PLATE cm. 



author. In point of size, it is rather less considerable than our 

 Helix Pomatia, the largest of our British Helices, but it is equal to, 

 or rather exceeds, in this respect, the larger growth of the Common 

 Garden Snail The shell is somewhat ovate in form, globose, and 

 ventricose; the colour a pale yellowish, or sulphureous tint, but 

 is so closely encircled with reddish orange bands and lines, as to 

 convey the idea of an orange-coloured shell, encircled with pale 

 yellow lines. A broad band of the same pale yellowish tint traverses 

 the upper or dorsal surface, just below the middle, but which becomes 

 narrower and less conspicuous as it passes round the lower surface 

 towards the upper segment of the lip. The margin of the lip is of 

 a pale rosy colour, above and beneath, and the pillar of the same 

 hue. 



This shell is of extreme rarity, and may possibly be unique : 

 it has been lately added, at a considerable price, to the conchological 

 cabinet of Mrs. Mawe, and is introduced into the present work by 

 her permission and kindness. The native place is unknown : we 

 name it Festiva in allusion to the gaiety of its appearance.
