HELIX. 135 



Jeffreys^ Linn. Trans, xvi. 507. — Monacha sericea. Filz. 

 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 oiF, 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.
