FUSUS. 



A monograph of this genus has been i)ublished by Mr. G. B. 

 Sowerby in the " Thesaurus Conchyliorum," since the appear- 

 .•ince of the pages comprising the Fusidiie in the present volume. 

 'I'Jie " Fusus " of Mr. Sowerby is an assemblage of shells belong- 

 ing to a number of genera, omitting many species and misinter- 

 preting others, and (inevitable under such circumstances) 

 describing as new, a number of forms which scarcely present 

 sufficient claims to novelt}^ The figures are superb in their life- 

 like delineation of the shells ; indeed, in this respect Mr. 

 Sowerby is without a rival, for to great technical skill he unites 

 a scientific knowledge of the subjects he delineates. I give 

 below the names, localities and copies of the figures of the sup- 

 posed new species, together with opinions and suggestions con- 

 cerning them.
