which is w hite and striated within, and less open than in C. mala- 

 haricuni; aperture a little ol)lique, ohlong ; peristome, when adult, 

 double, not dilated, continuous, before maturity simple, thin, and 

 a little interrupted at the apex, where it touches the penultimate 

 whorl ; operculum a little retracted, a little concave externally 

 from the slight elevation of the margin of the outer shelly portion, 

 closely multispiral, with a moderate transparent nucleus : length 

 1 inch [3-5 mm.], greatest diameter ^ inch [3 mm.]." (Beddome.)

 It is stated to be a glabrous species with markings similar to those 

 found in C. maJaharkmn; but it is much larger and more conical, 

 not at all depressed, less prominently striated, the umbilicus 

 differently shaped, and with a different operculum.

Original description : — " Shell prominently umbilicated, turbi- 

 nate, with a conical blunt apex, inconspicuously spirally lirate, 

 epidermis glabrous, yellowish, with obhquely vertical bright chest- 

 nut bands and a very inconspicuous vertical striation ; whorls 5, 

 convex or subaugular, the lowest with two inconspicuous lines or 

 ribs along the region of the periphery, and sometimes a third still 

 more obsolete between them and the suture ; penultimate with two 

 carinations, the lower one almost touching the sutiu'e and some- 

 times obsolete, antepenultimate inconspicuously iniicarinate ; um- 

 bilicus somewhat angled at the entrance, smooth within ; aperture 

 nearly vertical, circuhir ; peristome subdouble, continuous, incon- 

 spicuously angled or crenated at the exit of the two carinations 

 of the lowest whorl; operculum as in C. (inamallayanum : lengtli 

 i inch [2-75 mm.], greatest diameter ^ inch [3 mm,]." 



Hah. Ceylon : Kambaddi waterfalls {Beddome). 



"Very like C. anamallayanum, but distinguished under the 

 lens by its much more prominent though still inconspicuous cari- 

 nation ; it is also of greater diameter with reference to its 

 length." {Beddome.) 



In 1871 H. Nevill published a CyatJiopoma ceylanicum in his 

 Enum. Helic. Pneum. Ceylon, but no description or figure was 

 given and Beddome's name is consequently not thereby in- 

 validated.
