the older concliologlsts often confounded it, by there 

 being no appearance of any oblique fold on the 

 pillar, 



Montagu justly observes that the animal, like the 

 other Limaces possessing four tentacula, is herma- 

 phrodite, and sometimes unites as late as the month 

 of August. {Test. Brit. 398. and Sup. 139.) 



It is named from the transparent amber colour of 

 its shell. 



They are found in damp marshy places on the mud, 

 water-flags, &c., but are scarcely to be considered as 

 amphibious, for they are never found in the water, 

 like the Limnm or Pond snails. The jaw is thick, 

 with a central prominence ; the teeth are truly 

 helicine in their conformation, the central strong, 

 apex three-pointed, the lateral thifck, robust, with 

 two unequal oblique lobes. 



The eggs are globular, yellowish-hyaline, adhering 

 in agglutinated masses to plants and stones. 



Epiphragm thin, membranaceous, transparent.
