shell, of ordinary size and with the same character of the aperture,, 

 occurs, showing an interesting and gradual change in form ; the 

 operculum is also different, being pale coloured, multispiral, and 

 flatly concave in front. This form is in this respect much nearer 

 to A. digitatus, and might be separated under the title var. 

 subdigitatus." (Godwin- Austen.) 



Subsequently the author appears to have somewhat modified 

 his views with regard to the Shengorh Peak form, for in 1914 he 

 observed that it is a mere variety, differing in its smaller size, 

 more depressed and rounded spire, and liner costulation, at the 

 same time substituting the name var. nana.
