The new localities mentioned by me above are conséquent ly within the region of
distribution previously known. 6. W. MÜLLER’s statement (1908, p. 67) that this species never
occurred in samples of the „D e utse he Siid-Polar-Expedition“ from stations
south of lat. 43° S. is noteworthy („auch der Fang unter 43° steht vereinzelt ela“). This writer
then adds: „danach scheint es sich bei dem Fang der „V a 1 d i v i a“ unter 55° S. Br., der auch
ganz vereinzelt dasteht, um verschlagene Individuen zu handeln“. The localities south of
lat. 43° S. given by me above seems to show with all certainty that this assumption cannot be
corrrect; cf. also the size of the specimens found by me in Antarctic waters with that of the
Atlantic specimens.
Daphnoides group G. W. Müller
(Conchoecilla C. Claus.)
This group, comprising, in addition to the species dealt with below, only two other species,
is certainly quite a natural one.

Description: — See G. W. Müller, 1906 a, p. 124.
Supplementary description: — Male: —
Shell: — Length: According to G. W. Müller, 1,4—1,55 mm. The specimen
investi-gated by me was 1,5 mm. long. Seen from the side it is of the type described and
reproduced by G. W. Müller. The posterior dorsal corner differs only very slightly in the
right and left valves; in the right one it is furnished with an exceedingly small point; just in
front of this corner the right valve is aimed with one or two more or less powerful spines; see
the accompanying fig. 1. The rostrum is symmetrical and of about the same type as is shown
in pl. XXXI, fig. 19, G. W. MÜLLER, 1906 a. The shoulder vault is moderately developed and
well rounded. The surface of the shell is bare. The sculpture and glands have been described
by G. W. Müller. Seen from inside: The selvage is smooth-edged except along the
posterior part of the ventral margin of the shell, where it is exceedingly finely serrulated. There
is no hinge-socket or hinge-tooth at the posterior dorsal corner.
First antenna: — This is of the type described and reproduced by G. W. MÜLLER.
E-bristle: Proximally on the anterior side this is bare or almost bare (a few exceedingly
short and fine hairs may perhaps be discovered with very great magnification) ; it is
