SYSTEMATIC SYNOPSIS OF FOSSIL BIRDS. 823 
referred at first to the genus Cathartes, afterward provisionally to the genus Vultwr. As the 
description and figures clearly indicate a bird generically distinct from Cathartes, and as the 
improbability of the occurrence of a true Vultwr in North America is extreme, it is suggested 
that this species be made the type of a new genus, Pal@oborus, based upon the characters 
given by the describer.

MELEAGRIS ANTIQUUS. 
Meleagris antiquus, MARSH, Am. Journ. Sci., ii, Aug., 1871, p. 126.—Cougs, Key, 
1872, p. 347. 
This species was nearly as large as the wild turkey (MZ. gallipavo). ‘The remains repre- 
senting it were found in the Miocene of Colorado, and are preserved in the Yale Museum. 
MELEAGRIS ALTUS. 
Meleagris altus, MARSH, Proc. Phila. Acad., Mar., 1870, p. 11.— Amer. Nat., iv, July, 
1870, p. 317. — Am. Journ. Sci., iv, Oct., 1872, p. 260.— Cougs, Key, 1872, p. 348. 
Meleagris superbus, Copr, Syn. Ext. Batrach., ete., p. 239. 
‘‘ Represented by portions of three skeletons, of different ages, which belonged to birds 
about the size of the wild turkey, although proportionally much taller. The tibiae and tarso- 
metatarsal bones were, in fact, so elongated as to resemble those of wading birds.” From the 
Post-pliocene of New Jersey. The remains are mostly in the Museum of Yale College. 
MELEAGRIS CELER. 
Meleagris celer, Marsu, Am. Journ. Sci., Oct., 1872, p. 261. — Cours, Key, 1872, p. 348. 
A species much smaller than the foregoing, but with legs of slender proportions. Also 
from the Post-pliocene of New Jersey, and preserved in the Yale Museum.

Grus haydeni, MArsu, Am. Journ. Sci., xlix, March, 1870, p. 214.— Cours, Key, 1872, 
p. 348.

Nebraska. Remains preserved in the Museum of the Philadelphia Academy. 
GRUS PROAVUS. 
Grus proavus, MARSH, Am. Journ. Sci., iv, Oct., 1872, p. 261.— Cougs, Key, 1872, 
p- 348. 
This species was nearly as large as a sandhill crane. The remains representing it were 
found in the Post-pliocene of New Jersey, and are now in the Yale Museum.

Nearly as large as the preceding species. Found in the Eocene deposits of Wyoming, 
and now in the Museum of Yale College.
