0/«. A beautiful species, and appai'ently very 

 distinct from all tbosc described by Mv. Swainson in 

 the 3GtIi Number of the Journal of Science, Litera- 

 ture and Arts. It differs from A. effiisa, tbe only 

 one with nliicli, on account of its large aperture, it 

 could be confounded, in the following particulars : 

 it is a much less slender shell, it is not banded with 

 white, it has not a deep groove above the varix of the 

 columella, it has only a single belt above the said 

 groove, nor has it any tooth at the base of the outer 

 lip.

(J/)s. A very beautiful Olive, and apparently very 

 distinct ; the pale ground colour is finely relieved 

 by the two dark brown bands composed of triangu- 

 lar fuscous spots and larger intermediate rich dark 

 brown blotches. We have never seen any other 

 specimens of this Olive than those contained in this 

 collection, nor are wc acquainted with its locality.
