Dr. Pfeiffer refers tWs shell to the Buccinum striatum of 

 MuUer, but there is no mention of the characteristic striped 

 painting in the description of that author ; neither is 

 there any account of the delicate tinge of yellow or rose 

 colouring which characterizes the species referred to it by 

 M. Deshayes, namely, the Achatina rosea. There is no 

 doubt, however, of the shell under consideration being 

 identical with that figured by Chemnitz under the head of 

 B. strMum in Conch. Cab. vol. ix. pi. 120. f. 10.30.

This fine species from the collection of .1. Dcunison, Esq., 

 approaches nearer to A. Soioerbyana than to any hitherto 

 described.
