The suggestion of Mr. J. Brazier, that this species should live in deep water, has not 

 been confirmed by the collection of the Siboga-Expedition. The specimens vary considerably in 

 colour-pattern, that from Stat. 77 is much bleached, those from Stat. 99 have a broad brown 

 band in the centre of the back, bordered by narrow zones of a light colour and a few spiral 

 rows of brown blotches. A very young specimen from that locality, with scarcely any traces of 

 teeth, is uniformly brown on the back, whitish near the produced spire and along the right 

 margin of the aperture; those from Stat. 109 have but a few brown blotches near the dark 

 central band (broken up in one specimen), that from Stat. 1 64 has only a single indistinct band ; 

 the specimens from Stat. 3 1 3 are very similar ; these differences seem to be only individual, 

 I have failed to recognize one of the described varieties amongst them.
