A71 exotic (/from Malta or the Grecian Archipelago) sjiecies, 

 introduced by Montagu, on the authority of a Mr. Swainson, who 

 supposed it identical with soine shells he had seen taken from Hyde 

 Park and Battersea Fields. Our description is taken from Turtons 

 example. 



ZUA. Leach. 



Shell spiral, cylindrical, elongate-ovate, smooth, and 

 shining with a vitreons lustre, derived from the polished 

 epidermis. Mouth ovate, peristome entire, simi)le, thick- 

 ened, but not reflected. Columella imperforate. 



Animal closely resembling that of Helix, and having a 

 similar dentition ; the central denticle of each series is very 

 minute. 



The brilliant little shells composing this group, have a 

 peculiarity of habit which entitles them to be kept 

 generically apart from Bulimus as much as Puim or 

 Baled. Comparatively few species have, as yet, been met 

 with. They represent (in conjunction M'ith the next 

 genus) the Pibpintz among the C^clostomidfe.
