referred them to the genera Agnopterus, Coturniz, Cryptornis, Falco, 
Gypsornis, Laurillardia, Limosa, Palxgithalus, Palxocircus, Palzxortyz, 
Pelidna, Phalacrocorar, Rallus, and (?) Tringa. Of these the extinct 
genera are the first, which was probably distantly allied to the 
Flamingos; the third, believed to be a Hornpitt (A. Milne- 
Edwards, Ois. Foss. Fr. 11. p. 547); the fifth a Ralline form; the sixth 
now shewn to be allied to Hartlaubia of Madagascar ;1 the eighth 
(originally identified with Sita) probably connecting Parus (Tir- 
MOUSE) and Sylvia (WARBLER); and the ninth and tenth re- 
spectively referable to the Accipitres and the Gallinw. The 
equivalent beds of Hordwell in Hampshire have yielded remains 
of several birds,” including an Accipitrine, Actiornis, Agnopterus (?), 
Colymboides, Elornis (2), Geranopsis, Girus, Ibidopsis, of which the 
second being allied to the Cormorants, the fifth to the Cranes, 
and the last to the Ibises, are peculiar to these deposits. The 
third, fourth, and fifth, are mentioned below. Nothing can be 
said as to the affinities of the bone from the same beds described 
as Macrornis by Prof. Seeley. Gus (Palxogrus) also occurs in the 
Italian Eocene. The Marl beds of Aix in Provence, belonging to 
this epoch, have yielded fossil eggs and feathers, but as yet no 
bones of Birds; and to the same period must probably also be 
assigned the lacustrine calcareous deposits of Armissan, in 
Languedoc, whence M. Gervais recovered remains originally 
referred to Tetrao (GROUSE), but subsequently to a distinct though 
allied genus Yaoperdiz. The bird-bones of the Upper Eocene 
Phosphorites of Central France, although numerous, have as yet 
been only partially described. They include remains of Passeres, 
Picarix, and Accipitres, together with Palxortyz, the Stork-like 
Propelargus, and Avgialornis, the last being apparently allied to the 
Gulls, but with a shorter wing. From the Eocene of Wyoming 
Prof. Marsh (dm. Journ. Sci. ser. 3, iv. p. 256) has described five 
birds varying in size from a Flamingo to a Woodcock, all of which 
are referred to an extinct genus Alefornis, presumably allied to the 
Gruidx (CRANE). Remains referred to Bubo and Charadrius, as well 
as the extinct Uintornis, referred to the Picide (WOODPECKER) and 
Palxospiza, have likewise been obtained from the Eocene of the 
United States. Our list of birds of this epoch closes with Palxeu- 
dyptes, a giant PENGUIN from New Zealand described by Prof. 
Huxley (Q. Journ. Geol. Soc. xv. p. 670). 
The freshwater beds of Hempstead in the Isle of Wight, as 
well as those of Ronzon near Puy-en-Velay, form a transition from 
the greatest use in preparing the present summary. To Prof. Seeley also I have 
owed much assistance.—A. N.
