agtige Integumenter sig forsynede med talrige smaa
ellips-oidiske Legemer (se Fig. 2 d).
Øieknuden har Formen af et høit. koniskt tilspidset
og lidt foroverbøiet Fremspring (se Fig. 2 c), der. som
hos foregaaende Art. mangler ethver t Spor af Pi ginent
eller Synselementer.
Snabelen (se Fig. 2 a. 2 b. 2 c) er vel saa lang som
den øvrige Del af Legemet, naar Halesegmentet fraregnes,
og lige fortilstrakt, nøiagtig i Kroppens Axe. Den er af
smal cylindrisk Form. neppe bredere end Kroppen, og har
paa Midten en svag men tydelig Opsvulmning. Spidsen
er noget skraat afstumpet, med den øvre Læbedel skydende
noget udover de 2 øvrige (se Fig. 2 b). Selve
Mundaab-ningen har et lignende Udseende som hos foregaaende Art.
Af Saxlemmer var hos ingen af de indsamlede
Exemplarer nogetsomhelst Spor at opdage. Det maa imidlertid
her anmærkes, at Hoek hos 3 af de 8 under Tritons
Expedition indsamlede Exemplarer fandt tydeligt udviklede
og temmelig stærkt forlængede, skjøndt overordentlig tynde
Saxlemmer, og at efter samme Forsker disse Lemmer ogsaa
var tilstede hos et Exemplar af den nærstaaende Art, C.
gracilis. Rimeligvis har ingen af disse saaledes udrustede
Exemplarer været fuldt udviklede. Det er imidlertid hoist
mærkværdigt, at disse Lemmer, der er fælles for alle
Pyc-nogonideer i Larvelivet, her bibeholdes og udvikles videre
lige til Dyret paa det nærmeste er udvoxet, for saa ganske
at forsvinde. Hvorvidt dette gjælder hlot de 2 her nævnte
Arter eller samtlige Arter af Slægten, er endnu ikke
tilstrækkelig oplyst.
Folerne (se Fig. 2 a, 2 b, 2 c) er i alt væsentligt
af en lignende Beskaffenhed som hos foregaaende Art og,
lige udstrakte, næsten 1/ä Gang længere end Snabelen.
Leddenes indbyrdes Længdeforhold stemmer ogsaa idethele
temmelig vel overens med samme hos hin Art, naar
undtages de 3 sidste Led. Af disse er nemlig (se Fig. 2 e)
det lste Led ualmindelig kort, næsten skaalformigt, og
skraat afskaaret i Enden, dannende nedad en afrundet
fremspringende Lap, medens de 2 øvrige er af sædvanlig
Form og indbyrdes næsten af ens Størrelse, eller det
sidste lidt længere og smalere end næstsidste.
De falske Fødder (se Fig. 2 a) er spinkle og
forlængede, lige udstrakte betydelig længere end det hele
Legeme, og stemmer idethele i sin Bygning temmelig nøie
overens med samme hos foregaaende Art. 4de Led (er
dog her forholdsvis noget større og neppe kortere end 5te.
Gangfødderne (se Fig. 2) udmærker sig ligeledes ved
sin overordentlig spinkle og forlængede Fonn, idet de, lige
udstrakte, er mere end 3 Gange længere end Legemet. I
Henseende til det indbyrdes Længdeforhold af Leddene
eider imidlertid kun liden Forskjel mellem de 2 Arter, naar
alene undtages, at de 2 sidste Led (se Fig. 2 f) er af
ous integuments show themselves to be furnished with
numerous small ellipsoidal bodies (see fig. 2 d).
The ocular tubercle has the form of a high conically
pointed prominence bent slightly forward (see fig. 2 c),
which, as in the preceding species, is deficient in the
slightest trace of pigment or visual elements.
The proboscis (see fig. 2 a, 2 b, 2 c) is fully as long
as the rest of the body, when the caudal segment is
deducted. and. directed straight forward, lies exactly in the axis
of the trunk. It is narrow, cylindric in form, scarcely
broader than the trunk, and at the middle has a faint but
distinct tumefication. The point is somewhat obliquely
truncated, with the superior labial part projecting a little
beyond the 2 others (see fig. 2 b). The oral aperture
itself is similar in appearance to that of the preceding
species.
Of chelifori. there was not in any of the specimens
obtained a trace discoverable. It must be noted here,
however, that Hoek, in 3 out of the 8 specimens collected
during the ,.Triton’s" Expedition, observed distinctly
developed and pretty greatly elongated, although extremely thin
chelifori, and that according to the same naturalist those
limbs were also present in a specimen of the closely
related species C. gracilis. Probably none of the
specimens thus equipped have been fully developed. It is,
however, highly remarkable that those limbs, which are
common to all Pycnogonids in the larval state, are here
maintained and further developed until the animal is
almost fully grown, and then quite disappear. Whether
this is the case only with the 2 species named here, or
affects all species of the genus, is not yet sufficiently
elucidated.
The palpi (see figs. 2 a. 2 b, 2 c) are, in all
essential respects, similar in character to those of the
preceding species and, straightly extended, almost longer
than the proboscis. The mutual longitudinal relations of
the joints correspond, upon the whole, pretty well with
the same in that species, with the exception of the 3
last joints. Of these the 1st (see fig. 2 e), especially, is
uncommonly short, almost cupuliform, and obliquely
truncated at the extremity, forming downwards a rounded
prominent lobe, while the 2 others are of the usual form, and
mutually about equal in size, or the ultimate one perhaps
a little longer and narrower than the penultimate one.
The false legs (see fig. 2 a) are slender and elongate,
straightly extended considerably longer than the entire
body, and correspond in their structure, upon the whole,
pretty closely with the same features ill the preceding
species. The 4th joint is, however, relatively, somewhat
larger aud scarcely shorter than than the 5th.
The ambulatory legs (se fig. 2) distinguish themselves,
also, by their extremely slender and elongate form, as they,
straightly extended, are more than 3 times longer than
the body. In regard to the mutual longitudinal relations
of the joints, there is, however, only _little divergency
between the 2 species, with the exception, only, that the
