Aletornis pernix, Marsh, Am. Jouni. Sci., iv, Oct., 1872, p. 256. — Coues, Key, 1872, 
p. 348. 
About half the size of the above, and from the same locality. Also in the Yale Museum. 
14. ALETORNIS VENUSTUS. 
Aletornis venustus, Marsh, Am. Journ. Sci., iv, Oct., 1872, p. 257. — Coues, Key, 1872, 
p. 348. 
A smaller species, about as large as a curlew (Numenius). From the same locality, and 
likewise in the Yale Museum. 
15. ALETORNIS GRACILIS. 
Aletornis gracilis^ Marsh, Am. Joum. Sci., iv, Oct., 1872, p. 258. — Coues, Key, 1872, 
p. 348. 
A bird about the size of a w^oodcock (JPhilohela minor). From the same formation and 
locality, and now preserved in the Museum of Yale College. 
16. ALETORNIS BELLUS. 
Aletornis Mm5, Marsh, Am. Journ. Sci., iv, Oct., 1872, p. 258. —Coues, Key, 1872, 
p. 349. 
A still smaller species, probably belonging to a different genus. From the same locality, 
and also in the Yale Museum. 
LAMELLIROSTRES (p. 677). 
17. CYGNUS PALOREGONUS. 
Cygnus paloregonus, Cope, Bull. U. S. Geol. Surv. Terr., iv, no. 2, May 3, 1878, p. 388. 
Represented by numerous bones, especially by four metatarsals, two of which are nearly 
perfect, indicating a species very near those now existing, but apparently distinct. From the 
Pliocene of Oregon. Remains in Prof. Cope's Collection. 
18. BERNICLA HYPSIBATES. 
Anser hypsihates, Cope, Bull. U. S. Geol. Surv. Terr., iv, no. 2, May 3, 1878, p. 387. 
Based upon a metatarsal bone lacking the hypotarsus, indicating a goose nearly related to 
Bernida canadensis, but probably larger or with longer legs. From the Pliocene of Oregon. 
Remains in Prof. Cope's Collection. 
STEGANOPODES (p. 718). 
19. SULA LOXOSTYLA. 
Sula loxostyla, Cope, Trans. Araer. Philos. Soc, xiv, Dec, 1870, p. 23G. — Coues, Key, 
1872, p. 349. 
A gannet, not so large as the common living species (S. hassana), from the Miocene of 
North Carolina. The remains are preserved in Professor Cope's Collection. 
20. PHALACROCORAX IDAHENSIS. 
Graculus idahensis, Marsh, Am. Journ. Sci., xlix, Mar., 1870, p. 216. — Coues, Key, 
1872, p. 349. 
A typical cormorant, rather smaller than P. carbo. From the Pliocene of Idaho. Most 
of the known remains are deposited in the Yale Museum. 
21. PHALACROCORAX 3IACROPUS, 
Graculus macropus, 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 Phalacrocorax 
dilophus, and agreeing closely in size with Ph. idahensis.
