102 COCHLITOMA. 



31. C. NATALENSIS (Pfeift'er). 



Shell ovate-conic, rather solid, whitish, covered with a 

 straw-colored epidermis ; spire regularly conic, obtuse ; whorls 

 7y 2 , a little convex, the upper very minutely, the following 

 more distinctly undulate-granulate; last whorl about as long 

 as the spire, striate, decussated near the suture with a few 

 spiral stride. Columella arcuate, somewhat twisted, inflated, 

 narrowly truncate. Aperture slightly oblique, acuminate- 

 oval; peristome simple, thin. Length 62, diam. 28, aperture 

 31x17 mm. (Pfr.).

V. Species incerta? sedis. 



32. C. AURORA (Pfeiffer). 



Shell oblong-ovate, solid, rather smooth, fulvous, variegated 

 with sparse deep chestnut streaks. Spire conic, obtuse ; suture 

 margined. Whorls 6, a little convex, the last about equal 

 to the spire. Columella very arcuate, purple, the base broadly 

 truncate. Aperture a little oblique, sinuate-oval, lilac-rose 

 colored within, glossy; peristome simple, brown-margined, 

 the margins joined by a roseate entering callous. Length 

 59, diam. 28, aperture 33x16 mm. (Pfr.).

This will probably prove to be no South African shell, but 

 from West Africa, where many species have similarly colored 

 interiors. 



33. C. LINTER^ (Sowerby). PL 29, fig. 43. 



Shell ovate, thin, glossy, white, covered with a fulvous 

 cuticle, painted in a single series above the middle with brown 

 spots. Spire conic, the apex obtuse ; suture impressed, sub- 

 crenulate. Whorls 7, a little convex, granose-plicate ; last 

 whorl inflated, obsoletely grano-plicate above, then smooth. 

 Aperture vertical, subovate, white in the throat, blue mar-
