Frick’s Disc Snail (Endodonta fricki)

Frick’s Disc Snail was described in 1858, it was apparently distributed over the whole Wai’anae Mountains on the island of O’ahu, Hawaiian Islands, some of the specimens included in here, however, are probably geographical subspecies or even distinct species. 

The shells of this species reached sizes of about 0,26 to 0,38 cm in heigth. [1]


Frick’s Disc Snail is now, like most of its congeners, extinct. [2]
