Small Hawaii Crake (Zapornia sp.)  

This form is known from several subfossil remains that had been recovered from a site at Mauna Kea on the island of Hawai’i, Hawaiian Islands, at an elevation of 1450.  

The Small Hawaii Crake falls within the size range of the Hawaiian Crake (Zapornia sandwichensis (Gmelin)) and may in fact turn out to be identical with that species. [1]
