130 THE CONDOR Vol. XXIII 
single fragment of a humerus represents the total previously known bird 
remains from California deposits older than Pleistocene (Lucas, 1901). 
Study of the enormous mass of bird material assembled at the University 
of California and at the Los Angeles Museum of History, Science and Art has 
been productive of most interesting results. The following is a synopsis of 
this work, only part of which has been made public. 
Apologies are offered for one synonym imposed upon the literature of 
ornithology. Pleistogyps rex (Miller, 1910), based on a tarso-metatarsus, 
must give way to Teratornis merriami (Miller, 1909), previously established > 
upon a skull and pectoral arch. Repeated occurrence of the two in the same 
section of the excavations forces the conclusion that the great bird known from 
the skull and pectoral parts was mounted upon the relatively frail posterior 
limbs aseribed to Pleistogyps rex. The latter genus and species is herehy 
officially cremated. Two members of the family of old vultures, heretofore 
unknown in the western hemisphere, have been described (Miller, 1916b). The 
species Pavo californicus Milier has been assigned to a new genus, Parapavo 
(Miller, 1916a), intermediate between the old world Pave and the new world 
Agriocharis of Yucatan. The anomalous walking eagle, Morphnus daggett, has 
been described (Miller, 1915) as analogous and not homologous with Serpentu- 
rius of South Africa. 
Gavia, Ajaia, Plegadis, Geococcyx, and two species of the Columbidae, 
listed as lipotypes in 1912, have been added to the Pleistocene fauna. The 
meager remains first assigned to Polyborus tharus are considered, alter study 
of more abundant material, to belong to the species P. cheriway. Botauwrus 
lentiginosus, Grus americana, Accipiter coopert, and Falco columbarius have 
been added to the California list of Pleistocene species. The species Agelaius 
gubernator, Xanthocephalus xanthocephalus, Euwphagus cyanocephalus, and 
Otocoris alpestris are considered best dropped from the rolls at present. Al-_ 
though the Pleistocene remains studied are not distinguishable to the writer’s 
eye from the four above-mentioned local birds, it is assuming too much on his 
part to assert the identity thereof. The identity is not considered proven. 
More complete material representing the Recent faleons makes it seem advis- 
able to drop Falco peregrinus and add F. mexicanus in its stead. 
Eliminating tentative assignments from the lst, there are now known 
some sixty-four species of birds from Pleistocene horizons, and one from the 
Miocene, of California. The state of Oregon exceeds this record by some five 
or Six species.
