An insignificant little form with no striking characters; there being no other 
species recorded from the Islands, I venture to give these shells a name; they are 
probably not adult.

Fam. MELANIIDAE. 
Mevania Lamarck. 
The genus appears to have been first put forward by Lamarck in 1799 (Mém. 
Soc. Hist. Nat. Paris, p. 75) and to have been also characterised by him in 1801 (Syst. 
An. sans Vert. p. 91). In both cases the species named by him was A/elanza amarula 
Lam., which is therefore the type.
