The body-whorl of the older specimens of this shell is rather roughly 

 striated or wrinkled, the last but one slightly so, and the remaining whorls 

 are quite smooth. The colour is whitish, with purple spots more or less 

 obsolete : the old specimens are sometimes of a dull yellowish white. 

 A specimen is deposited in the British Museum. 



The young shells of this species are of a whitish brown, with darker 

 coloured striae. They are very fragile and semi-transparent.

* Whilst this sheet was printing, the September number of the Annales dcs 

 Sciences made its appearance in England, containing a description of the above 

 shell by M. Sander Rang accompanied by an excellent figure (Annales des 

 Sciences Naturelles, September, 1831, p. 55, pi. 3, f. 1.) It is there named 

 Helix multicolor. In my dccrlption I have considered it to be a Buliuus, but 

 its specific name has been altered to that given to it by M. Rang.
