Jeffi'eys^ 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 blacky 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 Muller or 
Draparnaud.
