In stagnant ditches, England, North Wales, Ire- 

 land. Locally and periodically abundant ; living on 

 the roots of duck-meat. 



Montagu described the animal as large in pro- 

 portion to its shell, like many of the Buttce ; and he 

 thinks it might be placed in that genus. It is 

 covered with a tenacious slime, and is of a pale 

 dull yellow colour, sprinkled with bright brimstone 

 spots ; the tentacles are very broad at the base, and 

 flat ; eyes small, placed at the base of the tentacula 

 on the inside ; front broad ; the foot spread and mo- 

 derately long: when the membrane that usually 

 covers the shell is withdrawn, the colour of the 

 animal beneath the transparent shell gives it an ap- 

 pearance of highly polished tortoise-shell. In the 

 young shell the mantle is more developed, and al- 

 most entirely covers the shell. 



Shell about half an inch in diameter, extremely 

 thin and transparent, of an amber or yellowish horn- 

 colour, somewhat orbicular, with the outer lip much 

 expanded ; spire consisting of three and a half volu- 

 tions ; the smaller one lying nearly flat on the larger
