Helix (Cochlogena) heterogramma S. Moricand, 1836

Figs 84-85

Helix (Cochlogena) heterogramma S. Moricand, 1836: 437 , pl. 2 figs 15-17.

Bulimulus heterogrammus . – Pilsbry, 1898 [1897-1898]: 321, pl. 26 figs 81-82.

Rhinus heterogrammus . – Simone, 2006: 127, fig. 407.

Type locality: [ Brazil, Bahia] “avec la précédente [les grand bois à la Caxoeira]” .

Label: “ Brésil, le bois de la Caxoeira”, in Moricand’s handwriting.

Dimensions: “Longueur, 13 mill.; largeur, 5 mill.”; figured specimen herein H 12.5, D 5.95, W 6.2.

Type material: MHNG-INVE-64598, four syntypes (Moricand coll.).

Remarks: Moricand did not mention on how many specimens his description was based. Pilsbry (1898 [1897-1898]) placed this taxon under the heading ‘Species of uncertain subgeneric position’, and suggested it might possibly be a Protoglyptus species. Simone (2006) classified this taxon as a Rhinus species , without further explanation. Upon examination of the type material, the protoconch sculpture appears consisting of axial riblets, spaced 1-2 times the width of the riblets, with very fine spiral striation in between the riblets. This places this taxon in the genus Protoglyptus Pilsbry, 1897 .

Current systematic position: Bulimulidae , Protoglyptus heterogrammus (S. Moricand, 1836) (comb. n.).
