Fusus scalarinus Lamarck, 1816

( Figure 20 )

1816 Fusus scalarinus Lamarck : 8, pl. 437, fig. 2

1822 Fusus scalarinus Lamarck : 133, sp. no. 36

1832 Fusus nifat (Lamarck) Deshayes : 161

1840a Kiener: pl. 23, fig. 1 and pl. 24, fig. 2

Type locality: not stated.

Material in MHNG, Lamarck collection (tentatively selected by G. Mermod from the Delessert collection): 2 specimens MHNG INVE 51739 (ex MHNG 1098/41) (figured herein, Fig. 20A – B ); 1098/41/1 : 46 mm; 1098/41/2 : 36.5 mm. No locality on the label.

Remarks: According to Rosalie de Lamarck, there was only one specimen in her father’s collection. Lamarck stated a size of 16 lignes et demie (= 37.2 mm). The two specimens in the Lamarck collection were chosen by Mermod from a series of many specimens labeled Pusionella nifat in the Delessert collection. In the handwritten card file that he made for the Lamarck collection, Mermod noted that among the specimens which were in the Delessert collection, one matches Lamarck’s 1816 figure and also matches the 1822 description fairly well. It further matches the size (about 37 mm) given by Lamarck in (1822). This would mean that the note applies to specimen 1098/41/2 (36.5 mm), but subsequently Mermod labeled only the larger specimen 1098/41/1 (46 mm) as “ type ”. He also added that the 2 specimens selected were placed with doubt in the Lamarck collection because neither of them matches Kiener’s figures.

Current taxonomic position: Pusionella nifat ( Bruguière, 1789) ; placed in synonymy with Pusionella nifat [ Turridae ], the type species of Pusionella Gray, 1847 , by Tryon (1881): 271. Locality is West Africa.
