sserdeles lang, udprseget lef'ormig, med Inderkanten tilskjser- 
pet og Enden gaaende ud i en sylskarp Spids ; Bikloerne, 
som hos foregaaende Art, yderst smaa og rudimentsere, ikke 
fremragende foran Endekloens Y derkant, 
Integumenterne er temmelig tykke, men boielige og 
riser under Mikroskopet en fint granuleret Structur. 
Legemet er af hvidagtigFarve og halvtgjeunemskinneride, 
saa at Here af de indre Dele skimtes mere eller mindre 
tydeligt igjennem Huden. Sees Dyret fra Bugsiden (big. 
3 c), riser saalodes Buggangliekjmden sig tenimelig tydeligt; 
den bestaar, som hos de orrige til denne Familie horende 
Former, kun af 4 Ganglier, idet det forreste Ganglion 
mangier eller rettere er sammensmeltet med det folgendc. 
Forekomst. Det orenfor beskrevne Exemplar toges 
red Magero, sondenom Trpndhjemsfjorden, paa et Dyb af 
ca. 1 00 Fame. 
Fain. 3. Pallenidse. 
Character. Saxlemmer vel udriklede; Folere mang- 
lende ; falske Fodder tilstede hos begge Kjon. 
Bemserkninger. Ved de ovennfevnte Characterer er 
denne Familie vel skilt saavel fra foregaaende som efterfpl- 
gende Familie, imellem hvilke den liar sin naturlige Plads. 
Fortiden de 3 i det folgende nairmere omtalte Slsegter, 
horer herhen ogsaa den af Dohm opstillede Slaigt Nuopal- 
lene, hos hvem et Rudiment af Folere er tilstede. End- 
ridere tror jeg, som allerede ovenfor benuerket, at Here at 
de af Hoek som Phoxichilidier beskrevne Former fra Chal- 
lenger Expeditionen rettest bor hen fores til denne Familie 
og indordnes under en eller Here nye Slsegter. Hvad ende- 
lig de 3 af sidstnaivnte Forfatter, ligeledes fra Challenger 
Expeditionen, beskrevne Pattern - Arter angaar, saa synes 
mig ingen af dem rigtigt at ville passe ind under nogen at 
de 3 nordiske Slsegter, og, da de ogsaa indbyrdes viser 
ikke ubetydelige Forskjelligheder, skulde jeg vsere mest til- 
boielig til at antage, at de repraesentgrer 3 nye Slaegtstyper 
henhorende til nservserende Familie. 
Gen. 5. Pallene, Johnston 1837. 
Slaegtseharacter. Legemet glat, mere ellei mindre 
smalt, cylindriskt, med vel adskilte Sidefortsatser. Hoved- 
segmentet forholdsvis stort, med tydelig Hals og stmrkt ud- 
videt Paudedel. De to sidsto Kropssegmenter sammensmel- 
tede med hinanden. Halesegmentet meget lidet, stumpt ko- 
niskt, opadrettet. Gieknuden mere eller mindre ophoiet, 
margin exhibits a regular series of short, anteriorly curv- 
ing spines, 18 — 20 in number. The terminal claw is exceed- 
ingly long, distinctly falciform, with the inner margin shar- 
pened and produced at the extremity to an awl-like point ; 
the auxiliary claws, as in the preceding species, exceedingly 
small and rudimentary, not projecting beyond the outer 
margin of the terminal claw. 
The integuments are rather thick, but flexible, and ex- 
hibit under the microscope a fine, granular sculpturing. 
The body is whitish in colour and semi-translucent, 
so that several of the inner parts are seen, more or less 
distinctly, shining through the integument. Viewed from the 
ventral side (fig. 3 c), the animal accordingly exhibits, 
pretty distinctly, the ventral chain of ganglia; the latter 
consists, as in the other forms belonging to this family, 
of but 4 ganglia, as the foremost ganglion is wanting, or 
rather is fused into that succeeding it. 
Occurrence. The specimen described above was taken 
at Magero, south of the Throndlijemsfjord, from a depth 
of about 100 fathems. 
Fain. 3. Pallenidae. 
Character. Chelifori well developed ; palpi wanting or 
rudimentary; false legs present in both sexes. 
Remarks. By the above given characters this family 
is well distinguished, both from the preceding and the suc- 
ceeding one, between which it has its natural place. Ex- 
clusive of the 3 genera spoken of more at large in the 
sequel, to this family also belongs the genus etablished by 
Dohrn, Nespallene, in which, a rudiment of palpi is present. 
Moreover, 1 certainly think, as already noticed above, that 
several of the forms from the Challenger Expedition, des- 
cribed by Hoek as Phoxichilidians, should properly be refer- 
red to this family, and be classed under one or more new 
genera. Finally, as to the 3 Pallene species from the 
Challenger Expedition, likewise described by that author, 
none of them, it seems to me, can strictly be ranked under 
any of the 3 Northern genera; and exhibiting as they do 
differences by no means trifling, I am most inclined to 
regard them as representing 3 new generic types belonging 
to the present family. 
Gen. 5. iPallene, Johnston 1837. 
Generic Character. Body smooth, more or less slen- 
der, cylindrical, with well separated lateral processes. Ce- 
phalic segment comparatively large, with neck distinct and 
frontal part prominently expanded. The two last segments 
of the trunk coalescent. Caudal segment very small, obtusely 
conic, directed upwards. Oculiferous tubercle more or less
