De to Par egentlige Gangfødder er (se Fig. 8) af
middelmaadig Længde, omtrent saa lange som hoire
Fangarm, sammentrykte fra Siderne og langs den forreste Kant
af de to ydre Led grovt tandede og haarede. Endekloen
er temmelig smækker, adskilligt længere end det
foregaaende Led og uden Spor af Torner, men besat med lange
spredte Haar.
De to bageste Fodpar viser den for Familien
cha-racteristiske rudimentære Bygning og er især mod Enden
besatte med lnnge og tætte Borsteknipper.
Bagkroppens Vedhæng viser intet udmærkende i sin
Bygning.
Farven er hvidagtig med et svagt gulrødt Skjær.

Forekomst og Udbredning. Arten er først opdaget
af Norman ved Shetlandsøerne og i al Korthed
characteri-seret i den af ham givne Rapport over en Del af det her
indsamlede Materiale.
Det af os tagne Exemplar erholdtes i Havet udenfor
vor Vestkyst, noget indenfor den bekjendte Fiskegrund,
Storeggen (Ståt. 25) fra et Dyb af 98Favne. Exemplaret
beboede en gammel Skal af Sipho islandicus.
Ifolge den af Norman givne Papport over den Franske
Expedition i Biskayerbugten. er den ogsaa forefundet lier
paa større Dyb.
Artens hidtil bekjendte geographiske Udbredning er
saaledes omtrent den samme som for den i det foregaaende
beskrevne Krabbe, Scyramathia Carpenteri. og ligesom denne
maa den betragtes som en mere sydlig Fonn.
a dentate carina, projecting considerably backward. The
fingers are appreciably longer than the palm, and the
moveable finger is connected with the hand by an
extremely-oblique articulation.
The two pairs of true ambulatory legs (see fig. 8) are of
moderate leugtb, about as long as the right cheliped.
compressed. and, along the anterior margin of the two outer
segments, coarsely dentate and ciliated; the terminal claw
is comparatively slender, a good deal longer than the
preceding segment, and without any trace of spines, but
exhibiting scattered hairs.
The two posterior pairs of legs have the
rudimentary structure characteristic of the family, and are, more
particularly at the extremity, beset with long and thick
bunches of bristles.
The appendages of the posterior division of the body
exhibit nothing peculiar in their structure.
Colour whitish, with a faint yellowish-red tint.
31easurements. — The specimen examined measures
from the frontal margin to the posterior curvature of the
abdomen 30"""; the right cheliped, fully exserted. has a
length of 30»’"’.
Occurrence and Distribution. — The species was
discovered by Norman, off the Shetland Isles, and briefly
characterized by that author in his Report of part of the
zoological material collected there.
The example obtained on the Norwegian Expedition
was brought up at sea. off the west coast of Norway, a short
distance within the well-known fishing-bank "Storeggen"
(Ståt. 25), from a depth of 98 fathoms. The specimen
inhabited an old shell of Sipho islandicus.
According to the Report given by Norman of the
French Expedition in the Bay of Biscay, the said form
was met with there in greater depths.
The geographical distribution of the species, as known
up to the present time, is accordingly about the same as
that of the crab described above, Scyramathia Carpenteri,
and. in common with that animal, the species must be
regarded as a more southern form.
