Description: — Female: —
S li e 11: — Length, 3,3—3,65 mm. \V. Baird spécifiés a length of 3,81 mm. ( 1,5 line);
G. S. Brady and A. M. Norman give a length of 4 mm. for this species. These authors do not
give*any information about the range of variation of the length. Length : height, about 1,4 : 1;
length: breadth, about 1,75 : 1. Seen from the side the form varies somewhat, thought onlv
slightly (figs. 1 and 2).- It is oval with the greatest height at about or just behind the middle
and the posterior part on ly very slightly larger than the anterior one. The dorsal and ventral
margins are uniformly and rather boldly arclied, the arcuation of the former somewhat stronger
tlian that of the latter; both without corners joining the anterior and posterior margins. The
rostrum is well and uniformly arched anteriorly, without any anterior corner; its ventral corner
rather pointed. The rostral incisur is deep and narrow. The posterior part of the shell is
broadly rounded with only a fahrt indication of a broadly rounded posterior corner somewhat
below half the height of the shell or else it is rather strongly trimcated (fig. 2). S e e n f r o m
below (fig. 3) it is oviform with its greatest breadth somewhat behind the middle; the anterior
and posterior ends are well rounded, the posterior somewhat broader than the anterior one.
The surface of the shell is almost quite smooth with only an exceedingly faint indication of
small cavities just within the anterior margin of the shell; in most cases this sculpture is
scar-cely distinguishable. There are no bristles on the surface. The pores of the surface are very
difficult to distinguish. See.n from within (fig. 4): Medial bristles: On the rostrum there is an
irregulär row of rather short and most frequently bifurcated bristles directed slantingly forwards
and upwards [about the same type as is reproduced for C. (Doloria) levis, fig. 2];
the place on which the ventral bristles of this row are fixed is not developed into a verruciform
protubérance. In front of and behind this row there are a few scattered bristles. Along the
ventral edge of the rostrum there is a great number of scattered bristles; most of these latter
are of about the same type as the bristles in the row. Sometimes all the bristles on the
rostrum are scattered without any arrangement in a distinct row; they also vary considerably
in number. The two bristles near the inner edge of the rostral incisur are of about the
same size as the bristles on the rostrum; they are bare or furnished with short, fine hairs
