Leptachatina antiqua Pease

Antique Leptachatina Snail (Leptachatina antiqua)  

The Antique Leptachatina Snail was described in 1870, it was already extinct at that date as the author mentions in the description.:  

The shell is subfossil, oblong subcylindrical, solid scarcely rimate, longitudinally faintly striate; whorls 7, flatly convex, narrowly margined at the suture; spire somewhat obtuse; aperture oblong oval; columella obliquely truncate; columellar fold obsolete. Length 9.0, diam. 3,5 mm.” [1]  


The species was apparently a inhabitant of lowland areas and thus disappeared directly after the arrival of the first Polynesian settlers.
