Bemmrkninger. At baade den af Hodge som Pallene 
pygmcea opforte Form og Dohrn’s Phoxichilidium longicolle 
borer berhen, anser jeg for utvivlsomt. Ligeledes maa jeg 
vsere enig med Hansen, naar ban opforer den af Semper 
under Bensevnelsen Phoxichilidium, nmtilatum omtalte Form 
fra Helgoland som Synonym. Arten har ved den smalt 
udtrukne Hals og hoic 0ieknu.de et saa c.haracteristiskt 
Udseende, at den neppe er til at tage feil af. 
Beskrivelae. Hunnens Lsengde er neppe mere end 
2“"*, med en Spandvidde af 10'”'”. Hannerne er som ssed- 
vanlig lidt mindre. 
Legemet er (se PI. II, Fig. 2, 2 a, 2 b) noget under- 
ssetsigt og i For hold til Lsengden temmelig bredt, lidt ned- 
trykt og afsmalnende bagtil, med vel markerede Suturer

men ikke meget vidt adskilte. De har hver ved Enden

Anoplodadylus petiolatus, G. 0. Sars, Pycnogonidea borealia 
et arctica, No. 5. 
Specific Character. — Body rather broad, somewhat 
flattened, with the lateral processes less widely separated, and 
each having above, at the extremity, a 'small conical pro- 
jection. Cephalic segment as long as the 3 following 
segments collectively, produced anteriorly to a very nar- 
row neck, extending over the base of the proboscis. 
Caudal segment horizontal, greatly prolonged. Oculiferous 
tubercle remarkably protuberant, cylindric, furnished on each 
side of the point with an angular projection; the 4 cornese 
nearer the point than the base, position oblique, the 2 posterior 
ones higher up than the 2 anterior ones. Proboscis compara- 
tively short, scarcely more than one-third as long as the body, 
plain, cylindric. Chelifori measuring the length of proboscis, 
scape narrow cylindric, chela half as long, fingers about the 
length ol palm, immobile finger well-nigh straight, mobile 
finger uniformly curved and longest. False legs in the male 
about the length of the body (excl. proboscis); 3rd joint very 
elongate and slender, the 3 outer joints diminishing rapidly i;i 
size, last one exceedingly small, oval. Ambulatory legs scar- 
cely more than twice as long as the body, comparatively slen- 
der and beset witli scattered bristles, femoral joint largest and 
about the length of coxal region, the 2 tibia! joints equally 
long, tarsal joint very small, triangular, propodal joint slender, 
sharply curved, arid at the base forming inwards a narrow, 
rounded lamellar expansion armed with 2 strong spines ; inner 
margin oi the joint armed with a row of small, anteriorly 
curved spines, to which succeeds a thin, undivided lamella; 
terminal claw well-nigh as long as propodal joint, falciform. 
Colour whitish. Length of body 2”™; extent 10”™. 
Remarks. — The form described by Hodge as 
Pallene pygmcea, and Dohrn’s Phoxichilidium longicolle be- 
long, I think, unquestionably, to this species. Moreover, 
I quite agree with Hansen in regarding the form from 
Helgoland, mentioned by Semper under the name of Phox- 
ichilidium nmtilatum, as a synonym. The species acquires 
by reason of the slenderly produced neck and protuberant 
oculiferous tubercle, so characteristic an appearance, as to 
hardly admit of confounding it with any other. 
Description. — The length of the female is scarcely 
more than 2 mm , with an extent of 10”””. The males are, as 
usual, a trifle smaller. 
The body (see PI. II, fig. 2, 2 a, 2 b) is somewhat 
short and stout, and, relatively to its length, rather broad, 
slightly flattened, and tapers posteriorly, with well marked 
sutuies between the segments. The lateral processes are 
comparatively long, but not much separated. They each 
have at the extremity above, a small conic projection, and
