Amastra morticina Hyatt & Pilsbry

Dead Amastra Snail (Amastra morticina 

This species was described in 1911, apparently based on subfossil specimens that had been collected from sandy deposits at the Kahului Bay at the northern coast of Maui, Hawaiian Islands.  

The species was already extinct at that date, it very likely disappeared shortly after the occupation of the island by the first Hawaiian settlers.  


The shells reach sizes of about 1 to 1,5 cm, those of the type specimens are dull reddish colored while others are whitish colored (see picture)
