HELICID.E. 155 



Animal reddish, very polished; tentacles longish. 



Shell very like the former, but differs in being 

 rather larger, the umbilicus wider, and the hairs 

 further apart, and much more deciduous, which 

 makes it often appear smooth, except near the sutures 

 and umbilicus. 



Mr. Jeffreys, after examining many hundred spe- 

 cimens from different localities, is inclined to think 

 that it must be referred to H, hispida. (Linn. Trans. 

 xiii. 510.) 



Mr. Alder observes that this may be a variety of 

 H. hispida, as was supposed by Mr. Jeffreys, but is 

 stronger, and with the hairs more deciduous than 

 the usual form of that species. It is very generally 

 diffused, commonly taking the place of Helix glabella 

 (H. rufescens), in situations where the latter is not 

 found. (Alder, Mag. %. B. ii. 107.) 



Mr. Alder also refers to H. circinnata of Ferussac, 

 which Rossmasler regards as a distinct species. 



39*. 21*. HELIX depilata. Bald Snail, (t. . f. 135*.) 

 Shell somewhat globular, depressed, pale, bald ; 

 whorls rounded, concentrically grooved ; mouth 

 lunate; peristome thickened, white; umbilicus 

 moderate. 



Helix depilata. Pfeiffer, i. 33. t. 2. f. 18. (?) ; 

 Alder, Mag. Zool. Sot. ii. 107. 



Inhab. hedges and wet places. 



This species is very like the former, but quite des- 

 titute of hairs in all its stages ; it is much smaller in 

 all its parts than any of the varieties of H. rufescens. 



Mr. Alder states that his specimens agreed perfectly
