 Helix nemoralis Var. Linn. Trans, viii. 206.; 



DiUw. Cat. ii. 942. 



Inhab. woods, hedges, and wet shady places. 



Animal reddish, yellowish, or pale grey ; tentacles 

 generally dark grey. (Sturm, t. 22.) 



Shell about a fourth part smaller than H. nemoralis, 

 which in colour and varieties it much resembles ; but 

 is distinguished by its smaller size, in not being quite 

 so convex, in being more polished and thinner, and in 

 the white margin round the aperture. 



Like many other snails, it offers the following mon- 

 strosities : 



1. In the whorls being reversed. (Ferns, t. 36. f. 

 10.) 



2. And in the whole of the spires being more or less 

 separated from each other (Ferus. Hist. t. 36. f. 1 1, 12.) 



In the Annals of Philosophy for 1825, p. 152., I ob- 

 served that there was a difference in the form of that 

 part of the generative organs of Helix nemoralis and 

 H. hortensis called vesicv.la multifida by M. Cuvier, 

 in his dissection of Helix Pomatia ; and further ob- 

 served that this name for the organ gives an er- 

 roneous impression, as in several of the Helices it is 

 simply forked, in others doubly forked, and rarely 

 many-cut, as it is in the edible snail.
