Page 122. Add the following species:
Macrostylis longiremis (Meinert).
(Suppl. PI. H, fig. 1).
Vana longiremis, Meinert, Crustacea malacostraca (from the cruise of the steamer ,,Hauch").
p. 195, PL H, figs. 6373.
Specific Characters.- Very like M. spinifera, but, on a closer examination,
easily distinguishable by the somewhat different shape of the caudal segment, which
is not nearly so much produced at the end, between the insertion of the uropoda.
The 3rd pair of legs with the ischial spine less curved, and distinctly bidentate at
the tip. The 3 posterior pairs of legs comparatively less slender than in the
type species. Uropoda not attaining the length of the caudal segment, and having
the distal joint nearly half as long as the proximal one. Length of adult female
2Ya mm.
Remarks. It is Dr. Hansen who has called my
attention to the fact
that the form described by Prof. Meinert as Vana longiremis does not exactly
agree with Macrostylis spinifera, to which I have formerly adduced it as a syno-
nym. Through the kindness of that distinguished zoologist,
I have received several
specimens of the Danish form, and a closer examination of these has indeed
convinced me that it ought to be regarded as a distinct, though very closely
allied species. The differences between the 2 species may be easily seen on a
comparison of the figures given on the accompanying plate,
with those on PI. 51.
Occurrence. This species has certainly not yet been found off the Nor-
wegian coast; but as it occurred rather frequently in one Station (460) lying in
the Skagerak at rather a long distance north of Skagen, it may with almost equal
right be referred to the Norwegian fauna as to the Danish. In all probability
it will, on a closer investigation, be found to exist off the coasts of both countries.

Desmosoma angustum, Hansen, MS.
(Suppl. PL H, fig. 2, PL IV, fig. 2).
Specific Characters. Body of female very slender and narrow, being more
than 6 times as long as it is broad, and somewhat moniliform, with the segments
sharply marked of from each other. Cephalon of moderate size, distinctly notched
