2 Exemplarer, et gauske uiigt Individ og on fuldvoxen Hun,

Arten er en segte arktisk Form.

Bemserkninger. I den Bcgramdsniug, hvori Familien 
her tages, nemlig kun omfattende den tidligere Slsegt Nym- 
ph on, or den hovedsageligt character iseret ligeovorfor de i 
det foregaaende omtalte Familier ved Tilstedevmrelsen af 
vel udviklede Folere, og fra de folgende Familier dels ved 
disse Lemmers Structur, dels ved den kraftige Udvikling 
af Saxlemmerno. Familien slutter sig i Henseende til Here 
Bygningsforhold nsermest til Fain. Pattenidw, uden at jeg 
dog finder at kunne forbinde begge til en Familie, saaledes 
som af enkelte Forskere gjort. Paa den an den Side liar 
jeg troet at burde oplose den tidligere Skogt Nymphon i 3 
Skegter, og jeg antager det ikke for usandsynligt, at man 
ved et noiore Kjendskali til de herhen liorende Former vil 
finde det nedvendigt at gaa endnu videre i denne Retning. 
Gen. 8. Nymphon, Fabr. 1794. 
Slregtseharaeter. Legemot glat, mere eller min- 
dre smalt, cylindriskt, med vel sondrede Sidefortsatser. 
Hovedsegmentet temmelig stort, med vel markeret Hals og 
noget udvidet Pandedel. Halesegmentet forholdsvis lidet, 
cylindriskt, opadrettet. 0ieknudeu mere eller mindre op- 
hoiet, Lindserne af ens Storrelse og beliggende nmrmere 
Basis af 0ieknuden. Snabelen forholdsvis stor. fortilrettet. 
cylindrisk, glat, afrundet i Enden. Saxlemmerne kraftigt 
udviklede, Haanden forholdsvis smal, Fingrene ssedvanlig 
kortere end Palmen, konisk tilspidsede og fint tandede i 
Inderkanten. Fglerne af middelmaadig Laengdo, lste Led 
meget lidet, de 2 sidste feet borstebesatte og dannende med 
foregaaende Led en mere eller mindre udprseget Yinkel. 
De falske Fodder 10-leddede, sparsomt borstebesatte, 4de 
og ote Led hos Hannen staerkt forhengede og tynde, de 4 
ydre Led med en regelmaessig Rad af saugtakkede Torner, 
Endekloen vel udviklet, tandet i Inderkanten. Gangfqddorne 
ssedvanlig staerkt forlaengede og spinkle, sparsomt haarede, 
2det Laegled laengst, Tarsalleddet mere eller mindre forlaen- 
get, Fodleddet ssedvanlig linesert, Endekloen med tydelige 
Bikloer. De ydre ASggemasser hos Hannen kugleformige, 
tary example, a full-grown male, from a depth of about 100 
fathoms; clay bottom. The species also occurs, however, in 
tlie Kara Sea, whence I have had 2 specimens for examina- 
tion, a quite young individual and a full-grown female, col- 
lected on Nordenskj old’s Expedition from a depth of 50 
fathoms. Hence, it appears, with considerable certainty, 
that the species is a true Arctic form. 
Fam. 4. Nymphonidse. 
Characters. Chelifori and palpi well developed, the 
latter five-jointed. False legs present in both sexes. 
Remarks. In the restricted sense in which the family 
is spoken of here, comprising merely the earlier genus Nym- 
phon, it is characterised, as compared with the previously 
mentioned families, by the presence of well-developed palpi, 
and from the subsequent families, partly by the structure of 
these limbs and partly by the powerful development of the 
chelifori. The family approximates closest, in certain struc- 
tural peculiarities, to the family Pctllenidce. Without affording, 
in my judgment, sufficient reason to combine them into one 
family, as has been done by some naturalists. On the 
other hand, I have seen fit to break up the earlier genus, 
Nymphon, into 3 genera, and think it not improbable, that 
a more intimate acquaintance with the forms in question 
will show the necessity of going still farther in that di- 
rection. 
Gen. 8. Nymphon, Fabr. 1794. 
Generic Character. Body smooth, more or less 
slender, cylir.dric, with well-defined lateral processes. Ce- 
phalic segment rather large, with well-marked neck and 
somewhat expanded frontal part. Caudal segment compa- 
ratively small, cylindric, directed upwards. Oculiferous 
tubercle more or less elevated, the lenses equal in size, and 
located nearer to the base of the oculiferous tubercle. 
Proboscis comparatively large, anteriorly directed, cylin- 
dric, smooth, rounded at the extremity. Chelifori powerfully 
developed, hand comparatively narrow, fingers as a rule 
shorter than palm, conically acuminated, and finely dentate 
on the inner margin. Palpi of moderate length, 1st joint 
very small, the 2 last densely setiferous and forming 
with the preceding joint, a more or less prominent 
angle. False legs ten-jointed, sparingly beset with bristles, 
4th and 5th joints in male very elongate and slender, the 
4 outer joints with a regular series of serrated spines, term- 
inal claw well developed, dentated on the inner margin. 
Ambulatory legs as a rule exceedingly elongate and slender, 
sparingly bristle-beset, 2nd tibial joint longest, tarsal joint 
more or less prolonged, propodal joint usually linear,
