British Fossil Birds. 395 



the upper end. An ulna from the underlying Coralline Crag 

 preserved in the Museum of Practical Geology appears to 

 belong to the same species. Seeing that no Albatross is now 

 found anywhere near the British Isles, it is probable that 

 the bones from the Crag indicate a distinct species, for which 

 the name of D. anglica has been suggested by the writer. 



Fygopodes. —According to Prof. W. H. Flower, a humerus 

 from the Norwich Crag preserved in the Museum at Norwich 

 belongs to the Guillemot {Vria troile), colonies of which 

 bird existed up to about the middle of this century on the 

 neighbouring cliflFs of Cromer and Hunstanton. 



III. Birds of the Upper Eocene (Oligocene). 



Before noticing the birds from the Upper Eocene beds of 

 Hordwell, Hampshire, it should be observed that an imper- 

 fect coracoid of a large bird from the Lower Miocene beds 

 of Hempstead, in the same county, preserved in the Wood- 

 wardian Museum at Cambridge, has been made the type of 

 the genus Ptenornis. The very slight description which has 

 been given of this specimen, and the absence of a figure, ren- 

 der it, however, impossible to come to any conclusion as to 

 its affinities. With one exception, all the bird-remains from 

 Hordwell have been referred to extinct genera. 



Accipitres. — Evidence of the existence of an Accipitrine 

 bird, but little smaller than the Golden Eagle, is afforded by 

 two terminal phalanges of the feet from the Hordwell beds 

 preserved in the British Museum. Possibly these specimens 

 may prove to belong to an Accipitrine from the correspond- 

 ing horizon of the Paris basin described by M. Milne-Edwards 

 as Pal<£ohierax gervaisi. 



Steganopodes, — The ulna of a Cormorant is distinguished 

 from that of all other birds by the crotchet-like process pro- 

 jecting outwards and downwards from the surface for the 

 radial condyle of the humerus. The proximal end of an ulna 

 somewhat smaller than that of the Cormorant, preserved in 

 the British Museum, has a somewhat similar process, and 

 thus appears to indicate the occurrence in the Hordwell beds 

 of a Cormorant-like bird, for which the name Actiornis 

 anglicus has been suggested by the writer.
