One of the most choice and magnificent shells at present know n 

 There are few cabinets of distinguished eminence in which the species 

 does not occur in the earlier stages of its growth, but it is rarely met 

 with in that adult and perfect state in which it appears in the annex- 

 ed plate. ■ - ^ >■'■■ ~ 



When in the younger state, the broadly-expanded or wing-like 

 lip, so conspicuous in its final growth, is wholly wanting, the lip 

 terminates in a very thin acute edge, and this, owing to its brittle 

 texture, is not always found extremely perfect. After the shell has 

 attained to a moderate size, this lip begins to thicken and enlarge, 

 increasing in dimension as the growth proceeds, and at length 

 becomes of a very considerable size in proportion to the magnitude 

 of the whole shell. In its most perfect, or full-grown state, the lip 

 turns inwardly, forming a pretty thick margin, which is usually 

 striped or banded, and adds much to the strength as well as beauty 

 of the full-grown shell. _ ^ ,

 of the species originally in the Museum of the late Sir Ashton Lever,-
