and the limbs (pi. LIX, figs. 19 and 20) that it must be said that synonymization is impossible. We
have perhaps here too, however, mistakes in observation and drawing on the part of the authors
— it is certain that the limbs are exceedingly incorrectlv drawn — nor does it seem impossible,
as I point out in the remark under A. abyssicola, that in pl. LII there has been confusion between
figures 17 and 19. — This species described by these writers cannot be synonymized with the
above-mentioned species of G. O. Saks’s either. Nor does G. W. MÜLLER, 1912, p. 46, include
it as a synonym of A. elliptica,.*
Habitat: — I r e 1 a n d: Strangford Lough (type 1 o c a 1 i t y) ; no information about
the depth and the nature of the bottom was to be found on the label: 2 mature females and
2 juvenes; coll. G. S. BRADY.
Type specimen on slides in the collections of the R. M. S.
Asterope Grimaldi n. sp.
Description: — Female: —
Shell: — Length, 1.53—1.7 mm.; length : height about 2,2:1; length : breadth
about 2,4 : 1. Seen from the side (fig. 1) it is very much elongated with the greatest
height at about the middle and with the anterior and posterior parts of about the same height.
The dorsal and ventral margins are almost parallel and are very weakly, uniformly and almost
symmetrically curved, the ventral margin is, however, as a rule, somewhat flattened anteiiorly.
These margins pass evenly into the anterior and posterior margins without forming any corners.
The anterior and posterior margins are boldly rounded, almost into semi-circles, and have about
the same shape; the latter is, however, somewhat flattened dorsally in most cases. Seen
from b e n e a t h (fig. 2) it is narrow and oviform, with its greatest breadth at about
two-thirds of the distance along the shell; the posterior end is rounded somewhat more broadly
than the anterior end and the side contours are evenly curved. Seen from inside:
Medial bristles : On the rostrum there is a sparse row of stiff and moderately long bristles, running
parallel to and somewhat inside the anterior margin of the shell. Within these there are a
moderate number or rather few scattered bristles, most of them short, some about as long as
the bristles in the anterior row. In the incisui there are a few stiff and moderately long bristles,
a number of which are scattered, and some are often arranged in a sparse row running about
parallel to and somewhat inside the ventral margin of the rostrum. On the part just behind
the incisur there are also a moderate number or rather few bristles. Some of these are often
placed in a sparse row running about parallel to and somewhat inside the ventral margin; these
bristles are moderately long. The others that are situated farther in are scattered and more
or less short. About parallel to and somewhat within the ventral margin of the shell there is
a row of rather short bristles. which is partly very sparse and sometimes not very distinct.
* ..A. elliptica“-is also found by E. Graefff., 1900, p. 34. No description is given and it is consequently quite
impossible to say anything about the svnonyiny of this form.
