Deshayes, Anim. sans vert. vol. x. p. 192. 

 Buccinum semitnm Dufresue. 



Sai. St. Elena, West Columbia. 



The name pristis has been given to this singular species 

 by M. Deshayes in consequence of that of serratmn intro- 

 duced by Dufresne being pre-occnpied in reference to a 

 fossil species ; it was originally dedicated by Mr. Gray in 

 manuscript to Lady North, Buccimnii Northite, but I can- 

 not learn that this name ever reached publicity. 



Species 40. (Mus. Cuming.)

Hob. Isle of Annaa, Pacific Ocean (on the reefs at low

 An interesting new species abundantly distinguished 



from the two which follow by its shorter and more inflated 



growth, smooth siu^ace and peculiar style of painting.

 Purpura Francolinns, Lamarck. 



Hab. Isle of Annaa, Pacific Ocean (on the reefs at low 

 water); Cuming. 



This may easily be distinguished from the foregoing and 

 following species, by its minutely cancellated sculpture and 

 delicate tone of colouring.

Buccinum sertum. Buc. testd ovato-oblongd, spird brevi, 

 subobtusd, anfractiius superne leviter concavis, transver-

 the upper part, transversely granosely striated, striae 

 sometimes rude sometimes fine, last whorl inflated ; 

 aperture large, furnished at the upper part with two

 of the preceding ; the sculptm-e sometimes coursely, some- 

 times delicately engraved.
