1(» Mt. Oriz and Moka, Manritiu.s. — Only distinguished from its European 

 close ally, A. foUiculu.^, by the more tumid last whorl and broader 

 aperture. It lives gregariously under large blocks of stone ; the 

 animal is bright-yellow and very active. A single one of the living 

 specimens which I found was reversed. Has the European form been 

 found sinistral ? The anatomy of one of these specimens is described 

 by Semper, (Heft III Philipp. Moll., p. 135,) as a shell sent by me 

 labelled " Glandina vesiculata, Bens." ; this was the name under 

 which the) form was known at Mauritius, and used by me before I 

 had access to any conchological works.
