Fig. 54

Bulimus mexicanus Lamarck, 1822: 123 . – Delessert, 1841: pl. 27 figs 9a-b. – Chenu, 1850 [1842-1854]: pl. 8 figs 1a-b. – Mermod, 1951: 730, fig. 80.

Type locality: “le Mexique ”, see remarks.

Label: No locality given.

Dimensions: “Longueur, 14 lignes [H = 31.1 mm]”; figured specimen herein H 30.9, D 17.2, W 6.2.

Type material: MHNG-INVE-51166, two syntypes (Lamarck coll.).

Remarks: Lamarck used material collected by Humboldt and Bonpland, but did not state how many specimens he examined. Mermod (1951) confirmed that the protoconch sculpture is characteristic for Drymaeus and repeated the opinion of earlier authors (e.g. Pilsbry, 1898 [1897-1898]: 292) that is taxon is in fact a species from northern Peru. The material has no taxon label in Lamarck’s hand, but the type status of the material is not disputed herein.

Current systematic position: Bulimulidae, Drymaeus (Drymaeus) mexicanus (Lamarck, 1822) .
