Beskrivelse. Legemets Liengde hos fuldvoxne Indi- 
vider er 10 wm , nied en Spandvidde af 80”™, og denne Art 
opnaar saaledes en meget anselig Storrelse, 
Legemsformen er idethele (se PI. IV, Fig. 3) tem- 
melig robust, og denne Art ligner i saa Henseende ved 
forste 0iekast mere den typiske Form end foregaaende Art. 
trods det at Gangfodderne er betydelig staerkere foi’liengede 
end hos bin. Selve Kroppen (se Fig. 3 a) viser en meget 
undersmtsig og sammentnengt Form, og Sidefortsatserne 
er derfor ogsaa kun skilte ved meget smale, spaltformige 
Mellamrum. Hovedsegmentet er forholdsvis betydelig miu- 
dre end hos de 2 foregaaende Arter, idet det paa langt 
user ikke opnaar Kroppens halve Lsengde, og Pandedelen er 
heller ikke saa stmrkt udvidet. Halsen er, i Modsaetning 
til hvad Tilfaaldet var hos foregaaende Art, her meget kort, 
selv betydelig kortere end hos den typiske Art, og mellem 
Pandedelen og de forreste Sidefortsatser er der derfor kun 
et lidet MeHenirum, soni til Siderne ganske udfyldes af 
Ledknuderne for de falsku Fodder. Halesegmentet er oin- 
trent af samme Udseende som hos C malleolata. 
Gieknuden er saerdeles lav og jevnt tilrundet saint ud- 
mairket ved den ringe Storrelse af Lindserne (so Fig. 3 b) ; 
disse er endnu videre skilte fra hinanden end hos C. mal- 
leolata og tydeligt grupperede 2 og 2 til liver Side, liver 
nied et forholdsvis lidet og skarpt begrsendset Pigmentbaiger. 
Snabelen (se Fig. 3 a) synes forholdsvis noget storre 
end hos de foregaaende Arter, idet den nmsten er af Ho- 
vedsegmentets Lsengde ; dens Bygning er forovrigt fuldkom- 
men som hos liine Arter. 
Saxlemmerne (se Fig. 3 a) er vistnok, sammenlignet 
med samme hos andre Pycnogonideer, temmelig kraftigt 
udviklede, men dog paa langt nser ikke i den Grad som 
hos den typiske Art, og selv hos foregaaende Art synes 
disse Lemmer i visse Henseender at vane mere robuste. 
Skaftet er ganske glat, cylindriskt, dog med Tderkanten 
noget indbuet ved Basis. Haandcn er langtfra saa staerkt 
opsvulmet som hos de 2 foregaaende Arter og derfor hel- 
ler ikke saa udpraiget kugleformig, men af noget uregel- 
nnessig sammentrykt Form. Den er overalt tret besat med 
saerdeles korte Haar, der henad den ubevaegelige Finger 
bliver noget. hengere, uden dog at antage den f'ilt- 
agtige Character som hos C. malleolata. Fingrene er her 
kjendelig hengere end Palmen, og den ubevmgelige Finger 
smalere end hos de 2 ovrigo Arter og mere tydeligt be- 
grsendset fra Palmen, idet Forkanten paa Grsendsen mellem 
begge danner en tydelig, omend svag, Indbugtning. I Tn- 
the inner edge, of which one is affixed near the middle; 
terminal claw very elongate, conically acuminated at the 
extremity. Colour whitish-yellow. Length of body 10”™, 
extent 80”™. 
Remarks. The present species is chiefly charac- 
terised, compared with the 2 preceding ones, by its ex- 
ceedingly' short neck, and hence its specific designation. 
It is, moreover, easily recognised by the less prominently 
expanded frontal part, as also by the structure of the chelifori 
and ambulatory legs. 
Description. The length of the body in full-grown 
specimens is 10””", the extent 80”™ ; this species attains 
therefore, a very considerable size. 
The body (se PI. IY, fig. 3) is, on the whole, com- 
paratively robust, and the animal resembles in that respect, 
at first sight, rather the typical form than the preceding 
species, notwithstanding that the ambulatory legs are a 
good deal more elongate than in the former. The trunk 
itself (see fig. 3 a) exhibits a very thickset and compact form, 
and the lateral processes are, consequently, marked off by 
only very narrow, fissure-like interspaces. The cephalic seg- 
ment is relatively much smaller than in the 2 preceding 
species, not attaining, by far, half the length of the trunk, 
nor is the frontal part so prominently expanded. The neck 
in the present form is distinguished from that of the pre- 
ceding species, by being very short, considerably shorter even 
than in the typical form, and between the frontal part and 
the foremost lateral processes there is, therefore, but a nar- 
row interspace, which at the sides is wholly filled iqi by 
the articulatory knots of the false legs. The caudal segment 
exhibits nearly the same appearance as in C. malleolata. 
The oculiforous tubercle is very low and evenly rounded, 
and characterised by the small size of the lenses (see fig. 3 b); 
the latter occur still farther apart than in C. malleolata, 
and are distinctly arranged 2 and 2 on each side, each with 
a comparatively small and sharply defined pigmentary cup. 
The proboscis (see fig. 3 a) would seem to be rela- 
tively somewhat larger than in the 2 preceding species, at- 
taining well-nigh the length of the cephalic segment; its 
structure is for the rest precisely as in those forms. 
The chelifori (see fig. 3 a) are indeed, ;fe compared 
with those in other Pycnogonids, rather powerfully devel- 
oped, though not, by far. to such an extent as in the typical 
species, and even in the preceding species these limbs 
would appear to be in some respects more robust. The 
scape is quite smooth, cylindrical, but with the outer edge 
a little incurvated at the base. The hand is by no means 
so tumid as in the 2 preceding species, and therefore not 
so prominently globular, but is somewhat irregularly com- 
pressed in form. It is everywhere densely beset with ex- 
ceedingly short hairs, which, as they approach the immobile 
finger become somewhat longer, without however assuming 
the felt-like character observed in C. malleolata. The 
fingers are in this animal appreciably longer than the palm, 
and the immobile finger is slenderer than in the 2 other 
species and more distintly marked off from the palm, as 
the anterior edge, on the boundary between both, forms
