Amastra montivaga Cooke

Mountain-wandering Amastra Snail (Amastra montivaga)

The Mountain-wandering Amastra Snail was described in 1917; it was found on the Kalihi Ridge, which is a mountainous region on the island of O’ahu, Hawaiian Islands.

“A. montivaga is undoubtedly a dirivative [sic] of A. textilis. It differs from the latter species by its smaller size, thinner shell, more convex whorls (which are shouldered below), deeper sutures, etc.” [1]

The shells of this species reach sizes of 1,2 to 1,6 cm in height.
