E. B. Wilson — Pycnogonida of New England. 
Pseudopallene discoidea Wilson. 
Pallene discoidea Kroyer, Nat. Tidss., lste Bind, 2det Ha?fte, p. 120, 1844; Yoy. 
en Scand., Laponie, etc., PI. 37, fig. 3a — g\ Isis, Jahrg. 1846, Heft vi, p. 443. 
Plate III, figures 3 a to 3c. 
Body oval, somewhat narrower than that of P. hispida , lateral pro- 
cesses in close contact. Abdomen pointed, slightly bifid at the tip. 
Rostrum obtuse, slightly hairy, outline of sides convex. 
Antennae stout, but not so much so as in P. hispida ; basal joint 
not enlarged near the base. Chelae with the claws acute and finely 
serrated along the opposable margins, second joint with no tubercles 
on the inferior margin. 
Accessory legs stout ; all of the joints are short and broad, the 
fourth and fifth longest; terminal joint acute; the 7th, 8th, 9th and 
10th joints bear each a simple spine on the upper side. 
Legs nearly as in P. hispida, but longer and more slender, particu- 
larly in their basal portion, where the joints do not overlap. 
The legs and body are armed with conical hairy tubercles arranged 
nearly as in the preceding species. Color light yellowish brown. 
Length 3 millimeters. 
This species, like the preceding, is represented by a single specimen, 
apparently not yet adult ; it was taken with Caprella on the tangles 
in 20 fathoms, rocky bottom, Eastport harbor, by the U. S. Fish Com- 
mission, Aug. 9, IS 72. 
This species is very similar to the last, and a larger number of 
specimens may show them to be identical. The two specimens 
described present, however, well marked differences, particularly in 
the shape and armature of the antennae, the shape of the rostrum, 
abdomen, etc. Though not agreeing perfectly with Ivroyer’s figures 
of P. discoidea there can be little doubt of the identity of this species 
with it. 
Phoxichilidium Milne Edwards. 
Body slender ; neck short. Rostrum cylindrical, rounded. Anten- 
nae three-jointed, chelate. Palpi wanting. Accessory legs five-jointed, 
absent in the male. Legs slender ; dactylus with auxiliary claws. 
Phoxichilidium maxillare Stimpson.

Body rather stout. Oculiferous segment twice as broad as long. 
Oculiferous tubercle prominent, acute. Eyes ovate, nearly white in
