ventulus Férussac, 1825 , Helix

( Fig. 5E View FIG )

Helix ventulus Férussac in Quoy & Gaimard, 1825: 481.

Helix (Cochlogena) ventulus – Férussac 1821a: 60; 1821b: 56 [nomen nudum].

CURRENT TAXONOMIC STATUS. — Leptachatininae, Leptachatina (Leptachatina) . Valid species.

TYPE MATERIAL. — Lectotype (here designated) MNHN IM-2000- 30848.

TYPE LOCALITY. — “l’île Guam ” (in text; error) (“ Sandwich Islands ”; on label) .

REMARKS

Both Férusssac (1821a: 60, 1821b: 56) and Férussac in Quoy & Gaimard (1825: 481) gave the locality as Guam, whereas the labels (including one with black borders typical of the Férussac collection) correctly indicate the Sandwich (i.e. Hawaiian) Islands, as the genus Leptachatina (and the entire family Amastridae ) is endemic to the Hawaiian Islands. This Férussac collection label also indicates that the shell was from Gaudichaud, as stated by Férussac (1821a: 60, 1821b: 56), confirming that it was obtained during the Freycinet voyage. Another label says “type” and “collection Férussac”, and another “Coll. Férussac 1837”. The shell height (13 mm) matches that given by Férussac in Quoy & Gaimard (“cinq lignes et demie”, i.e. 12.4 mm) but its width (6.7 mm) is greater than Férussac’s (“deux et demie”, i.e. 5.6 mm), although within a reasonable margin of error. We here designate this specimen as the lectotype. The species was not treated by Deshayes (1851).
