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 con- 

 stricted. 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. 



Genus JEFFREYSIA Alder.

 from the same locality (Coll. No. 993).
