Adams describes the species as smooth, Watson and Pilsbry mention fine, remote, 

 spiral striation; the Siboga-specimen is in very fine condition, it very well agrces with Pilsbry 's 

 figure, but I should not call the striae remote, though they are narrower than the interstices, 

 they are not visible on that figure. Kobelt has givcn a coloured figure of the species, on 

 plate B of his Bui/acca, in the second edition of the Conchyhen-Cabinet ; this dorsal view, with 

 the animal, but without description, shows a more remote striation, but is less characteristic 

 than the beautiful plates, representing the empty .shclls in Kübelt's monograph.

.Shell rather large for the genus, oval, thick, white, with raised .spire. Xuclear whorls 

 broken, remaining whorls about 3, (worn), scparated ncar llic apcrture and probably higher 

 on, by a narrow, channelled suture ; last whorl contracted below the suture, then Hatly conve.K, 

 rounded near the base. Sculpture consisting of very fine radiating or growth-striae, stronger at 

 intervals, more conspicuous on upper part of last whorl, and numerous spiral striae, which are 

 raised on the upper part, impressed on the lower part of body-whorl, the interstices are con-
