Bulimus fontainii d'Orbigny, 1838 Figs 16H , L24ii

Bulimus fontainii d’Orbigny 1838 [1834-1847]: 273.

Bulimulus fontainii ; Breure and Borrero 2008: 10.

Type locality.

[Ecuador, Prov. Guayas] "environs de Guayaquil".

Label.

”Guayaquil”, label in d’Orbigny’s handwriting.

Dimensions.

"Longueur totale, 13 millimètres; largeur 6 millimètres”; figured specimen herein H 13.2, D 6.4, W 8.5.

Type material.

NHMUK 1854.12.4.165, lectotype ( d’Orbigny coll.).

Remarks.

d’Orbigny did not state on how many specimens his description was based. The single specimen found in his collection matches the dimensions given, and is here designated lectotype (design. n.). The weak axial sculpture of the protoconch makes us considering this taxon to belong to Naesiotus sensu Breure 1979, awaiting further studies of this group.

Current systematic position.

Bulimulidae , Naesiotus fontainii ( d’Orbigny, 1838) (comb. n.).
