Birds of the British Upper Eocene

The fossil birds of the British Upper Eocene are re-examined, further species are described, and additional material referred to existing species. Seeley's Macrornis tanaupus appears to be non-avian. Of the nine species listed by Lydekker (1891), the supposed cormorant, Actiornis anglicus, and the supposed flamingo, Elornis anglicus, appear referable to a single species of ibis under the former name; and Ibidopsis is transferred to the rails. The total number of forms now recognized consists of a diver, a cormorant, two ibises, a flamingo (based on limb shafts and unnamed), a telmabatid, a duck, a probable cathartid vulture, a hawk, an osprey, a rail and four waders. Seven new genera and seven new species are named.
