Helix caperata (The Black tipped Snail) Monlayu. 

 Fiaures oS and 59. 



la the latter end of the last century Dr. Pultcncy 

 added this snail, in his catalogue of Dorsetshire shells. 



Shell globular, but slightly depressed, apex blunt, 

 aperture small and crescent-shaped, the margin beiny; 

 white in the interior. A moderately-sized and deep 

 umbilicus. Shell yellowish straw-coloured, with browu 

 bands, and raised wrinkles. There are six convolutions. 



The ordinary size is three-eighths of an inch. In 

 this neighbourhood it is not so large, four lines in 

 length being a fine specimen. Professor Forbes says 

 his largest example is more than five lines in diameter. 



The colour of the animal is grey, with darker tenta- 

 cles, from which a dusky belt is continued down the 

 neck. 



Specimens of a very pretty variety have been sent by 

 Mr. Bridgman, of Norwich, found at Thorp, in that 

 neighbourhood. This variety resembles Helix virgata 

 so closely, being banded like that species, that at first 

 sight it would betaken Tor ihc Zoned Snail ; a more 

 attentive inspection shows the snail to be a variety of 

 H. caperata, as it is considerably more depressed, and 

 is very plainly concentrically striated, whilst the H. 

 virgata is devoid of strioe. Fine specimens of this 

 variety are five lines in diameter. 



Another variety has been found at Stanton-on-lhe-
