sutures, while the fine, microscopic, spiral strife, only to be 

 seen with the aid of a strong lens, are not traceable in C. 

 straminea, and the characteristic arch of the outer lip is not 

 so pronounced in this as in the last-named species" (Burnup) . 



Species of India, Farther India and China. 



C. plicifera, no. 29, has an entering parietal lamella. Its 

 generic position is doubtful. 



Hapalus travankoricus Theobald, Journ. As. Soc. Beng., 

 1876, xlv, pt. 2, p. 186, pi. 14, f. 5, is according to Blanford 

 the young of Cataulus calcadensis or some closely related 

 species. See J. A. S. B., xlix, pt. 2, p. 215 (1880). 



29. C. PLICIFERA (Blanford). PI. 9, fig. 45. 



"Shell obtectly perforated, ovately conical, rather thin, 

 horny, finely striated. Spire conical, apex obtuse, suture 

 marginate, scarcely impressed. Whorls 5, planulately convex 

 above, the last longer than the spire, somewhat tumid, rounded 

 at the base. Aperture vertical, truncately oval, subpiriform; 

 peristome simple; right margin curved forwards; columella 

 callous, subvertical, slightly curved, rather broadly reflexed; 

 margins united by a callus bearing a small re-entering lamella 

 about the centre. Length 9, diam. 5.5 mm." (Blanford).

"A more tumid shell than B. putus Bens., and easily dis- 

 tinguished from all other Indian and Burmese forms of the 

 genus by the re-entering parietal plait." 



The systematic position of this species is uncertain. I have 

 not seen specimens.

Shell perforate, ovate-acute, thin, striatulate, whitish under 

 a thin corneous epidermis. Spire conic, the apex rather ob- 

 tuse, suture well impressed. Whorls 6, convex, the last 

 slightly exceeding half the shell's length. Aperture vertical,
