HELIX. 135 



Jeffreys, Linn. Trans, xvi. 507. Monacha sericea. Fitz. 

 Syst. 95. Fruticola sericea. Held. Isis, 1837, 914. 



Inhab. moist woods and hedge banks. 



Animal pale yellowish white ; head and tentacles 

 grey; mantle beautifully speckled with black, the 

 black blotches being larger towards the upper extre- 

 mity, and giving the higher whorls of the shell a 

 mottled appearance when alive ; the foot is short and 

 thick. 



Shell a quarter of an inch in diameter, and as 

 much high, pale horn-colour, frequently a little rufous 

 about the mouth, extremely thin and light, clothed 

 with a very fine down enlarged at the base, which, 

 when worn off, leaves the surface glossy and minutely 

 granulate like shagreen; aperture crescent-shaped, 

 rather wider than long, very thin, and reflected only 

 at the umbilicus, which is extremely small. The 

 larger volution is-well rounded, without keel or band, 

 and the internal rib only visible in full-grown speci- 

 mens. 



This is evidently not the H. hispida of the con- 

 tinental writers, nor the H. sericea of Miiller or 

 Draparnaud.
