still inhabiting the region; thus their importance is limited to 

 the evidence they furnish of the division of a genus into several 

 coordinate species. 



In 1892, Shufeldt 2 published the results of an extended study 

 of the Cope and the Condon collections of birds from this same 

 region. In this very thorough discussion there are fifty species 

 enumerated, fourteen of which are described as new. The entire 

 number, with the exception of the gallinaceous Paleotetrix gilli, 

 are assigned to existing genera. Phoenicopterus is the only 

 existing genus recorded which is foreign to the region at present. 



In 1894, Cope 3 described a single species, Cyphornis magnus, 

 from a formation in Vancouver, British Columbia, which he 

 placed with some reservation in the Eocene, but which was later 

 considered by others to be Oligocene. The species is considered 

 as pelecanid in its affinities but generically distinct from any 

 form now living. 



Lucas, in 1901, 4 described a new genus and species of diver, 

 Mancalla calif orniensis, from a formation at Los Angeles, Cali- 

 fornia. From the associated invertebrate fauna, this species is 

 considered by Dall to be of upper Miocene or lower Pliocene age. 



As a result of the preliminary study put upon the University 

 of California collections by the present writer, there have ap- 

 peared a series of short papers dealing with a number of species 

 from Fossil Lake, Oregon, and from the~~caverns and the asphalt 

 beds of California. While these papers record one unique form, 

 Teratornis, of unusual interest, the main value of the contribu- 

 tions, like that of Shufeldt 's, lies in the light shed upon the 

 former distribution of families of birds still living. 5
