17. CYGNUS PALOREGONUS.

Eepresented by numerous bones, especially by four metatarsals, two of which are nearly

 Pliocene <if Oregon. Remains in Prof. Cope's Collection. 



18. BERNICLA HYPSIBATES. 



Anser Imjiisibates, Cope, Bull. U. S. G-eol. Surv. Terr., iv, no. 2, May 3, 1878, p. 387. 



Based upon a metatarsal bone lacking the hypotarsus, indicating a goose nearly related to 

 Bemicla canadensis, but probably larger or with longer legs. From the Pliocene of Oregon. 

 Remains in Prof. Cope's Collection. 



STEG-ANOPODES (p. 718). 



19. SULA LOXOSTYLA.

 1872, p. 349. 



A gannet, not so large as the common living species {S. hassanci), from the Miocene of 

 North Carolina. The remains are preserved in Professor Cope's Collection. 



20. PHALACROCORAX IDAHENSIS. 



Grticiilns idahensis, Marsh, Am. Journ. Sci., xlix, Mar., 1870, p. 21G. — Coues, Key,

A typical c<irmorant, rather smaller than P. carho. From the Pliocene of Idaho. Most 

 of the known remains arc deposited in the Yale Museum. 



21. PHALACROCORAX MACROPUS. 



Ontculus macrojnis, Cope, Bull. U. S. Geol. Surv. Terr., iv, no. 2, May 3, 1878, p. 386. 



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 Prof. Cope, indicating a bird somewhat larger than the living PJialacrocorax 

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