The specimens vary considerably in size, colour, more or less ribbed spire and even in 

 the distinctness of the sutural canal. The species is no doubt allied to N'. taenia and ttnicolor^ and 

 I think has been often mixed with these species. Kuster is in doubt if Reeve's fig. 18 belongs 

 to this species. I should incline to think that Reeve's fig. 1 7 fzuticolorataj agrees better with 

 this species, than with Kiener's B. unicolorum, at least Kiener's figure shows no trace of a 

 canaliculate suture, as Reeve's fig. 1 7 does, and Kiener's description does not mention it, 

 moreover the shell of Kiener is much more elongate. I have united those specimens which 

 show a distinct, though not always large channel, without regard to the other, most inconstant 

 characters, as size, colour and number of ribs, which merge insensibly into each other.
