naeus fuppofes tliat this fpecies may be a variety of the 
lafl ; but, according to Mr Montagu, the form of the 
fhell, the ftru&ure of the animal, and its habitat , are 
always diflinCl. Linnaeus fays, that this fpccies is 
found among wet mofs. Mr Montagu found it only in 
ditches, and in a place occafionally overflowed by the 
river Avon.

(b) In fome of the fpecies belonging to this genus, it appears that the animal poffeiTcs different characters 
from thofe of the limax, and particularly that which inhabits the bulla lignaria, a Britifh fhell, which is furnifh- 
ed with a gizzard, of a teffaceous nature. See Lin. Tranf. vol. ii. p. 15.
