 the very close and minute development of longitudinal striae.

It is probable, from the faintly-banded appearance of this shell, that 

 this is but the pale variety of a darker type.

This is the species which Dr. Pfeiffer has assigned to the Bulimus 

 Mahogani of Sowerby, Conch. Illustr. f. 59 ; a species of the B. rosa- 

 ceus or hcemastoma type, of which I can find no description or tidings. 

 The species under consideration will be found, on comparison with 

 Sowerby' s figure, to be of a more oblong form, more acuminated at 

 the apex, and very peculiarly indented round the upper sutures, re- 

 minding one very much of the indentations in the shells of Phorus.

A thin shell, approaching in form and colouring to the Bulimus 

 nux, from which it differs in being of hghter structure, and having a 

 more rounded aperture.
