6 INTRODUCTION. 



contracts them again before it has completed its 8 

 or 9 whorls, and forms its perfect mouth. When the 

 animal has formed whorls enough of the tapering 

 kind to contain that part of the body which was in 

 the small whorls, it secretes a conical tapering 

 septum between them and the slender ones, and 

 the top falls off from want of connection with the 

 animal. (This is well figured in Philippi, Sicily, 

 t.8. f. 14.)

This shell was first introduced into the Fauna, 

 and indeed first described, in 1822, by Mr. Miller, 

 who found it in some pine-beds at Bristol ; it is 

 also common in the same situations in the neigh- 

 bourhood of London, especially in Kensington Pa- 

 lace garden ; and has been found near Manchester 

 by Mr. Williamson. It was first observed by the 

 late Mr. Drummond, the botanist, in 1816, who 

 was in the habit of feeding them; and when he 

 wanted a supply, he merely placed a flat board 

 upon the surface of the tan, and left two or three 

 small dead worms beneath it, and never failed of 

 finding it covered with them in a few days. Fleming,
