B. lotophaga, according to Morelet, is a cylindric shell 

 which quite resembles Grlandina. The surface is engraved 

 with fine, regular deep striae, imperceptible on the first whorls, 

 and is covered with a thin uniform ochre-yellow cuticle, 

 glossy in the young, and with a green tinge; but this gloss 

 with a silky appearance diminishes with time, the epidermis 

 also being partly lost. Quite rare in collections, this species 

 has up to this time been found only on the He du Prince.

The shell is rather large, oblong or spire-shaped, imperforate 

 or rimate, covered with a yellow cuticle streaked with brown. 

 The summit is rather large, obtuse and rounded, the initial 

 whorl smooth; following whorls are closely rib-striate, and 

 sooner or later decussating spirals appear. This sculpture may 

 continue to the last whorl or become obsolete there. Aperture 

 ovate, the outer lip more or less obtuse, simple or slightly 

 expanded; columellar lip free and built forward, or adnate.
