en sylforraig Spids. Derimod er Bikløerne forholdsvis meget
mindre end hos hin Art, neppe ’/io saa lang som
Endekloen.
De ydre Ægmasser (se Fig. 3 a) forholder sig omtrent
som hos foregaaende Art. Æggene er yderst smaa og
talrige
Forekomst. Ved vore Kyster synes denne Art kun
at være indskrænket til den arktiske Region; jeg har
saaledes taget den ikke sjelden i Varangerfjord ved Vadsø
paa 60—100 F. D. Under Nordhavs-Expeditionen erholdtes
talrige Exemplarer paa forskjellige Punkter, saaledes ved
Jan Mayen, i Adventbay paa Spitsbergen og i Havet
udenfor Spitsbergens Nordvestkyst (Ståt. 362, 363); Dybden
fra 70 til 459 Favne. Desuden har jeg havt til
Undersøgelse Uere vel udprægede Exemplarer fra det kariske
Hav, indsamlede under Nordenskjølds Expedition 1875;
Dybden 10—80 Favne.
Udbredning. Arten synes at have en vid
Udbredning i de arktiske Have. Deii er saaledes observeret ved
Frants Josephs Land (Heller), i Barents Søen (Hoek), det
kariske Hav (Hansen), Grinnels Land (Miers) og, som jeg
formoder, ogsaa ved Østkysten af Nordamerika (Wilson).
almost as long as the propodal joint, and very narrow,
running out to an awl-shaped point. The auxiliary claws
are, on the contrary, relatively much smaller than in that
species, hardly one-tenth as long as the terminal claw.
The outer egg-masses (see fig. 3 a) have much the
same character as in the preceding species. The ova are
exceedingly small and numerous.
Occurrence. On the coasts of Norway this species
seems to be restricted to the Arctic region. I have, thus,
not infrequently taken the animal in the Varangerfjord
near Vadsø, at a depth of from 60 to 100 fathoms. On
the North-Atlantic Expedition numerous specimens were
collected in divers localities; for instance, off Jan Mayen,
in Advent Bay. Spitzbergen, and in the ocean off the
northwest coast of Spitzbergen (Stats. 362, 363); depth from
70 to 459 fathoms. I have, besides, had sent me for
examination, several well-marked specimens from the Kara
Sea, taken on Nordenskjöld’s Expedition in 1875; depth
from 10 to 80 fathoms.
Distribution. The species seems to be widely
distributed throughout the Arctic Seas. It has been met
with off Frantz Joseph’s Land i Heller), in the Barents Sea
(Hoek). the Kara Sea (Hansen), off Grinnel’s Land (Miers),
and, as I suppose, also on the east coast of North-America
(Wilson).

Artscharacter. Temmelig lig de 2 foregaaende Arter,
men noget spinklere og med Sidefortsatserne videre skilte.
Hovedsegmentet længere end de 3 følgende Segmenter
tilsammen, Halsen tynd, Pandedelen stærkt udvidet.
Øie-knuden særdeles lav, afrundet. Snabelen kortere end
Hoved-segmentet, smalt cylindrisk. Saxlemmerne meget stærkt

Specific Characters. Rather closely resembling the
2 preceding species, but somewhat slenderer, and with the
lateral processes farther apart. Cephalic segment longer
than the 3 following segments taken together, neck thin,
frontal part much expanded. Oculiferous tubercle
exceedingly low, rounded. Proboscis shorter than the cephalic
segment, narrow cylindrical. Chelifori very much elongated
and slender; scape curved at the extremity; hand hardly longer
than the scape, exceedingly arcuate and narrow, fingers same
length as palm, point of the mobile finger incrassated in
tuberculiforin, and of the immobile one unguiformly incurvate,
teeth on inner edge of the fingers, especially on the immobile
one, very unequal in size. Palpi exceedingly thin and elongated.
2nd joint considerably longer than the 3rd, the 2 last joints
equal in length and. taken together, hardly longer than the
3rd. False legs in male about same length as the body, very
thin, 5th joint longest and longer than the terminal part,
marginal spines slender lanceolate and coarsely serrated
