Illustration of the white swamphen (Porphyrio albus, here as Notornis alba), also known as the Lord Howe swamphen, Lord Howe gallinule or white gallinule, an extinct species of rail which lived on Lord Howe Island, east of Australia. It was first encountered when the crews of British ships visited the island between 1788 and 1790, and all contemporary accounts and illustrations were produced during this time. Today, two skins exist. Illustration by John Gerrard Keulemans from 'Extinct Birds: an attempt to unite in one volume a short account of those birds which have become extinct in historical times: that is, within the last six or seven hundred years: to which are added a few which still exist, but are on the verge of extinction' by Baron, Lionel Walter Rothschild, published in 1907.
