Forekomst og Udbredning. 2 Exemplarer af denne 
it toges under Expeditionens lste Togt udenior Storeggen 
■ tat ; 31) f ra et Dyb af 417 Favne . Under 2det Togt 
bjentandtes samme Art paa en vidt adskilt Lokalitet, nemlig 
>il dan Mayen (Stat. 237), hvor ligeledes 2 Exemplarer 
and the head, has a rough appearance, from numerous minute 
spikes, comparatively equal in development alike on the 
upper surface and along the lateral margins. On the 2 
posterior segments, spikes are entirely wanting, and the 
integuments would, too, appear to be thinner and more 
cutaneous. The penultimate segment has, above, in the 
middle, a distinctly marked longitudinal sulcus, from which 
a shorter one extends transversely on either side, producing, 
as it were, a cruciform depression in the middle. The last 
segment is posteriorly deeply emarginate, and has the lateral 
corners obtusely rounded. 
The posterior division of the body is uniformly arched 
above, and smooth, without a trace ot spikes. The epimera, 
however, are, as in the preceding species, pointed, and pro- 
ject toward the sides, being also furnished at the point 
with short bristles. 
The eyes, contrary to what is the case in the preced- 
ing species, are distinctly developed, though rather small, 
and have then* position at the sides of the head, immediately 
posterior to the supraorbital projections. Their pigment 
is of a dark, blackish colour. 
The antenna: do not differ essentially in structure 
from those of the preceding species. 
The mandibles, on the other hand, are relatively 
somewhat larger, and have the extremity produced, as also 
acutely pointed. On the outer margin, occurs, about in 
the middle, a distinct, though small, dentiform projection. 
The 2 remaining pairs of oral appendages do not 
differ essentially from those in A. stygius. 
The legs, too, present a very close resemblance in 
form, though less abundantly furnished with bristles; more- 
over, the tuberculiform teeth are not so fully developed. 
On the pleopoda, is wanting likewise every trace of 
bristles, and the branches have a similar appearance to 
those in the preceding species. 
The median caudal plate (fig. 24) is relatively shorter 
and broader, and comparatively of a regular triangular form, 
with the extremity produced to a sharp point, from which 
proceed 2 rather long, diverging bristles; 2 similar bristles 
are attached to the upper surface, a little posterior to the 
middle. 
The outer caudal appendages exhibit nothing distinct- 
ive in their structure. The terminal plates have no teeth 
on the edges, whereas the marginal bristles are relatively 
more developed than in the preceding species. 
Colour a dirty grey, with a faint brownish tinge, the 
2 posterior segments of the anterior division having, from 
the viscera that shine through the integuments, a somewhat 
darker shade than the rest of the body. 
Length only about 5 1 / a”""; hence, scarcely half that 
of the preceding species. 
Occurrence and Distribution. — Of this species, 2 
specimens were taken on the 1st cruise of the Expedition, 
off the Storeggen Bank (Stat. 31), at a depth of 417 fath- 
oms. On the 2nd cruise, the same species was again 
met with, in a widely different locality, viz. — south-west
