" This shell is easily distinguished from its congener D. pachy- 

 cheilus, Bens., by the greater tenuity of the aiitepeuultimate whorl, 

 the absence of sculpture on the lower whorls and the more 

 prominent angle at the left lower corner of the peristome. This 

 last cliaracter in B. semisculpta is rather stronger than appears in 

 the figure. The present species is much more closely allied to 

 I), dijjiocheilus, Bens., whicli it resembles greatly in sculpture and 

 form. Tiie principal distinction is in the peristome which is much 

 less developed in D. semisculpta, the pai'ietal callus being quite 

 thin and appressed instead of standing out from the last whorl as 

 in that species. The mouth also is larger in proportion, the angle 

 at the base of the columellar margin more salient, and the spire 

 more acuminate." [Blanford.)

 rimate, thin rubescent sfraw colour, diaphanous ; sculpture very 

 fine, close, filiform, shewing well on all the whorls ; spire with 

 sides slightly convex, apex subacuminate, conic; wliorls 6, convex, 

 penultimate and ante-peiiultimateof very nearly the same size, the 

 former being slightly the largest and more tumid ; last whorl 

 constricted in front of peristome above the aperture, ascending ; 

 aperture sub-vertical, coluuiellar margin much rounded, tlie tooth 

 very small, and in some old specimens is hardly to be detected : 

 peristome thin, double and close, the outer \ery slightly expanded,
