Description

The genus Samoana was defined by American malacologist Henry Augustus Pilsbry in Manual of Conchology in 1909: ^[1]

The shell is very openly umbilicate, dextral or sinistral, with flatly reflexed lip and no teeth. Type P. canalis. Samoan Is., species 53 to 58.

In 1909, Pilsbry assigned six species to the genus Samoana. ^[1]
