sig ved betydeligere Storrelse. F odleddet er meget kraf- 
tigt udviklet, ikke fuldt 4 Gauge laengere end bredt og 
temiiielig stserkt krummet. Dot er langs den ydre Kant 
og ved Euden besat med en Del uregelmsessigt fordelte 
Tomer, hvoraf den til det ydre tilspidsede Hjprne fa-stede 
er storst. Inderkauten af Leddet er jevnt indbugtet og 
danner ved Basis en bred pladetormig L'dvidning ; langs 
hvilken til sseregne Afsatser or fsestet o meget stsarke for- 
til krummede Torner, hvoraf dog de 2 yderste er stillede 
jevnsides ; foran dem folger en Bad af omkring 7 noget 
mindro Torner. Endekloen er meget kraftig, mere end 
halvt saa lang som Fodleddet. mod hvis indre tornbesatte 
Kant den kan iiulboies. Den er stasrkt krummet og v eel 
Basis fortil forsvnet med 2 vel udviklede, til en sseregen 
Afsats fiestedo Biklper, der omtrent er afEndekloens halve 
Luengde. De 2 ovenbeskrevne sidste Led tilligomed Ende- 
kloen danner et meget kraftigt Griberedskab, hvormed 
Dyret kan klamre sig fast til Hydroider og andre Gjen- 
stande paa Havbunden. 
Integumenterne er temmelig tykke, af kederagtig Oon- 
sistens og overalt forsynede med srnaa circulate Felt (Aab- 
ninger for Hudkjertler). De er hos det levende Dyr tem- 
melig gjennemsigtige, saa at forskjellige af de indre Orga- 
ner mere eller miudre tvdeligt skinner igjennem. navnlig 
den intensiv gronfarvede Tarm med sine lige ind i Fod- 
leddet rsekkende Sideforlsengelser. Seet fra Bugsiden viser 
sig ogsaa Buggangliekjaeden med sine 5 store Gangliei 
meget tydeligt (se Fig. 3 a) skinnende igjennem Huden.

Forekomst. Jeg har lain taget denne Form paa en 
eneste Localitet ved vor Vestkyst, Remuesp ved Stavanger, 
paa nogle faa Favnes Dyb mellem Alger og Hydroider. 
I vort Museum opbevares imidlertid en Del Exemplarer 
tagne af min Fader ved Fiord og Manger, og et enkelt 
Individ fra Sdndmdr. Kroyers Exemplarer var ligeledes 
fra vor Vestkyst. 
Udbredning. Arten er aabenbart en mere sydlig 
Form: thi Jarzynsky’s Angivelse af dens Forekomst ved 
Russisk Lapland tror jeg mo a bero paa en Feiltagelse. 
projects outwards as a narrow lobe, beset with 2 small 
bristles; its inner margin is considerably arched and armed 
with several spines, one of these exhibiting a much larger 
size. The propodus is very powerfully developed, not 
quite 4 times as long as broad, and rather sharply cimed. 
Along the outer margin, and at the extremity, it is beset 
with a number of irregularly disposed spines, of which 
that affixed to the sharp outer corner is largest. The 
inner margin of the joint is uniformly incuryate, and 
constitutes at the base a broad lamellar expansion, along 
which are affixed, to separate ledges, 5 very strong, 
anteriorly bending spines, the 2 outermost however being 
in juxtaposition ; in front of them extends a series of 
about 7 somewhat smaller spines. The terminal claw is 
very powerful, more than half the length of the propodus, 
against the inner spiniferous margin of which it admits 
of being bent. It is strongly curved, and furnished at the 
base anteriorly with 2 well-developed auxiliary claws, affixed 
to a special ledge, and attaining about half the length of 
the terminal claw. The 2 last joints, described above, 
together with the terminal claw, constitute an exceedingly 
powerful prehensile organ, by means of which the animal 
can clasp hold of Hydroids and other objects met with 
on the sea-bed. 
The integuments are rather thick, coriaceous in con- 
sistence, and everywhere provided with small circular 
areas (openings for the euticular glands). In the living ani- 
mal, they are comparatively translucent, so that divers of 
the inner organs shine more or less distinctly through, in 
particular the dark green-coloured intestine, with its lateral 
prolongations extending even into the propodus. Viewed 
from the ventral side, the nervous chord, with its 5 large 
ganglia, can also be seen, shining through the skin (see 
fig. 3 a). 
None of the specimens I examined were ovigerous. 
But according to Dohrn, the males are furnished at times 
with a large number of globular egg-masses adhering to 
the false legs, which often quite cover the under surface 
of the body and contain each of them numerous minute 
ova. 
The colour of the animal, more especially owing to 
the translucent intestine with its caecal prolongations, has 
a more or less pronounced green, seldom a brownish tint. 
Occurrence. — 1 I have taken this form in but a 
single locality, on the west coast of Norway, Renneso near 
Stavanger, at the depth of a few fathoms, between Algae 
and Hydroidae. In the University Museum, however, are 
preserved divers specimens collected by my father at Flore 
and Manger, as also a solitary individual from Sondmpr. 
Krpyer’s specimens were likewise from the west coast of 
the country. 
Distribution. — The species is evidently more of 
a southern form; for Jarzynky’s statement as to its occur- 
rence on the coast of Russian Lapland, must, I certainly
