projecting and somewhat depressed, minutely spinulose laterally, and terminating 
in a conical point; subrostral corners obsolete. Exposed part of trunk with 
scattered spiniform projections, two of which on each of the 4 anterior segments 
are very conspicuous, forming together dorsally a double longitudinal row, last 
segment with a median spine above, its lateral parts but slightly produced be¬ 
hind, terminating in an acute corner. Caudal segments with the lateral corners 
produced in a similar manner to that in D. Goodsiri, and moreover coarsely 
denticulate. Eye inconspicuous. Superior antennae with the peduncle scarcely 
extending beyond the tip of the pseudorostral projection, its 1st joint longer 
than the other 2 combined. First pair of legs of moderate length, basal joint 
spinulous in its distal part, penultimate joint somewhat longer than both the 
preceding and succeeding joints; 2nd pair with the basal, ischial and meral joints 
spinulous, antepenultimate joint scarcely longer than the last 2 combined; 3rd 
and 4th pairs rather strong, with the basal joint partly denticulate. Uropoda 
with the rami somewhat exceeding half the length of the stem, the inner one 
having the joints well defined, the 1st being somewhat shorter than the other 2 
combined; spinules of the inner edge of usual appearance and about 8 in number 
(4 on the 1st, and 2 on each of the last 2 joints), apical spine rather slender. 
Telson very much produced, extending far beyond the stem of the uropoda, prox¬ 
imal thickened part occupying somewhat more than 1 / 3 of the length, distal part 
armed on each side with about 8 spinules, apical spinules somewhat thicker, but 
scarcely longer than the lateral. Colour pale carneous. Length 18 mm. 
Memories .—This form was first described under the above name by Heller 
from specimens procured at Franz Joseph Land during the Austrio-Hungarian 
Expedition. It is one of the largest known Cumacea, and clearly distinguished 
by the coarse spiny armature of the body. The form described by the present 
author from a single young male specimen procured during the Norwegian North 
Atlantic Expedition as D. nodosa, is very nearly allied to the present species, and 
is even regarded by Dr. Hansen as merely a variety of D. spinulosa. 
Occurrence .—A few specimens of this beautiful form were taken by the 
present author, many years ago, in the Varanger Fjord at Vadso, from a depth 
of about 100 fathoms. During the Norwegian North Atlantic Expedition 2 other 
specimens were found at about the same depth in the Porsanger Fjord. These 
are the only localities of the Norwegian coast where this species has hitherto 
been found. Among the specimens procured are also 2 young males, and both 
af these agreed exactly with the females as regards the armature of the carapace. 
Distribution .—Franz Joseph’ Land (Heller), the Barents Sea (Hoek), the 
Kara Sea (Stuxberg), Greenland (Hansen).
