This species, of which I possess myself specimens from 

 Celebes, seems to have been overlooked ; in colour and 

 shape it resembles N. incerta von dem Busch and N. umlaa- 

 siana Krauss, also some dark varieties of N. polita var. 

 Rumphii Reel. It may, if complete, be easily recognized 

 by the operculum, which is divided by a groove. A similar 

 operculum is figured by von Martens in the 2^^ Edition 

 of the Conchylien-Cabinet of Martini and Chemnitz, Plate 

 A, fig. 13, as belonging to N. alveolus.
