258 ZOOLOGY. 



Most of the Cone-Shells are covered with an epidermis, 

 under which, the surface bears a most beautiful polish ; all 

 the species are marine, and are generally found on rocky- 

 coasts.

A most beautiful family, mostly marine, inhabiting the sand 

 at the bottom of the sea, from whence they are often thrown 

 after violent storms ; most of the kinds possess an exquisitely 

 fine natural polish.

Shell convolute, sub-oval, unarmed ; aperiure oblong, smooth, 

 longitudinal, entire at the base; columella smooth, 

 oblique. Plate 5, fig. 22. 



The Dippers are found inhabiting the sea, rivers, lakes, and

 thin; the marine kinds are sometimes found in shallows, 

 during the recess of the tide.
