Moricand, 1836 Figs 40-41 Helix ( Helicigona ) pileiformis S. Moricand, 1836: 420 , pl. 2 fig. 2. Type locality: [ Brazil , Bahia ] “ Illheos ”. Label: “Illheos”, in Moricand’s handwriting. Dimensions: Not given; figured specimen herein H 19.5, D 12.8, W 7.1 . Type material: MHNG-INVE-64567 , four syntypes (ex Blanchet, Moricand coll.). Remarks: Moricand wrote: “Cette espèce, que je crois fort rare, puisque je n’en ai reçu qu’un seul individu”, suggesting that the original series was only one shell; Moricand did not mention the dimensions of his specimen. The present four specimens are accompanied by a label that confirms the material originating from Blanchet and locality Illheos. Therefore it is likely that either the original specimen was mixed with three specimens later received from Blanchet, or the holotype was lost and all specimens were subsequently sent by Blanchet. As this cannot be determined ex post, and the source and locality of the material are not disputed herein, these specimens are now considered as syntypes . The current systematic position follows Simone (2006) . Current systematic position: Bulimulidae , Pseudoxychona pileiformis (S. Moricand, 1834 ) .
