derkanten af (lenne Finger Andes en temmelig lav lamelle- 
formig Udvidning, der fortil, strax indenfor Fingrenes Spids, 
danner et vinkelformigt Fremspring. Derimod er Inder- 
kanten af den bevregelige Finger ganske glat. 
Nedenfor Saxlennnemes Insertion benuerkes (se Fig. 
3 a) hos alle de undersagte Exeraplarer til liver Side et 
lidet knudeformigt Fremspring. Da disse Fremspring netop 
er beliggende der, hvor hos andre PycnogOnideer Folerne 
pleier at vaere fmstede, er der al Grand til at anse deni 
for et ubetydeligt Rudiment af disse Lemmer. Hos ingen 
af de 2 ovrige Arter liar jog kunnet opdage det mindste 
Spor af disse Knuder. 
De falske Fodder forholder sig, som hos de 2 ovrige 
Arter, noget forskjelligt hos de 2 Kjtm, idet de hos Han- 
nen (Fig. 3 d) er betydclig lamgere end hos Hunnen (Fig. 
3 c), livad der isser skyldes den stserkere Udvikling af ote 
Led, ved hvis Ende den sasdvanligo borstebesatte Lap fore- 
findes. De ydre Led stemmer, i Henseende til det ind- 
byrdes Lamgdeforhold, temmelig noie overens med sanime 
hos foregaaende Art. Derimod viser de laterale Toinei 
et meget afvigeudo Udseende. De er nemlig (se Fig. 3 1) 
for det forste forholdsvis meget storre og tykkere, bredt 
laneetformige, og dernmst mangier de ganske Saugtakker, 
idet Randen kun viser et uregelmaessigt bolgefornngt 
Forlob. 
Gangfodderue (se Fig. 3) viser en temmelig robust 
Bygning, men er betydelig stserkere forlsengede end hos den 
typiske Art. nsesten 4 Gange liengere end Legemet, og ad- 
skiller sig ogsaa i Detaillerne meget bestemt fra sannne 
hos begge de ovrige Arter. De er overalt tiet besatte med 
meget smaa, naisten mikroskopiske Haar, der giver dem et 
fint loddent Udseende. Hoftepartiet er her forholdsvis 
kort, neppc lamgere end Bredden mellem de midterste hide- 
I'ortsatser, og Forskjellen i Lmngde mellem dets 3 Led 
mindre end hos de 2 ovrige Arter, Laarleddet er derimod 
meget stierkt forlamget, omtrent 2 1 /* Hang lamgere end 
Hoftepartiet, og er hos Hunnen, som sredvanlig, tykkere 
end hos Hannen. lste Laegled er kjendelig kortere end 
Laarleddet, medens 2det Lregled, som smdvanlig, or det 
lmngste af alle. Tarsalleddet (se Fig. 3 g) or forholdsvis 
betydelig storre end hos de 2 foregaaende Arter, lamgere 
end bredt og successivt noget udvidet mod Enden. Der- 
imod er Fodleddet forholdsvis mindre kraftigt ndviklet, 
neppe mere end dobbelt saa langt som Tarsalleddet, og 
noget afsmalnende mod Enden. Det er i Inderkanten be- 
vrnbnet med circa 5 storre Turner, hvoral 1 or fmstet om- 
trent i Midten, de ovrige mermere Basis. Endekloen er 
stserkt forlamget, vel saa lang som Fodleddet, komskt til- 
spidset og mindre stierkt krummet end hos de 2 ovrige 
Arter. 
Farven er i levende Tilstaud omtrent som hos C. mal- 
leolata, nemlig ensformig hvidgul. 
Forekomst og Udbredning. Ved vqre Kyster liar 
jeg kun observeret nservaerende Art paa et eneste Punkt, 
nemlig ved Vadso, hvor jeg for mange Aar siden tog et 
a distinct although slight incurvation. On the inner edge 
of this linger a rather low lamelliform expansion occurs, 
which, anteriorly, just within the point of the fingers, con- 
stitutes an angular projection. The inner edge of the mo- 
bile finger is, on the contrary, quite smooth. 
Below the insertion of the chelifori was found (see 
fig. 3 a), in all the specimens examined, on either side; 
a small tuberculiform projection. Those projections being 
located just where the palpi in other Pyenogonidea occur, 
| there is every reason to regard them as a trifling rudiment 
of these limbs. In neither of the 2 other species have I 
succeeded in discovering the slightest trace of the said 
projections. 
The false legs deviate somewhat, as in both the other 
species, in the 2 sexes, those of the male (fig. 3 d) being 
considerably longer than those of the female (fig. 3 c), 
mainly arising from the greater development of the 5th 
joint, at whose extremity the usual setiferous lobe occurs. 
The outer joints agree, as to their mutual relative propor- 
tions in length, rather closely with those of the preceding 
species. On the other hand, the lateral spines exhibit a 
very different appearance. They are (see fig. 3 1 ), in the first 
place, relatively much larger and thicker, broadly lanceolate, . 
and, in the second place, they are totally destitute of saw- 
teeth, the edge simply exhibiting an irregular, undulatory line. 
The ambulatory legs (see fig. 3) exhibit a rather 
robust structure but are much more elongate than in the 
typical species, attaining well-nigh 4 times the length ol 
the body, differing, too, in several details, very decidedly, 
from those in both the other forms, they are everywhere 
densely beset with very minute, almost microscopic hairs, 
which gives them a delicate downy appearance. The coxal 
part in this animal is relatively short, hardly longer than 
the breadth between the mesial lateral processes, and the 
difference in length between its 3 joints is less than in the 
2 other species. The femoral joint, on the other hand, is 
very much elongated, about two and a halt times longth 
than the coxal part, and, as usual, thicker in the female 
than in the male. The 1st - tibial joint is appreciably 
shorter than the femoral one, whilst the 2nd tibial joint 
is, as usual, the longest of all. The tarsal joint (see fig. 
3 g) is, relatively, a good deal larger than in the 2 preceding 
species, and somewhat gradually expanded towards the end. 
On the other hand, the propodal joint is relatively less 
powerfully developed, hardly more than twice as long as the 
tarsal joint, and tapers a little towards the extremity. It 
is armed on the inner edge with about 5 largish spines, 
one of which is affixed near the middle, the others nearer 
the base. The terminal claw is much elongated, rather longer 
than the length of the propodal joint, conically acuminated, 
and less sharply curved than in the 2 other species. 
The colour is, in the live state, about as in C. 
malleolata, viz., a uniform whity yellow. 
Occurrence and Distribution. On the coasts of Nor- 
way, I have observed the present species in but one local- 
ity, viz. at Vadso. where, many years ago, I took a soli-
