Hovedsegmentet af Legemets halve Laengde, naar Snabelen

foregaaende Art. Saxlemmerne forboldsvis mindre robuste, 
Skaftet smalere, Haanden kugleformigt opsvulmet og besat 
med korte Haar. Fingrene kortere end Palmen, mindre 
stserkt chitiniserede og mindre krummede i Spidsen. den

slaegtet med foregaaende Art, er denne dog let kjendelig ved 
den betydelig spinklere Legemsform, den lange og smale 
Hals og de starlit forbengede og tynde Gangfodder. Og- 
saa i Saxlemmernes Bygning er der vel udpragede Diffe- 
rentser, ligesom ogsaa Gieknuden viser et foiskjelligt koi- 
hold af Synselementerne. 
Beskrivelse. Lamgden af Legemet bos fuldvoxne In-

Legemsformen er (se PI. IV, Fig. 2) betydelig slan- 
kere end hos den typiske Art, baade hvad selve Kroppen 
og Lemmerne angaar, og Legemets feidefortsatser, som hos 
foregaaende Art var tset sammentramgte, er som Felge

(PI. IV, fig. 2, a — g). 
Cordylochele longicollis, G. 0. Sars, Pycnogonidea borealia 
& arctica, No. 12. 
Specific Character. Body much more slender than 
in the preceding species, with the lateral processes wide apart. 
Cephalic segment half the length of the body, excepting the 
proboscis, with the neck remarkably elongate and slender ; 
frontal part well defined but relatively much smaller than in C. 
inalleolata, scarcely halt as long as the neck and not attaining 
twice the length of the body. Oculiferous tubercle somewhat 
more protuberant than in the preceding species, with ex- 
ceedingly large, well-nigh contiguous lenses. Proboscis as in 
the preceding species. Chelifori relatively less robust, scape 
slenderer, hand globularly tumid and beset with short hairs, 
fingers shorter than palm, less strongly chi t inis ed and not 
so curved at the point. The lamelliform process smooth, 
not dentate. False legs in male very elongate and slender; 
5th joint shorter than both the preceding ones taken together; 
1st joint of terminal part considerably elongated; lateral 
spines much as in the preceding species; terminal claw 
slender and elongate. Ambulatory legs sparingly furnished 
with hair, comparatively slender, 4 times the length of body ; 
2nd coxal joint much longer than both the others taken 
together; femoral joint twice as long as the coxal region , 1st 
tibial joint about the length of femoral joint, 2nd half as 
long again; tarsal joint triangular, hardly broader than long, 
with a single spine at the end of the inner edge; pro- 
podal joint slender and elongate, well-nigh straight, with 5-6 
' strong spines at the base of the inner edge ; terminal claw 
almost the length of propodal joint, compressed, falciform. 
Colour whitish. Length of body S’™, extent 1 7' 1 ’ . 
Remarks. Though doubtless very nearly related to 
the preceding species, this form may he easily i ecognised 
by its much slimmer body, the long and naiiov neck 
and exceedingly elongate and slender ambulatory legs. In 
the structure, too, of the chelifori well-marked differences 
occur, and the oculiferous tubercle also exhibits a deviating 
relation with respect to the visual elements. 
Description. The length of the body in full-grown 
specimens is about 8 ran ’, the extent 77 mm , and this species, 
therefore, does not attain the considerable size of the pre- 
ceding one. 
The body (see PI. IV, fig. 2) is much more slim than 
in the typical species, both as regards the trunk itself and 
the limbs ; and the lateral processes of the body, which in 
the preceding form were crowded together, are, in the present 
I on0< from this cause, separated by rather wide interspaces. 
The cephalic segment (see fig. 2 a, 2 b) occupies quite half
