The shell of no animal is more common as a subject of curiosity in 

 this country, from the largest to the smallest species, whether foreign or 

 domestic ; yet no animal is less understood, or has been more rarely seen 

 and described, than its inmate. 



It is one example also, that, however abundant such creatures may 

 be in their native haunts, they are found rare to us, desiring to obtain 

 them alive, and to render them the subjects of observation. 



The transitions of the animal tribes to each other, skilfully shewn in 

 their anatomical structure by distinguished authors, are overpassed by 

 those less sensible of the wonderful construction of the living frame, and 

 who confine themselves to the study of living creatures exclusively. 



Length of the shell half an inch ; figure approaching an ovoid, 

 deprived of the usual opening, in place of which is a wide longitu- 

 dinal fissure, occupied by its tenant. The whole surface is finely indented 

 by grooves, penetrating the edges of the fissure. Colour whitish ; surface 

 resembling porcelain. 



The tenant of the shell is a yellow Limax, of remarkable dimensions 

 compared with the size of its dwelling, extending an inch and an eighth, 

 or above twice its length. Head terminated by a syphon or snout, fold-

 rather slender, long tentacula, having a black eye externally on the ba.se 

 of each, are in front. A dark cloak, unseen when the animal is in retreat,
