Vi bar taget denne eiendommelige og ioincfaldcnde 
Mphipode paa ilcke niindre end 7 forskjellige Stationer 
p’ l2 4, 164, 192, 240, 286, 359, 362), alle tilhorende 
ko] de Area, Dybden fra 350 til 1004 Favne. Dens 
dbredningsfelt i Nordhavet strsekker sig herefter fra den 
( ^7de til den 80de Bredegrad og fra circa 16° 0. L. til 12° 
• L. Arten forekommer imidlertid ogsaa i Havet 0st af 
pitsbergen, hvor de af Heller beskrevne Exemplarer blev 
D-Sne. Hen er utvivlsomt at betragte som on mgte arktisk 
b orm. 
This peculiar and conspicuous Amphipod was met with 
at not less than 7 different Stations (Stats. 124, 164, 192, 
240, 286, 359, 362) — all in the cold area; depth ranging 
from 350 to 1004 fathoms. Its distribution in the Northern 
Seas extends accordingly from the 67th to the 80th parallel 
of latitude, and from about long. 16° E. to long. 12° W. 
The species occurs, too, off Spitzbergen, the locality from 
which the examples recorded by Heller were derived. 
Hence the animal undoubtedly represents a true Arctic 
form.

Specific Character. — Body somewhat compressed, 
with rather large epimera and with hindmost segments, above, 
sharply defined, but having neither keel nor projection. 
Head "exhibiting a very small rostrum, and with pointed 
lateral corners. Lateral plates of 3rd abdominal segment 
of body well-nigh rectangular. Eyes narrowly oval, with a 
brownish pigment. First pair of antenna) elongate, with 
1st joint of peduncle larger than the 2 succeeding ones 
taken together; 2nd pair scarcely half as long as first. 
First pair of legs feeble in structure; 2nd pair, on the 
other hand, most powerfully developed, with hand greatly 
dilated, and palmar margin somewhat oblique, as also 
armed’ on either side with 4 strong spines. Remaining 
‘airs of legs rather robust, and all about equal in length. 
Last pair of caudal stylets with inner branch more than 
twice as long as outer. Caudal appendages simple rounded. 
Colour whitish-yellow, everywhere specked with red. Length 
$ 7,m . 
Locality. - Stats. 31, 48, 87, 200, 338. 
Remarks. — Of the known species, this form ap- 
proximates closest A. latipes M. Sars, but is distinguished 
bv a less thickset, body, the absence of a dorsal keel, less 
robust ambulatory legs, as also by its colour. More- 
over, the form of the 2 anterior pairs of legs is rather 
different. 
Description. — The body (see PI. XIV, fig. 6) some- 
what thickset, though by no means to the same extent as 
in A utipes, and a good deal compressed from the sides.
