Cookeconcha paucilamellata (Ancey)

Hamakua Cookeconcha Snail (Cookeconcha paucilamellata)  

The Hamakua Cookeconcha Snail was described in 1904, originally as a ‘variety’ of another species, the Mountain Cookeconcha Snail (Cookeconcha hystricella (Pfeiffer)) from the island of O’ahu, one of probably only three species of this genus still surviving.

However, this species originates from the biggest of the Hawaiian Islands, Hawai’i itself, were it apparently inhabited the forest floor of the rainforest at the slopes of Mauna Kea. [1]

Cookeconcha lanaiensis (Sykes)

Lanai Cookeconcha Snail (Cookeconcha lanaiensis)  

The Lanai Cookeconcha Snail was, as its name implies, endemic to the island of Lana’i, Hawaiian Islands, it was described in 1896. [1]

This species is also considered to have occurred on the islands of Hawai’i and Kaua’i (the specimen depicted below is supposed to be from that island), however, the specimens from these islands should definetely be reinvestigated.
