One of the specimens from Banda and one from the Saleh-bay are nearly as elongated 

 as Reeve's figure, the other ones are shorter, better agreeing with the quoted figure of Smith 

 and even shorter, one from the latter locality is darker (brownish); all display the brown bands. 

 The beautiful operculum is thin, yellowish with a blackish spot on the hinder part and a black 

 transverse line, the edges are dentate.

As the only specimen, which agrees in every respect with the description and figure is 

 not adult, and I consequently could not make out, to which section of the genus it bclongs, 

 moreover the figured specimen seemed to have a thin peristome, I asked Mr. Smith about 

 this question, who writes: "Not having an adult specimen, it is difficult to clecide the section 

 to which N. diluta belongs. It seems rather allied to Hebra' The operculum is thin, corneous, 



with plain edges.
