Hawkins' Rail was a large flightless rail from the Chatham Islands east of New Zealand, known to Europeans only from subfossil bones. Based on the level of detail in the traditions of the native Moriori the bird probably survived into the 19th Century, although it was not recorded in life by Europeans.

This specimen has a collection date of 27 March 1919, so it is probably a single skeleton rather than a composite from several birds.
