her ethvert Spor af de fine Tsender i Inderkanten, som An- 
des hos unge Individer af hin Art, og har Spidserne noget 
stserkere indboiede. 
De falske Fodder er forholdsvis kjendelig Isengere end 
hos foregaaende Art, hos Hunnen (so Fig. 4 a) omtrent af 
Legemets Lsengde, hos Hannon (Fig. 4) betydelig Isengere 
og som hos foregaaende Art .forsynede med en konisk Flig 
ved Enden af 5te Led. De 4 ydre Led er langs Inder- 
kanten bevaebnede med en regelimessig Rad af saugtakkede 
Torner (se Fig. 4 e). Endekloen er forholdsvis Isengere end 
hos P. circularis og har flere Tsender i Inderkanten. 
Gangfodderne (se Fig. 4) udmserker sig ved sin be- 
tydelige Lsengde, der nsesten er 4 Gange saa stor som Le- 
gemets. De er overalt tart besatte med pigformige, borste- 
bserende Fortsatser, der dog er betydelig mindre end hos 
foregaaende Art og ganske glatte i Kauterne. Af Hofteled- 
dene er det 2det stserkt forlsenget, betydelig lasngere end de 
2 ovrige tilsammen. Laarleddet er bos Hunnen temmelig 
stserkt opsvulmet paaMidten, hos Hanuen (Fig. 4) betydelig 
smalere og noget buet. lste Lsegled er omtrent af Laar- 
leddcts Lsengde, medens 2det er kjendelig Isengere og meget 
smalt. Tarsalleddet (se Fig. 4 f) er noget stor re end hos 
foregaaende Art, skraat afskaaret i Enden og i Inderkanten 
bevsebnet med flere, udad i Lsengde tiltagende Torner. 
Fodleddet er najsten ret, forholdsvis smalere end hos P. cir- 
cularis og bevsebnet i Inderkanten med stserke Torner, bvoraf 
navnlig de 4 oiler 5 bagerste udmserker sig ved betydelig 
Storrelse, Endekloen er kraftigt udviklet, leformigt krum- 
met og noget kortere end Fodleddet. Af Bikloer er der, 
ligesaalidt som hos foregaaende Art, det mindste Spor at 
opdage. 
De ydre vEgmasser (se Fig. 4) forholder sig som hos 
foregaaende Art. 
Dyrets Farve er mere eller mindre intens gul, gaaende |[ 
hos seldre Individer over til gulbrunt. 
Forekomst. Denne Art synes ved vore Kyster at 
vsere sjeldnere end foregaaende. Jeg har taget den paa et 
Par Punkter ved vor Vestkyst, fremdelcs ved Lofoten og 
ved Finmarken lige til Vadso. Den forekommer under lig- 
nende Forhold som P. circularis og oftest samrnen med 
denne Art. 
Udbredning. Som foregaaende Art er den en ud- 
prseget nordlig Form og synes derfor ogsaa at naa sin kraf- 
tigste Udvikling i de arktiske Have. Foruden ved Norge 
er den noteret fra Grordand (Kroyer) og den murmanske 
Kyst (Jarzynsky). Et enkelt Exemplar har jeg havt Anled- 
ning til at under soge fra det Kariske Hav, taget under 
Nordenskjolds Expedition. Derimod er den hverken obser- 
veret ved Danmark, de britiske 0er eller Ostkysten af 
Nordamerika. 
to that of the preceding species. The fingers are, however, 
without a trace of the fine teeth on the inner edge found 
in young specimens of that species, and have the points a 
little more incurvate. 
The false legs are appreciably longer than in the pre- 
ceding species, those of the female (see fig. 4 a) attaining 
about the length of the body, those af the male (fig. 4) con- 
siderably exceeding it, and furnished, as in the preceding 
species, with a conical lobe at the end of the 5th joint. 
The 4 outer joints are armed along the inner edge with a 
regular series of serrate spines (see fig. 4 e). The terminal 
claw is relatively longer than in P. circularis, and has se- 
veral teeth on the inner edge. 
The ambulatory logs (see fig. 4) are distinguished 
by their great length, nearly 4 times as great as that 
of the body. They are everywhere beset with spiniform 
setous processes, a good deal smaller however than in the 
preceding species, and quite smooth on the edges. Of 
the coxal joints, the 2nd is much elongated, considerably 
exceeding in length the 2 others taken together. The 
femoral joint in the female is a good deal swollen in the 
middle, in the male (fig. 4) much more slender and some- 
what arcuate. The 1st tibial joint is about the length of 
the femoral joint, whereas the 2nd is appreciably longer 
and very narrow. The tarsal joint' (see fig. 4 f) is somewhat 
larger than in the preceding species, obliquely truncate at 
the extremity, and armed on the inner edge with several 
spines, increasing in length outwards. The propodal joint is 
well-nigh straight, relatively narrower than in P. circularis, and 
armed on the inner edge with strong spines, the 4 or 5 
posterior of which are characterized by considerable size. 
The terminal claw is powerfully developed, falciform curvate, 
and somewhat shorter than the propodal joint. As in the 
preceding species, no trace of auxiliary claws can be detected. 
The outer egg-masses (see fig. 4) as in P. circularis. 
The colour of the animal is a more or less vivid yel- 
low, in aged specimens changing into yellowish-brown. 
Occurrence. On the coast of Norway this species 
would seem to be rarer than the preceding one. I have 
taken it in one or two localities on the West Coast, also at 
Lofoten and on the jcoast of Finmark as far as VadsO. 
It is met with under the same conditions as P. circularis 
and most frequently in company with that species. 
Distribution. Like the preceding species, this is a 
well-marked Northern form, and would also, therefore, appear 
to attain its greatest development in the Arctic Seas. Be- 
sides Norway, the animal has been recorded from Greenland 
(K rover), and the Murinan Coast (Jarzynsky), and 1 have 
also bad an opportunity of examining a single specimen 
from the Kara Sea, taken on Nordenskjald’s Expedition. 
On the other hand it has not been observed either on the 
coasts of Denmark or those of the British Islands; nor has 
it been recorded from the eastern coast of North America.
