any abundance.
Distribution. Greenland (Kroyer), Atlantic coast of North America (Harger),
Iceland and Spitsbergen (Norw. North Atl. Exped.).

Specific Characters. Body of female somewhat robust,
with the anterior
division oval in form, and the segments very sharply marked off from each other,
and clothed laterally with scattered hairs. Body in male, as usual, much narrower.
Ocular processes conically tapered. Caudal segment comparatively short, scarcely
more than half as long as the uiesosome, and rounded oval in form, lateral edges
rather bulging in front, and each armed with 4 strong denticles, the posterior
pair subdorsal, tip bluntly produced, and without any serrated lamellae. Eyes
comparatively small, at least in female. Superior antennae very short, extending
not nearly to the middle of the penultimate peduncular joint of the inferior ones,
flagellum composed of only 3 articulations, including the very small apical joint.
