- B. testâ lævi conicâ; spiræ anfractibus quinque; ultimo aliquantulum distorto; albis duabus fasciis ferrugineis inæqualibus; anfractu basali rufo duabus albis fasciis; aperturâ albâ.
- Shell smooth, conic, of five volutions, the last somewhat distorted; white, with two unequal ferrugineous bands; body whirl rufous, with two white bands. Aperture white.
A small though very elegant shell, seldom seen in Collections; nor do I find such a description of it as will identify the species. One figured by Martini, at tab. 134, fig. 1215, comes near it, but differs sufficiently for a specific distinction.
Its precise locality is unknown: a fine specimen exists in my father's collection, who thinks it came from the East Indies; and this is the only one I have yet seen.
The aperture is more round than ovate, and is less than one half the total length of the shell; the outer lip much reflected, and the transverse bands on the spiral whirls nearly obsolete.
