Pole rne er forholdsvis korte og indbyrdes omtrent af 
eils Storrelse. lste Par bar Skaftets lste Led storst og 
hengere end de 2 0vrige tilsammen. Svoben er omtrent af 
Skaftets Lsengde og saimnensat af omkring 12 Led. Bi- 
Sv »ben er omtrent lialvt saa, lang og 5-leddet. 2det Par

bliver smalt udtrukket. Den sserdeles store og kraftige 
Lndeklo er stserkt leformigt lcrummet og kan med Spidsen

The lateral plates of the 3rd abdominal segment are 
rather broad, and posteriorly produced to a somewhat up- 
ward-curving, dentiform process. 
Eves in a strict sense, do not occur; but in fresh 
specimens may be observed on either side, within the cover- 
ing of the head, an irregular patch of whitish-opaque pig- 
ment, that apparently corresponds to the ocular pigmentary 
substance. 
The antennae are comparatively short, and about equal 
in size. The 1st pair have the 1st joint of the peduncle 
largest, and longer than the 2 others taken together. The 
flagellum has about the same length as the peduncle, and 
consists of close upon 1 2 articulations. The secondary 
flagellum is nearabout half as long, and five-jointed. The 
2nd pair have the 2 terminal joints well-nigh equal m 
length, and the flagellum — as long as both taken together 
composed of 8 articulations. 
The 2 anterior pairs of legs are exceedingly large, 
and in the female of uniform size and appearance, with 
the hand greatly expanded and compressed from the sides, 
and the palmar margin somewhat obtuse, as also defined 
below merely by an obtuse-angled corner. 
In the male, the 1st pair (see fig. 2 a) is very pe- 
culiarly modified, and also much larger than the 2nd. 
Thus, in particular, the hand occurs prodigiously developed, 
and has a very striking form, the palmar margin being 
deeply emarginate, in such manner that the lowei pait of 
the hand juts forth as an acute, triangular lappet, while 
the upper and foremost part is narrowly drawn out. The 
very large and powerful terminal claw exhibits a prominent 
falciform curve, and admits of being bent in with the point 
towards the aforesaid acute lappet. 
The 2 succeeding pairs of legs are comparatively slender, 
and feeble in structure. On the other hand, the 3 pos- 
terior pairs are rather robust, increasing somewhat in length 
backwards. The basal joint is lamelliform-dilated, and, 
along the posterior margin, crenellated; the last joint is 
conic-acute, and has a very small terminal claw. 
Of the caudal stylets, the 2nd pair is very small, 
scarcely half as long as the 1st. The last pair are both 
longer and more powerful than the 2nd, and have the 
two° branches lanceolate and equal in length. 
The telson reaches considerably beyond the stem of 
the last pair of caudal stylets, and in the middle, is deeply 
cleft, as also armed with several strong spines.

Occurrence and Distribution. — This very distinct 
species was taken on the Expedition in 3 widely distant 
localities. One of these (Stat. 30) lay off Storeggen, the 
2nd (Stat. 224) south of Jan Mayen, the 3rd in the Ba- 
rents’ Sea, between Beeren Eiland and Novaja Zemlja; 
depth ranging from 95 to 417 fathoms. The animal in 
question has however been met with in a fourth locality,
