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 strie. They are very fragile and semi-transparent.

* Whilst this sheet was printing, the September number of the Annales des 
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, pl. 3, f. 1.) It is there named 
Helix multicolor. In my decription I have considered it to be a Bulinus, but 
its specific name has been altered to that given to itby M, Rang.
