It was the larger of two species of rail found on the island of Maui, Hawaii. Several specimens of this bird were found in early settlements. It was 1 foot 3 inches (38 cm) tall. Its beak was 0.75 inches (2 cm) inch long; its neck was 8.5 inches (22 cm) inches long. It was probably brown and grey and black like its recently extinct relatives the Hawaiian rail and Laysan rail. It was flightless due to its small wings that were on average less than 4 inches long.
It probably fed on the fruits, leaves, and flowers of trees that fell onto the ground, especially those of ‘ōhi‘a lehua (Metrosideros polymorpha), Mamane (Sophora chrysophylla), and Lobelia spp.
The cause of extinction is not well established, but it was likely hunted for meat, and its bones and feathers were used in old style art. It may have also have been predated by Polynesian rats that were introduced by early Polynesian settlers.
