HELIX. 39 



H. SERICEA. Draparnaud. PL VI, fig. 11. 



Somewhat globular, transparent, yellowish horn or white colour, 

 closely downy ; six volutions ; umbilicus small. 



Helix granulata, Gray, Brown. 



This beautiful little shell may be readily distin- 

 guished from hispida, which it most nearly resembles, 

 in being a lighter colour, having the hairs finer and 

 more closely set, and the spire not nearly so much 

 depressed. The animal is greyish about the head and 

 tentacles, the mantle marbled with black. This species 

 includes sericea and granulata of Gray, which appear 

 to be but variations of the same shell, probably arising 

 from some natural or local circumstances. Diameter 

 the third of an inch. * 



Hob. Found in similar situations to Jiispida; delight- 

 ing in luxuriant vegetation in damp woods, &c. The 

 species is widely distributed but local, we have met 

 with it abundantly in woods near Middleton-one-row, 

 Durham, and in Bilsdale, Cleveland. It is recorded as 

 being frequent in the south and west of England. 



H. LAMELLATA. Jeffreys. PL VI, fig. 13. 



Shell small, trochiform, with close set longitudinal lamellae ; mouth 

 lunate ; umbilicus deep. 



The similarity between this species and fulva, is 

 greater than between it and aculeata, though perhaps 

 more properly speaking it holds an intermediate place 

 between the two ; the whorls are not so close as those 

 of fulva, and it is not so conical, being much blunter 

 in the spire ; moreover it is covered with longitudinal 

 ridges, and has a round instead of a flat bottom. About 

 the tenth of an inch in diameter. 



Hob. This shell is far from common, having only 

 been found in few localities ; it prefers a damp situation 

 amongst decaying vegetable matter. It is confined to 

 the north of England, but generally distributed over 

 Ireland. We have found it in Airy Holme Wood, 

 Cleveland, and other places.
