dybest og afrundet i Bunden. Fortil danner Haanden lige 
over den kraftige Endeklo et spidst Fremspring. 
Gjellebladene, Brystposen og de 3 bagre Fodpar riser 
intet udmierkende i sin Bygning. 
Af de 2 Par Bagkropslemmor er det forreste (se Fig, 
5 c) tydeligt 2-leddet og betydelig stprre end det bagerste, 
der kun danner et Par simple, i Kanterne tint cilierede 
koniske Vedhseng. 
Hcmnen (Fig. 5 x) er betydelig stprre end Hunnen 
og af noget mere langstrakt Kropsform. De 2 forreste 
Segmenter viser dog ikke noget saadant anomalt Forhold 
som hos Hannerne af foregaaende Slsegt. Hvad Legemets 
Bevffibning angaar, saa er den noget ulig sapime hos Hun. 
nen, idet de dorsale Pigge er betydelig mindre fremtrmdende, 
hvorimod hole Legemets Overflade, ligesom ogsaa en stor 
Del af Lemmerne, er ru af talrige smaa tilspidsede Knuder. 
lste Par Folere er stserkere forlsengede end hos Hun- 
nen og navnlig Skaftet kraftigere udviklet, medens Svoben 
synes at vaere forholdsvis kortere. 
2det Fodpar skiller sig i sin Bygning fra samme hos 
Hunnen alone derved, at Basalleddet er noget steerkere 
forlaenget, medens Haanden viser npiagtig samme Form. 
Hele dette Fodpar er, ligesom lste Par Foleres Skaft, feet 
besat med de ovenomtalte Smaaknuder. 
Bagkroppen med dens Yedhseng (Fig. 5 c) skiller sig 
heller ikke i nogen vaesentlig Grad fra samme hos Hunnen. 
Foran den. udgaar fra 'sidste Forkropssegment de 2 ydre 
Kjpnsvedhreng, der er af et lignende Udseende som hos 
Hannen af Caprella spinosissima. 
Legemet er hos begge Kjon temmelig gjennemsigtigt, 
hvidagtigt, med uregelmaessige morkere Pigmentshatteringer. 
Lsengden af den segbserende Hun er 30’"". Hannen 
er betydelig storre og opnaar en Lrengde af indtil 38””’. 
Forekomst og Udbredning. Denne smukke og char- 
acteristiske Art er under Expeditionen observeret pan 2 
forskjellige langt fra, hinanden liggende Stationer; den ene 
(Stat. 48) beliggende i Havet 0st af Island, den anden 
(Stat. 336) ndenfor Sydpynten af Spitsbergen ; Dybden fra 
70 til 299 Favne. Af disse Stationer tilhorer ialfald den 
ene (Stat. 48) den kolde Area, og don anden ligger under 
en saa hoi nordlig Brede, at Artens jarktisko Oprindelse 
neppe er tvivlsom. 
Angaaende dens geographiske Udbredning ndenfor 
Nordhavet, saa er den observeret saavel ved Gronland som 
ved Nordamerikas 0stkyst, nordenom Cap Cod. 
lappets, the foremost is the deeper, and rounded off at the 
bottom. Anteriorly, just above the powerful terminal claw, 
the hand extends forward as a pointed prolation. 
The branchial scales, the marsupium, and the 3 pos- 
terior pairs of legs exhibit nothing characteristic in their 
structure. 
Of the 2 abdominal appendages, the anterior (see fig- 
5 c) is distinctly two-jointed, and much larger than the 
posterior, which constitutes merely a pair of simple appen- 
dages finely ciliated along tiie margins. 
The Male (fig. 5 x) is considerably larger than the 
female, and somewhat more elongate in form. The 2 an- 
terior segments do not, however, exhibit any such anomalous 
relation as in the males of the preceding genus. With 
regard to the armature of the body, it differs somewhat 
from that in the female, the dorsal spikes being much less 
prominent, whereas the whole surface of the body, as also 
a considerable portion of the limbs, are rough from numerous 
small acute protuberances. 
The 1st pair of antennae are more elongate than in 
the female, with the peduncle exhibiting a specially powerful 
development, whereas the flagellum would appear to be 
relatively shorter. 
The 2nd pair of legs differ in structure from that 
in the female simply by the basal joint occurring a trifle 
more elongate; but the hand exhibits precisely the same 
form. The whole of this pair of legs, as also the peduncle 
of the 1st pair of antennse, are densely beset with the fore- 
mentioned small protuberances. 
Nor does the abdominal division of the body with 
its appendages (fig. 5 c), present any essential difference 
from that in the female. Anterior to it, issue from the 
last body-segment the 2 outer generative appendages, of 
a similar appearance to those in the male Caprdla spi- 
nosissima. 
The body is *in both sexes well-nigh translucent, whit- 
ish, with irregular pigmentary shadings. 
Length of the ovigerous female 30"”. The male is 
considerably larger, attaining in length 38””. 
Occurrence and Distribution. — This beautiful and 
characteristic species was met with on the Expedition at 2 
widely distant Stations; the one (Stat. 48) lay east of Ice- 
land, the other (Stat. 336) was located off the southern 
extremity of Spitzbergen; depth ranging from 70 to 299 
fathoms. Of these Stations, one at least (Stat. 48) belonged 
to the cold area, and the other was located in so high a 
latitude, that the Arctic origin of the species can hardly 
be doubtful. 
As regards its geographical distribution without the 
limits of the Northern Ocean, the animal has been observed 
off Greenland and the eastern coast of North America, 
north of Cape Cod.
