 much more swollen, and covered upon their whole surface with 

 very fine and very close transverse striae ; suture very ap- 

 parent, and a little canaliculated ; aperture white, ovate, nar- 

 rowed at its tipper part, dilated inferiorly ; right lip thin, 

 ornamented interiorly with numerous transverse striae ; colu- 

 mella smooth, arcuated at base, covered throughout its whole 

 length with the left lip, the base of which is a little thicker. 

 The surface of this shell is reddish or violet-colored, with

 Inhabits 



This shell so much resembles the preceding that we have 

 brought them together ; the only difference, which can be ob- 

 served, is in the form of the lowest whirl but one, which is more 

 convex, and larger ; it has also finer and more numerous trans- 

 verse striae.
