Anledning til Artsbenævnelsen; naar den slaaes ind mod
Haanden, moder den med Spidsen den bagre Portsats.
Farven er gulagtig, halv gjennemsigtig, og navnlig hos
Hunnen marmoreret med brunrødt Pigment.
Længden af den ægbærende Hun er omtrent 6mm.
Hannen er noget større, nemlig 7’"™.
Forekomst. 2 Exemplarer af denne Art, en Hun
og en Han, toges under Expeditionens sidste Togt i den
isfyldte Magdalenebay paa Nordvestsiden af Spitsbergen;
Dybden 10—20 Favne. Samme Art forekommer ogsaa af
og til ved vore Kyster, navnlig ved Finmarken. Efter
Boeck skal den gaa sydlig lige til Christianiafjorden.

(Pi. XVIII, Fig-, i, i a).
Dulichia hirticornis, (t. O. Sars, Prodromus descriptions etc., No. 134.
Artscharacteristic. Legemet forholdsvis robust, noget
nedtrykt, glat. Hovedet fortil stumpt koniskt. Øinene smaa,
ovalrunde, hvidgule. Folerne kraftigt udviklede, i den bagre
Kant tæt besatte med lange Børsteknipper; lste Par af
mere end Legemets Længde, med Skaftets lste Led saa
langt som Hovedet, 3die Led længere end 2det, Bisvøben
liden, 3-leddet. 2det Fodpar hos Hunnen af samme
Udseende som lste, hos Hannen betydelig større, tæt haaret,
med særdeles stor og bred, sammentrykt Haand, der nedentil
gaar ud i 2 skraat fortilrettede dolkformige Fortsatser, den
bagerste størst og omtrent beliggende ved Midten af
Haandens Længde. 3die og 4de Fodpar med noget udvidet
Hofteled. De 3 bagerste Fodpar ualmindelig robuste og
næsten indbyrdes af ens Længde. Legemet gjennemsigtigt,
med hvidgult Pigment. Længden 11"’™.
Findesteder. Ståt. 18, 31, 200.
Bemærkninger. Denne Art er let kjendelig fra de
tidligere beskrevne ved sin ualmindelig plumpe Kropsform,
de forholdsvis robuste og tæt haarede Følere og de smaa
hvidgule Øine.
Beskrivelse af Hunnen. Legemet ei’ (se PI. XVIII,
Fig. 1) i Sammenligning med de øvrige bekjendte Arter af
Slægten usædvanlig plumpt, stærkt nedtrykt, med bred
hvælvet Ryg og uden Pigge eller Fortsatser.
terminal claw is very powerful, and exhibits at the base
2 small protuberances, a character that gave rise to the
specific designation; when jerked in toward the hand, its
point conies in contact with the posterior prolation.
Colour yellowish, semi-translucent, and, more especially
in the female, marbled over with a brownish-red pigment.
Length of the ovigerous female about 6""". The male
is a trifle larger, viz. 7mm.
Occurrence. — Two individuals of this species, a male
and a female, were taken on the Expedition (last cruise)
in the ice-encumbered Magdalena Bay, north-west shore of
Spitzbergen; depth ranging from 10 to 20 fathoms. The
same species occurs too, now and again, off the coasts of
Norway, in particular the coast of Finmark. According to
Boeck, its habitat is known to range as far south as the
Christianiafjord.
70. Dulichia hirticornis. G. O. Sars, n. sp.
(Pl. XVIII, fig. 1, 1 a).
Dulichia hirticornis, G. O. Sars, Prodromus descriptionis etc., No. 1114.
Specific Character. — Body comparatively robust,
somewhat depressed, smooth. Head anteriorly conico-obtuse.
Eyes small, in form a rounded oval, colour whity-yellow.
Antenna* powerfully developed; along posterior margin densely
beset with long fascicles of bristles; 1st pair greater in
length than body, with 1st joint of peduncle as long as
head, 3rd joint longer than 2nd, secondary flagellum small,
tri-articulate. Second pair of legs, in female, of same
appearance as 1st, in male considerably larger, densely hirsute,
with hand exceedingly large broad and compressed, jutting
below as 2 oblique, forward-directed, mueronifonu
prola-tions, posterior prolation the larger, and placed about in
middle of hand longitudinally. Third and 4th pair of legs
with slightly dilated basal joint. The 3 posterior pairs of
legs remarkably robust, and well-nigh equal in length. Body
translucent, with whity-yellow pigment. Length 1 lmm.
Locality. — Stats. IS, 31, 200.
Remarks. — This species is easily distinguishable from
those previously described by its remarkably clumsy form
of body, comparatively robust and densely hirsute antennæ,
and small whitish-yellow eyes.
Description of the Female. — The body (see PI.
XVIII, fig. 1), as compared with the other known species
of the genus, is unusually clumsy in form, very much
depressed, the back broadly arched, and without either
spikes or spiniform prolations.
