De til de falske Fødder hos Hannen fæstede Æg er
forholdsvis betydelig mindre og talrigere end hos foregaaende
Slægt og danner 2 afrundede Masser, hver omgiven af en
fælles Membran.
Dyrets Farve er i levende Tilstand gulagtig, hos ældre
Individer næsten gulbrun. Men ofte er Legemet saa tæt
besat med tremmede, til de talrige pigiormige Fortsatser
heftende Dele, at baade Legemets Fonn og Farve er
vanskelig at observere.
Forekomst. Jeg har taget denne Art paa flere
Steder af vor Vestkyst og nordlig lige til Vadsø. Den synes
alene at forekomme paa forholdsvis grundt Vand, fra 6—20
Favne, mellem Alger og Hydroider.
Udbredning. Arten synes idethele at maatte betragtes
som en udpræget nordlig Form. Foruden ved Norge er den
nemlig af Krøyer noteret fra Grønland, af Wilson ira
Nordamerikas Østkyst, af Jarzynsky fra den murmanske Kyst
og af Dr. Hansen fra Novaja Zemljas Sydvestkyst.
Good-sirs Exemplarer var fra Kysten af Skotland.
The ova attached to the false legs in the male are,
relatively, a good deal smaller and more numerous than in the
preceding genus, and form 2 rounded masses, each enveloped
in a common membrane.
Colour of the animal in the living state yellowish, in
aged specimens well-nigh yellowish-brown. Otten, however,
the body is so densely beset Avith extraneous substances
adhering to the numerous spiniform projections, that both
the form and colour of the body are difficult to recognise.
Occurence. 1 have taken this species in several
localities on the West Coast of this country and as lar north
as Vadsø. It would seem to occur only in comparatively
shallow water — from 6 to 20 fathoms — among Algæ and
Hydroidæ.
Distribution. The species should, it would appear,
on the whole, be regarded as a well-marked Northern torm.
Besides from Norway, it is mentioned by Krøyer trom
Greenland, by Wilson from the east coast of North America, by
Jarzynsky from the Murinan Coast, and by Dr. Hansen from
the south-west coast of Novaja Zemlja. Goodsir’s specimens
were from the coast of Scotland.

Artscharacter. Legemet forholdsvis mindre
undersætsigt end hos P. circularis, med Sidefortsatserne videre
skilte og piggede i Enden. Rygsiden af Kroppen glat, uden
pigformige Fortsatser. Hovedsegmentet noget længere end
de 3 følgende tilsammen, med tydelig, skjøndt kort Hals,
Pandedelen stærkt fortykket og oventil ved Enden bevæbnet
med korte Torner. Halesegmentet noget opadrettet, kortere
end hos P. circularis. Øieknuden særdeles lav, tilrundet.
Snabelen stærkt nedadrettet, af samme Beskaffenhed som
hos foregaaende Art. Saxlemmerne hos fuldvoxne Individer
meget store, Skaftet cylindriskt med flere tornformige
Fortsatser oventil, Haanden længere end Skaftet, nedadrettet,
successivt udvidet mod Enden, Fingrene meget korte, stærkt
indadrettede, begge med et knudeformigt Fremspring i
Inderkanten og stumpt afrundet Spids. De falske Fødder hos
Hannen længere end Legemet, de 4 ydre Led forsynede
med en regelmæssig Rad af saugtakkede Torner.
Gangt’ød-derne stærkt forlængede, næsten 4 Gange læugere end
Legemet og bevæbnede med talrige, forholdsvis smaa, glatte
pigformige Fortsatser, hver med en Børste i Spidsen;
Fodleddet forholdsvis smalere end hos P. circularis, med 4
stærke Torner i det bagre Parti af Inderkanten; Endekloen

Specific Character. Body relatively less thickset
than in P. circularis, with the lateral processes farther apart,
and spinous at the extremity. Dorsal surface of trunk smooth,
without spiniform projections. Cephalic segment somewhat
longer than the 3 succeeding ones taken together, with
distinct, although short neck, trontal part much tumificated and
armed above, at the end, with short spines. Caudal
segment directed a little upwards, shorter than in P.
circularis. Oculiferous tubercle exceedingly low, rounded.
Proboscis pointing strongly downwards, similar in character
to that of preceding species. Chelifori in full-grown
specimens very large, scape cylindrical with several spiniform
projections above, hand longer than scape, directed
downwards, expanding gradually towards the extremity; fingers
very short, directed greatly inwards, both with a nodular
projection on the inner edge and an obtusely rounded
point. False legs in male longer than the body, the
4 outer joints furnished with a regular series of serrate
spines. Ambulatory legs much elongated, almost 4 times as
long as body, and armed with numerous, comparatively small
and smooth spiniform projections, each bearing a bristle at
the point; propodaljoint relatively slenderer than in P. circu-
