This genus Bruguiere pointed out as a necessary se- 

 paration from the Linnaean G. Buccinum. The Tere- 

 brae are not only distinct from the Buccina on account 

 of the long turreted form of the shell, but also from 

 the peculiar character of the very short columella, and 

 the animal (according to Adanson) not possessing an 

 operculum. They are also readily distinguished by the 

 following marked and peculiar characters: — Shell very 

 long, turreted, and sharp pointed at the summit; the 

 exterior smooth or variously striated, never with spiral 

 ribs or carinations, as in the G. Turritella, to which 

 the general form bears some resemblance. From the 

 G. Eburna they may be known by not having a canali- 

 culated umbilicus, and from the G. Buccinum, in con- 

 sequence of the aperture only occupying a very small 

 portion of the length of Hie shell.
