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.')

 F.) xi, p. 158. 



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.

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 3%- 

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

 mill. (Mild/.)
