6 CRUSTACEA COPEPODA. II. 
Among the 3 specimens one is an ovigerous female placed on the lower side of the disk of the Asterid, 
another ovigerous female is found between two arms, and the third, a female without ovisacs, is fallen off. 
The last-named specimen has been investigated; it agrees on the whole well with Sars’ figures, excepting 
that the postero-lateral angles of the head and of the two anterior free thoracic segments are a little more 
produced. 
Distribution. — Taken by Boeck and Sars at the south coast and off the west coast of Norway. 
According to the somewhat intricate synonymy elucidated by Giesbrecht and Sars, the species has been 
noted by Brady from Ireland and by Scott and Giesbrecht from Firth of Forth, Firth of Clyde and Loch Fyne.

Occurrence. — Not taken by the “Ingolf”’, but by Mag. sc. W. Lundbeck at the following place. 
North-West Iceland: Talknafjord, 14 feet, ooze with much vegetation, July 4, 1899. 5 females. 
Distribution. — Taken at Bukken, SW. coast of Norway, and at Rau6, west coast of Norway 
(G. O. Sars). Furthermore noted from Ireland (Brady), from the Island of Man (Thompson) and from Firth 
of Forth on Chalina oculata (Th. Scott). Finally near Hope Island (south-east of Spitzbergen), 27 fath. 
(Th. Scott). Giesbrecht’s statement on its occurrence at Naples is considered doubtful by Sars. 
4. Ascomyzon intermedium n. sp. 
(Pl. I, figs. 2 a—2 g.) 
Female. — Moderately broad; head about as broad as the length of first thoracic segment and head 
together. Posterior corners of the thoracic segments angular, scarcely rounded, not produced; third segment 
seen from above very short. — Genital segment (fig. 2 b) more narrow than in any described species, one- 
fourth as long again as broad, and the part in advance of the genital aperture is even slightly narrower than 
the front end of the posterior part; second abdominal segment considerably shorter than the third which 
is almost as long as broad; caudal rami with their outer margin decidedly longer than their breadth and 
slightly shorter than second abdominal segment. 
Antennulee with 20 joints, and as to the relative length of these joints so similar to those of the follow- 
ing species, A. tenerum, that the drawing (fig. 3 d) of this species is deemed almost sufficient; eleventh to 
seventeenth joint from considerably to very much longer than broad; eleventh joint rather long; from eleventh 
to fourteenth the joints decrease a little in length; fifteenth as long as eleventh; sixteenth (fig. 2 c) distinctly 
longer than fifteenth and somewhat shorter than seventeenth, which is slightly longer than the three distal 
joints together and four times as long as thick. — Antenne (fig. 2 d) somewhat slender; terminal spine as 
long as the two distal joints together. — The sipho shaped nearly as in A. datum (comp. the figure on pl. LVI 
in Sars’ Account) and reaches beyond the base of first legs. — Maxillule (fig. 2 e) with the inner branch 
moderately robust and with 3 of its terminal sete a little to considerably longer than the branch; outer branch 
slender and short, only about one-fourth as long as the inner one, but at least one of its terminal setee reaches
