Genus BARLEEIA Clark.
BAKLEEIA SMITHI, new spedies.
Plate 10, fig. 5.
Shell broadly ovate, light chestnut brown, with the parietal wall and
the inner edge of the columella dark chestnut. Nuclear whorls not
differentiated from the rest of the shell. Postnuclear whorls rounded,
marked by decidedly retractive lines of growth and exceedingly fine,
closely spaced, microscopic spiral striations. Sutures strongly constricted.
Periphery of the last whorl inflated, strongly rounded.
Base short, strongly rounded, umbilicated, marked like the spire.
Aperture subcircular; outer lip thm; columella moderately thick,
slightly reflected; parietal wall covered by a thick callus, which
renders the peritreme complete.
The type and three other specimens, Cat. No. 227741, U.S.N.M.,
come from Port Alfred (Coll. No. 836). The type has four whorls and
measures: Length, 1.5 mm.; diameter, 0.9 mm.
Genus FENELLA A. Adams.
FENELXA ALMO, new species.
Plate 31, fig. 4.
Shell elongate-conic, milk white, rather thick. Nuclear whorls
smooth, well rounded. Postnuclear whorls well rounded, marked by
a strong, median, spiral keel and another a little less strong at the
periphery. These keels become more strongly developed on the last
turn than on the preceding turns. In addition to these, there are
numerous, very fine, spiral threads between the keels and also upon
them, which are crossed by equally fine axial threads, lending the
entire surface a finely reticulated appearance. There are also a few
irregularly disposed, low, ill-defined axial riblets, which are best shown
on the last half of the last whorl. Base well rounded, ornamented like
the spire. Aperture thin within, provided with a complete peristome
at the edge, which is greatly thickened and built out, and slightly
reflected all around.
The type, Cat. No. 249708, U.S.N.M., comes from Port Alfred (Coll.
No. 980). It measures: Length, 7.1 mm.; diameter, 2.6 mm.
Family JEFFREYSIIDAE.

Cat. No. 186822, U.S.N.M. Three specimens from Port Alfred
