From the Pliocene of Oregon, in which it appears to have been numerous ; represented by 

 various bones, those upon which the species is based being three nearly perfect metatarsals in 

 the collection of Professor Cope, indicating a bird somewhat larger than the living Phalacro- 

 corax dilophus, and agreeing closely in size with Ph. idahensis.

Gastornis giganteus Coues, Key, 2d ed. 1884, p. 825. 



From the Eocene of New Mexico, of the Wahsatch epoch; based upon a tar so -metatarsal 

 bone lacking a part of the shaft and the external condyle. The species was of great size, the 

 proximal end of the bone being nearly twice the diameter of that of the Ostrich. " Its discovery 

 introduced this group of Birds [Batitce] to the known faunse of North America, and demon- 

 strates that this continent has not been destitute of the gigantic forms of birds now confined to 

 the southern hemisphere fixunte " (Cope). The proximal end of the bone is described as re-
