have to repeat here the same labour, but merely to refer to the syn- 

 onymy only where it is absolutely necessary to guide the reader in his 

 search after species. 



Thirty-seven new species have been described and figured in the 

 ' Zeitschrift fur Malacologie' for 1846 ; they were named and placed 

 where they should stand in the completed series. Other species equally 

 new will be described according to natural characters which link 

 them with their congeners: thus will be found completed the series 

 of species that can be at this day admitted into the genus. 



Besides the admissible species, there will remain sixty or more 

 names introduced from different motives into the genus, and which 

 we ought to reject. Of these we shall make an alphabetical list, and 

 introduce a few brief observations to show why we have rejected them. 

 Some are names repeated, others are uncertain species insufficiently 

 described or badly figured, and the rest have been given to species 

 not belonging to the genus. 



The Terebrce have the closest relation to Buecinum, as Concho- 

 logists well know, and it fell to Lamarck to introduce two species of 

 true Buecinum amongst the Terebrce. And the reverse has also 

 taken place, for some true Terebrce have been ranged with Buecinum. 

 These facts show how nearly these two genera are related ; and so 

 it seems natural to place first the species most nearly allied to 

 Buceinum, and lastly those which are farthest removed from them.

Apres avoir donne ce nom a cette espece dans le premier volume 

 de ses Mollusques de Sicile, M. Philippi la reunit a la T. aeiculata 

 dans le second volume du meme ouvrage. Nous aurions suivi cet ex- 

 emple si deja plusieurs fois on ne nous avait mentionne cette forme 

 dans le Mediterranee. Avant de supprimer I'espfece il est convenable 

 d'attendre de nouvelles observations.
