Achatinella (Leptachatina) dimidiata Pfeiffer, P. Zool. Soc. London, 1855, p. 205. 
The Z. cingula Mighels is unknown to me; I quote the following from Mr 
Hartman, “Achatinella dimidiata Pfeiffer, equals cznguda Migh. in coll. Newcomb ex 
Auct. The figure of this shell in Chemnitz [i.e. Conch.-Cab. Budimacea, pl. LXvI. 
figs. 5—7] does not represent the species, but equals an Amastra.”
