Figs 8-10

Helix (Cochlogena) atrovirens S. Moricand, 1836: 416 , pl. 2 fig. 1.

Type locality: [ Brazil, Bahia] “ Portao ”.

Label: “ Bahia, M. Blanchet 100”, in Moricand’s

handwriting [78487]; “ Bahia, Moricand”, in Brot’s handwriting [64624].

Dimensions: “11 millimètres de hauteur et 21 millimètres de largeur”; figured specimen herein H 20.9, D 20.3, W 3.4.

Type material: MHNG-INVE-78487, six syntypes (Moricand coll.); 64624, two probable syntypes (ex Moricand, Brot coll.).

Remarks: Moricand did not state on how many specimens his description was based. The shell height as given by Moricand was probably measured with the aperture down on a surface, and is thus not comparable to the way modern dimensions are given. The specimens in Brot’s collection originate from Moricand and are considered as probable syntypes. The current systematic position follows Simone (2006).

Current systematic position: Simpulopsidae , Simpulopsis (Simpulopsis) atrovirens (S. Moricand, 1836) .
