Description: — F e m a 1 e: —
Shell: — Length 2,95—3,1 mm. ; length : height about 1,75 : 1; length : breadth about
2:1. Seen from the side (fig. 1) it is rather elongated, with its greatest height somewhatbehind
the middle and the posterior part somewhat, though only slightly, larger than the anterior part.
The dorsal and ventral margins are moderately and almost uniformly curved, with almost
the same shape, but the dorsal margin is somewhat more flattened anteriorly than the ventral
( me ; they pass evenly into the anterior and posterior margins without any corners. The anterior and
posterior margins are uniformly and boldly, almost semi-circularly, rounded. The rostral incisur
is situated rather considerably ventrally of half the height of the shell. Se en from beneath
(hg. 2) the shell is rather narrow and egg-shaped, with its greatest breadth somewhat behind
the middle; the posterior end is somewhat more broadly rounded than the anterior one, the side
contours are evenly curved. Seen from inside: Medial bristles: On the rostrum there is a fairly
distinct, moderately close, row of moderately long, stiff bristles, running somewhat within and
about parallel with the anterior margin of the shell. Within this row there are usually only
rather few scattered bristles on the rostrum; some of these bristles are moderately long, most of
them, however, are verv short - they vary somewhat in number. In the incisur there are rather
mimerons moderately long, stiff bristles, all quite without any definite arrangement. On the part
