2. Pycnogonum crassirostre, G. 0. Sars. 
(PI. I, fig. 2, a -hi. 
Pycnogonum crassirostre, (i. 0. Sars, Pycnogonidea borealia & 
arctiea, No. 2. 
Specific Character. — Body more elongate than in 
preceding species, almost cylindrical, anteriorly stouter, 
with lateral processes comparatively short and separated 
by wider intervals. Along the dorsal surface of the body 
extend a series ot obtuse protuberances. Caudal segment 
oval throughout, with the point evenly rounded off. Oc- 
uliferous tubercle obtusely rounded, with comparatively 
large, closely set con lose. Proboscis pointing oblique- 
ly downwards, relatively short and thick, but very little 
more than one-third the length of the body, conico-cylindric, 
with extremity truncate, not produced. The false legs in tin* 
male very small and teeble, having the 2 first joints larger 
than the rest, terminal claw slender and but slightly 
curved. Ambulatory legs shorter than body, of a structure 
similar to that in the preceding species, but with the 
tarsus more slender and more regularly quadrangular. 
Colour brownish or rusty. Length of female reaching 
I0 mm , that of male 6*/ s wm . 
■Remarks. — This new species may be easily distin- 
guished from P. . httorale, not only by its inferior size, its 
more slender, well-nigh cylindrical body, the short and 
widely distant lateral processes, the hum of the caudal 
segment, but also, and in particular, by its considerably 
shorter and thicker proboscis, from which latter character 
indeed the specific designation is derived. In the structure 
too ol the false legs and of the ambulatory legs can be 
shown divers minor differences, that place the genuineness 
of the species beyond all doubt. 
Description. — The length of the body in the fully 
developed female reaches only 10 mm , hence is a good deal 
less than in the preceding species. The male is much 
smaller, not more than long. 
The body is in both sexes (see PI. 1, fig. 2, 2 a) 
lather robust, though perceptibly slenderer than in the pre- 
ceding species, almost cylindrical, and tapers somewhat an- 
tero-posteriorly. The segments are marked off very sharp- 
ly fr° m each other, and somewhat districted in the fore- 
most part. The lateral processes issuing from them are 
comparatively very small, and, unlike what is the case in 
the typical species, separated one from the other by rather 
wide intervals. Along the dorsal surface of the body oc-
