F u r c a: — Behind thé claws there is an un paired, long-haired bristle whieh is about
as long as the seventh or eiglith claw.
The rod-shap e d organ is as described and reproduced by Gr. W. Müller ; see the
accompanying fig. 3.
The u p p er 1 i p and p a rag nates are of the same types as in my figs. 37 and 38
of C. symmetrica.
Bemärks: — G. W. MÜLLER in his work of 1908 (p. 74) points out that C. magna,
CH. Juday, 1906, p. 19 is not a synonym of C. magna C. CLAUS; Müller writes with regard
to the description given by JUDAY: „eher paßt sie zu Conchoecia lophura G. W. MÜLLER“.
The same writer, in his synoptic work of 1912, puts this species of Ch. Juday’S as a synonym of
C. lophura, but adds a (piery. It can be considered beyond doubt that C. mugna Ch. Juday
is not a synonym of C. mugna C. CLAUS. Certainly its identity with C. lophura seems to me
far from impossible, but it is so uncertain that it did not seem to me proper to include the name
in question in the list of synonyms given above.
To judge from Fowler’s description it seems very probable that G. H. FOWLER’s
„Lophura-stage“ of C. hyalophyllum is identical with C. lophura.; see p. 565 above.
Habitat: — Antarctic Ocean: —
S. A. E., Pl. station 64 b, lat. 48n27’ S., long. 42° 36’ W. ; depth 2500—0 m.; 23. VI.
1902: 1 mature male; on slides in the collections of R. M. S.
Distribution: — Atlantic Ocean from about lat. 46° N. (G. H. Fowler) to lat. 35° S.
(G. IV. Müller), Indian Ocean (G. W. Müller).
The station of the Swedish „A n t a r c t i c“ Expedition is consequently situated
some-what south of the distributional area stated by previous authors.

Supplementary description: — F e m a 1 e : —
Shell: — The specimens investigated by me were from 2,4 to 2,7 mm. long. The
sculpture varied to some extent, sometimes resembling the type reproduced by G. W. MÜLLER
for C. lophura and exceedingly difficult to observe. The selvage, the glands along the posterior
margin of the shell and the hinge were of the types described above for (’. lophura. In othex
respects it agreed with G. W. Müller’,s statement.
