subglobose. Aperture auriform, a little exceeding half the 

 total length, furnished with a single minute parietal tooth. 

 Outer lip thin, arcuate. Columella straight, thick, at the base 

 abruptly truncate. Length 2, diam. 1.5 mm. (Smith).

"Under the microscope the surface has a minutely frosted 

 appearance, produced by excessively fine spiral striation" 

 (Smith). 



The apertural lamellae are very much reduced in this spe- 

 cies. The adult form, shown in Mr. Smith's figure, which is 

 copied on pi. 30, fig. 7, has only an extremely narrow, straight 

 columella, truncate at the base, but half -grown shells of 2 1/2 

 whorls (pi. 30, fig. 6, length 1.5 mm.) have a broader colu- 

 mellar plate with convex edge. The shell, at all stages of 

 growth, is decidedly fragile. Though smaller, it has some 

 resemblance to E. anceyana. 



10. E. SUNDANUM (Moellendorff). 



Shell imperforate, ovate-conic, thin, subpellucid, very 

 lightly striatulate, opaque, buff-corneous. Spire moderately 

 elevated for the genus, convexly conoid. Whorls 4, a little 

 convex, rather rapidly increasing, the last quite convex. 

 Aperture not very oblique, oval, somewhat excised. Peristome 

 unexpanded, acute. Columella lamellarly dilated above, trun- 

 cate in the middle. Parietal lamella moderate, produced deep 

 within. Length 3, diam. 2 mm. (Mlldff.).

11. E. CERNICUM (Benson). PI. 31, figs. 1, 2, 3, 4. 



Shell globosely conic, thin, striatulate, obsoletely decus- 

 sated by extremely fine spiral striae, pale corneous, pellucid, 

 glossy. Spire conic, the apex obtuse, ruddy. Whorls 4, con- 

 vex. Aperture elliptical-ovate, longer than the spire, con- 

 tracted by two folds : one lamellif orm, entering, hyaline pari-
