PLATE XIII. 



Prof. Gmelin, in the last edition of the Systema Naturae, enumerates 

 no less than thirty-one varieties of this beautiful land Shell. Da Costa 

 describes six principal varieties in his British Conchology *. Some of 

 the kinds are rare, others extremely common, hving in trees, hedges 

 and gardens. It is a widely diffused species being found in every part 

 of Europ^e as well as Great Britain. 



♦ I. Uniform, of a pale citron colour, or yelIo7V of different shad a : the miuth finely 

 bordered within and without, with a dark brown, and with a brownish shac'e or cloud 

 on so much of the body wreath as lies within the mouth, or from the outer lip quite 

 across to the edge of the pillar. Pretty frequent. 



2. Uniform, oC nfesh colour oi different shades, with the mouth in like manner bordered 

 with dark brown j and the body wreath also shaded exactly the same as the last. Not 

 ■very frequent. 



3. Uniform, of different degrees oi brown, with the same circumstances. Common. 



4. 1 he ground yellow or greenish yelkw of dfferent shades, with a regular single fpiral 

 girdle, or according to the turn of the wreaths, in the very middle of each wreath, with 

 the brown border round the mouth, and the shade or cloud on the body. Pretty frequent. 



5. the ground flcjh cohur of different shades, variegated in like manner with a single 

 girdle, the border round the mouth, and on the body. Not veryfnquent. 



6. Mi.vy dark-brown spiral girdles on the yellow,fe/h, or brtnvnish grounds, sometimes to 

 fii-e girelks at least on the body wreath ; sometimes only four. Thefe girdles are of 

 different breadths, some being very narro^u, like streaks, others broader, like belts j 

 and others so extremely broad as to cover the parts, and make the ground colour only appear 

 in girdles. They are also not equidistant or regularly set ; but the very bruad girdles lie most 

 generally on the upper part of the shells. These girdled iorts are the most frequent or 

 common. Da C^sta Br. dnch, p. 78.
