Skaft, der mod Enden i den indre Kant viser et kort tand- 
formigt Fremspring, og en liden cylindrisk Endesnsert, hvis 
ydre Del er afdelt i korte, med Borster besatte Led. 
lste Fodpar eller de saakaldte Eangarme (se Fig. 1) 
er, ialfald bar Hunnen, af forkoldsvis svag Bygning og 
neppe lsengere end Rygskjoldefc, Pandebornene iberegnede. 
De bestaar ligesom de ovrige Fodder af 7 Led, hvoraf dog 
de to forste er mindre skarpt begrmndsede. Det stserkt j 
forkengede 4de Led (hrachium) er noget fortrykket i Enden 
og oventil her forsynet med et kort knudeformigt Frem- 
spring. Forpvrigt er Fangarmene uden enhver Bevsebning 
og simpelt cylindriske. Haanden er meget smal, neppe 
tykkere end den pvrige Del og omtrent af samme Lsengde 
som de 2 foregaaende Led tilsammen. Fingrene er betyde- 
lig kortere end Palmen, simple, noget boiede og i sin indre 
Kant forsynet med ensformigt udviklede stumpe T tender, 
Naar de lukkes, slutter de feet sammen i sin hele Lsengde. 
De egentlige Gangfodder er temmelig staerkt forlsen- 
gede og ligesom Fangarmene smalt cylindriske, uden tyde- 
lige Tuberkler eller Torner. De aftager snccessivt i Lsengde 
bagtil saaledes, at, medens lste Par omtrent er 1 / 2 Gang 
til saa langt som Fangarmene er sidste Par neppe lsengere 
end disse. Det nsestsidste Led (tarsus) er kjendeligt sma- 
lere end de ovrige og temmelig forlsenget. Endekloen er 
kraftigt udviklet og paa a, lie Par af ens Udseende, svagt 
boiet, nsesten trind, ikke sammentrykt, og i Storsteparten 
af sin Laengde tset besat med de eiendommelige ovenfor 
omtalte kapselformige Hudvedbseng, bvormed ogsaa den 
Ovrige Del af Fodderne er rigeligt forsynet. Den aller- 
yderste Del af Endekloen er derimod ganske nogen og af 
en meget fast honiagtig Cousistens samt sylformigt tilspidset 
(se Fig. 4). 
Farven er overalt ensformig skidden graabrun, hvad 
der forOvrigt vajsentlig skyldes de tsette Hudvedbseng, der 
overalt dsekker Legemet. 
Udmaalinger. Det storste af de to undersogte Ex- 
emplarer har en Spandvidde mellem de ndstrakte forreste 
Gangfodder af 250” m . Rygskjoldets Lsengde er, naar Pan- 
dehornene fraregnes, 45”™, dets storste Brede 42”™ ; Pande- 
bornenes Lsengde 25”™; lste Par Gangfodders Lsengde 
120'""’; Fangarmenes Lsengde udstrakt 70” m . 
Forekomst og Udbredning. Kservserende mserkelige 
Krabbe blev forst opdaget under den Porcupine’ske Expedi- 
tion paa den saakaldte Holteniagrund i den vestlige Del 
af FserO-Sbetlandsrenden og er afbildet i det bekjendte af 
posing tbis part diminish successively in thickness and 
are each thickly clothed with hair. The exognath issues 
from the outer side of the 2nd segment of the stem, and 
consists of a somewhat bevelled, slightly arcuate ped- 
uncle, which, towards the extremity, at the inner margin, 
exhibits a short, dentiform projection, and at the apex a 
small cylindric flagellum, the outer part of which is sub- 
divided into small articulations, beset with bristles. 
The 1st pair of legs, or chelipeds as they are called 
(see fig. 1), exhibit, in the females at least, a compara- 
tively feeble structure, and are scarcely at all longer than 
the carapax, including the rostrum. Like the other legs, 
they are composed of 7 segments, of which however the 
two first are less sharply defined. The very elongate 4th 
segment (hrachium) is somewhat dilated at the extremity, 
and here, above, furnished with a short, tuberculiform pro- 
jection. For the rest, the chelipeds are simple cylindric, 
without any armature whatsoever. The hand is exceed- 
ingly narrow, scarcely at all thicker than the remaining 
part, and about of the same length as the 2 preceding 
segments taken together. The fingers are considerably 
shorter than the palm, simple, somewhat bent, and on 
their inner margin provided with obtuse, uniformly developed 
teeth. When shut, they fit close together, throughout their 
entire length. 
' The true ambulatory legs are comparatively elongate, 
and, like the chelipeds, slender and cylindric, without distinct 
tubercles or spines. They diminish successively in . length 
posteriorly, in such manner that, whereas the 1st pair are 
about half as long again as the chelipeds, the last pair are 
scarcely at all longer than those limbs. The penultimate seg- 
ment (tarsus) is appreciably narrower than the preceding ones, 
and rather elongate. The terminal claw is most power- 
fully developed, and on each pair of uniform appearance, 
slightly curved, almost round, not compressed, and through- 
out the greater part of its length thickly beset with the 
characteristic capsular cutaneous appendages described above, 
with which, too, the remaining portion of the pereiopoda is 
abundantly furnished. The outermost part of the terminal 
claw is, on the other hand, entirely naked, of an exceed- 
ingly firm, corneous consistence, and acutely pointed (see 
fig. 4). 
Colour everywhere a uniform dirty greyish -brown, 
chiefly ascribable to the compact cutaneous appendages that 
cover the whole surface of the body. 
Measurements. — The largest of the two specimens 
examined has a width between the expanded anterior perei- 
opoda of 25”™. The length of the carapax, exclusive of 
the rostrum, is 45”™, its greatest breadth 42”™ ; the length 
of the rostral horns is 25"™; the 1st pair of pereiopoda has 
a length of 120”™; the length of the chelipeds, expanded, 
is 70”™. 
Occurrence and Distribution. — This remarkable 
crab was first observed on the “Porcupine” Expedition, 
inhabiting the “Holtenia ground,” in the western part 
of the Fseroe-Shetland channel: the animal is figured in
