Stat. 116. West of Kwandang-bay-entrance. 72 M. Fine sand with mud. i Spec. 



Shell elongately-ovate, white, with traces of yellowish-brown on upper lirae and near the 

 base, covered by a yellowish epidermis, which is lamellose and pilose. Whorls about 7, of which 

 probably 2 nuclear ones are smooth ; subsequent whorls convex, even inflated at some distance 

 from the deep suture. Sculpture consisting of numerous concentric ribs, about 2 i on penultimate 

 whorl and strong spiral lirae or ribs, crossing the concentric ones, about 19 on last whorl and 

 canal, giving to the surface a cancellated appearance, moreover the shell has conspicuous lines 

 of growth ; last whorl slightly contracted towards the base. Aperture elongately-ovate, rounded 

 above, ending below in a rather narrow canal, slightly directed towards the left; peristome 

 rather thin, undulate by the termination of the external lirae, thickened and strongly lirate 

 interiorly, with 1 2 lirae of which the basal one bordering the canal, forms a tooth, columellar 

 margin concave, with one strong and two fainter plicae towards its base. Interior of aperture white. 



i\lt. 26, lat. 13; apert. alt. 13, lat. 5 Mill. 



I know no species with which to compare the new one ; as the operculum and the soft 

 parts are wanting, I was in doubt even about its generic position, the more so as the rather 

 conspicuous tooth at the base of peristome puzzled me. Mr. Smith who compared the shell for 

 me in the British Museum, declared it to be a Tritonidea. On close comparison I find a few 

 species of that genus which have traces of a tooth on the peristome, but no one where its 

 place is so near the base.
