244 COCHLOSTYLA. 



A small, delicate species, having a prominent white keel and a 

 thin pink lip. Specimens were collected by Mr. Woodford, and are 

 now in the British Museum. 



C. AGGIEI Heimburg. PI. 57, figs. 7, 8, 9. 



Shell almost covered rimate-perforate, depressed-globose, thin, 

 pellucid, obliquely closely plicatulate, decussated by fine spiral lines. 

 Almost colorless, begirt with numerous milk white bands, sometimes 

 splitting. Apex obtuse ; whorls 4, rapidly increasing, convex, the 

 last large, not descending in front, inflated below, carinated at the 

 periphery. Aperture large, lunate-ovate, three-fourths the height 

 of the shell, oblique ; peristome broadly reflexed, columellar margin 

 much dilated, covering and almost closing the narrow umbilicus. 



Greater diam. 27, lesser 19 mill. ; aperture oblique alt., including 

 peristome 17, width 18 mill. (Heimb.')

This form should possibly be considered a variety of C. allasteri 

 Cox, from which it differs in the narrower umbilicus and apparently 

 in the somewhat stronger sculpture. 



C. TENIMBERICA Mollendorff. For figs, see Vol. IX. 



Shell imperforate, subdepressed-globose, thin, diaphanous, shining, 

 minutely, closely and distinctly plicate-striate, decussated with spiral 

 impressed lines, more distinct below the carina; malleated, buff- 

 whitish ; spire subhemispherical, the apex nearly flat. Whorls 34- 

 4, rapidly increasing, separated by a subappressed, margined suture, 

 slightly convex, the last whorl obtusely carinated at the periphery, 

 somewhat excavated below the carina, much inflated beneath, sub- 

 compressed and a little gibbous around the columellar. Aperture 

 very oblique, broad ax-shaped, the peristome very narrowly expanded 

 above, thin, acute, a little expanded below and somewhat labiate ; 

 columella compressed, subexcavated, straightened, forming an 

 indistinct angle where it joins the basal lip. 



Alt. 16, diam. 23 mill. ; aperture width 15, length 14, alt. 12 

 mill. (Mild/.-)
