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. £14.) .

Achatina clavulus Sow. Gen. t. f. B. clavulinus Potiez, Gal. 1. 186. t. 14. f. 9, 10. Inhab. Guadaloupe; naturalised in Bourbon and England. 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 smal] dead worms beneath it, and never failed of finding it covered with them ina few days.
