This is the only genuine freshwater shell that I have seen from 

 either the red or cor. crag. I have but one specimen, procured from 

 undisturbed crag five feet below the bottom of the incumbent sand. 



PI. V. f. 12. is an enlarged representation of a very minute sini- 

 stral shell, not more than ;|^th part of a line in diameter, somewhat 

 resembling in outline Planorbis corneus, but too small to be the fry, 

 I think, of that species ; moreover it has the appearance of a spire 

 more elevated and a deeper umbilicus than in any species of that 

 genus that I am acquainted with, and is probably a marine shell. 

 Three other specimens of about the same size were in my cabinet 

 six years ago, but are now unfortunately lost.

The increasing importance attached by naturalists to the 

 class of Zoophytes may seem to justify any attempt, however 

 humble, tending to elucidate their local distribution. I feel, 

 therefore, encouraged to submit to the readers of this Journal
