REMARKS

The original publication is the plate, with the name in the legend on the plate, published in the fifth livraison of plates of the Dictionnaire, with the name and authorship given on the reverse side of the front cover of the livraison. The shell illustrated is therefore the holotype by monotypy. The shell in MNHN 24513 is from Deshayes’ collection and matches the shape of the shell illustrated extremely closely.We consider this to be the holotype.The other shell that was with it in the original lot (MNHN 4529), and now retains this catalog number, has no nomenclatural status.

The shell in MNHN 5145 has a label in Deshayes’ hand indicating it to be the “ type ” of Ampullaria polita . However, it has no type status because the name A. polita Deshayes, 1830 (p.31) was introduced as an unnecessary replacement name for A. virescens and is therefore a junior objective synonym of A. virescens , with the same name-bearing type (ICZN 1999b: art. 72.7). For further discussion see A. polita .
