0/js. A beautiful species, and apparently very 

 distinct from all tbose described by Mr. Swainson in 

 the 36tli Number of the Journal of Science, Litera- 

 ture and Arts. It differs from A. effusa, the only 

 one with which, 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.

 lis trigonibus fiiscis, confertis notata : interstitiis 

 fasciarum maculis trigonibus fusco-nigris eonsper- 

 sis : spira brevi, mucronata ; cingulo basali fusco 

 maculato ; aperturd intus pallide fulva ; colu- 

 mellee plicis regularibus, basi earned : long. l^V 

 lat. iV uiic. 



Obs. 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. AVe have never seen any other 

 specimens of this Olive than those contained in this 

 collection, nor are we acquainted with its locality.
