HELIX. 71 



glossy, yet not polished, of an uniform greenish olive 

 colour, with rather indistinct longitudinal wrinkles, which 

 are partially concealed by the short and scattered hairs, 

 that clothe the entire exterior. Spire short ; apex obtuse; 

 whorls four, well rounded, moderately raised, rapidly 

 enlarging, the last swollen. Aperture rounded crescent- 

 shaped, as high as broad, occupying about one half of the 

 total diameter. Peristome simple acute, spreading and 

 a little reflected near the umbilicus, which is small but 

 deep. Base rounded. Diameter a quarter of an inch. 



The animal is said to be grey above, yellowish on sides 

 and foot, with dusky head and tentacula and a dark band 

 on each side of neck. 



This is one of our rarest snails. Guernsey (E. F.) ; on 

 hills near Torquay (S. H.) ; Magavissey (Couch) and 

 Pendennis (Cocks, Benson) in Cornwall ; Devon (Bel- 

 lamy). JMr. Lowe of Nottingham has lately sent us 

 specimens found by himself at Stan ton-on-the- Wolds, a 

 very anomalous locality.
