Amastra davisiana Cooke

Konahuanui Amastra Snail (Amastra davisiana)  

This species was described in 1901.  

The species was apparently endemic to the summit of the Pu’u Konahuanui, a mountain in the Ko’olau Range on the island of O’ahu, Hawaiian Islands.  

The shells reached sizes of about 1,44 to 1,65 cm.  

The Konahuanui Amastra Snail is now considered extinct.
