Hannen er dette Led (se Fig. 3 i) som smdvanlig betydelig 
smalere og har i den indre Kant 4—5 afrundede Knuder. 
2det Ltegled er meget smalt, mesten linerert, og omtrent 
2 1 / a Gang lsengere end det terminale Afsnit. Dette sidste 
(se Fig. 3 h) skiller sig kjendeligt fra samme lios de 2 
foregaaende Arter og er idethele betydelig spinklere. r lar- 
salleddet er mere end dobbelt saa langt som bredt og kun 
ganske svagt udvidet mod Enden. ' Fodleddet er stserkt 
forlsenget, omtrent 2 1 / a Gang lsengere end Tarsalleddet, 
meget smalt, linesert, og langs Inderkanten bevsebnet med 
en Rad a.f 12 — 16 temmelig ulige ndviklede Torner. Ende- 
kloen er noget mere end halvt saa lang som Fodleddet og 
stsei’kt krummet ved Basis. Bikloerne er, i Modssetning 
til hvad Tilfseldet er hos den typiske Art, vel udviklede 
og nsesten af Kloens halve Lsengde. 
De ydre ^Egmasser (se Fig. 3 b) er forholdsvis mindre 
end hos foregaaende Art, kugleformige, og indeholder et 
forholdsvis ringe Antal nalmindelig store -ZEg. 
Dyrets Farve er blegt gulagtig, med brunlig gjennem- 
skinnende Tarmsystem. 
Forekomst. Jeg har taget denne Art af og til ved 
vor Vestkyst, fra Hoiden af Stavanger til Tjoto i Nord- 
land. Yed Finmarken har jeg derimod ikke observeret 
den, og heller ikke under Nordbavs-Expeditionen erholdtes 
denne Art. 
Udbredning. Foruden ved Norges Kyster er den 
alene med Sikkerhed kjendt fra de Britiske 0er (Goodsir). 
Den har saaledes utvivlsomt en mere sydlig Udbredning 
end de dvrige Arter af Slsegten.

Artscharacter. Legemet forholdsvis betydelig spinklere 
end hos de 3 foregaaende Arter, Kroppen nsesten cylindrisk, 
oventil kort og tint haaret, med Sidefortsatserne vel adskilte. 
Hovedsegmentet neppe lmngere end tie 2 fslgende Segmenter 
tilsammen; Halsen kort, Pandedelen successivt udvidet. 
Halesegmentet simpelt cyliudriskt, stumpt afrundet i Enden. 
0ieknuden stump konislt, lige opadrettet, med forholdsvis 
store Lindser. Snabelen noget kortere end Hovedseg- 
mentet, horizontal, noget afsmalnende. Saxlemmeine noget 
lig samme hos Ch. spinosim, men med Haanden forholdsvis 
kortere og Fingrene mindre spinkle. Fqlerne temmelig 
forkengede, 2det og 3die Led omtrent af samme Lamgde, 
sidste Led neppe kortere end nsestsidste og begge tilsam- 
men lig 3die. De falske Fodder hos Hannen temmelig 
spinkle, 5te Led successivt udvidet mod Enden og her 
kort haaret; Kandtornerne forholdsvis smaa, stumpt lancet- 
large egg-cells. In the male, this joint (see fig. 3 i) is, as 
usual, considerably narrower, and has on the inner edge 
4 or 5 rounded nodules. The 2nd tibial joint is very 
narrow, well-nigh linear, and about 2 */s times longer than 
the terminal section. The latter (see fig. 3 h) is appreci- 
ably distinguished from that part in the 2 preceding 
species, and is, on the whole, considerably more slender. 
The tarsal joint is more than twice as long as it is broad, 
and but very slightly expanded towards the extremity. 
The propodal joint is much elongated, about 2 1 / 2 times 
longer than the tarsal joint, very narrow, linear, and armed 
along the inner edge with a series of 12 — 16 rather un- 
equally developed spines. The terminal claw is somewhat 
more than half as long as the propodal joint, and sharply 
curved at the base. The auxiliary claws, contrary to 
what occurs in the typical species, are well developed, 
and almost half the length of the claw itself. 
The outer egg-masses (see fig. 3 b) are smaller, 
relatively, than in the preceding species, globular in form, 
and contain a comparatively small number of uncommonly 
large ova. 
The colour of the animal is a pale yellow, with 
brownish intestinal system shining through the skin. 
Occurrence. I have now and again taken this species 
on the West Coast of Norway, from the latitude of Stav- 
anger to Tjoto in Nordland. On the Coast of Finmark 
I have, on the contrary, not observed it, nor was the 
animal obtained on the . North-Atlantic Expedition. 
Distribution. Besides on the Coasts of Norway, the 
species is only known with certainty from the British Is- 
lands (Goodsir). It has thus, unquestionably, a more south- 
erly distribution than the other species of the genus.

Specific Characters. Body relatively much more' 
slender than in the 3 preceding species, trunk well-nigh 
cylindric, short and finely hirsute above, with the lateral 
processes well separated. Cephalic segment scarcely 
longer than the 2 following segments taken together; neck 
short, frontal part successively expanded. Caudal segment 
simple-cylindric, obtusely rounded at the extremity. Ocul- 
iferous tubercle obtuse-conic, pointed straight upwards, 
with comparatively large lenses. Proboscis somewhat 
shorter than the cephalic segment, horizontal, slightly 
tapering. Chelifori somewhat like those of Civ. spinosim, 
but with the hand relatively shorter and the fingers less 
slender. Palpi rather elongated, 2nd and 3rd joints of 
about uniform length, last joint scarcely shorter than the 
penultimate one, and both taken together equalling the 
3rd. False* legs in the male rather slender, 5th joint
