SYSTEMATIC SYNOPSIS OF FOSSIL BIBBS. 823 



referred at first to 'the genus Cathartes, afterward provisionally to the genus Vuliwr. As the 

 description and figures clearly uidicate 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, Palesoborus, based upon the characters 

 given by the describer.

6. MELEAGRIS ANTIQUUS. 



Mekagris antiguus, Marsh, Am Jouru. Sci., ii, Aug., 1871, p. 136. — COUBS, Key, 

 1872, p. 347. 



This species was nearly as large as the wild turkey (M. gallipavo). The remains repre- 

 senting it were found in the Miocene of Colorado, and are preserved in the Yale Museum. 



7. MELEAGRIS ALTUS. 



Mehagris alius, Marsh, Proc. Phila. Acad., Mar., 1870, p. 11. — Amer. Nat., iv, July, 

 1870, p. 317. — Am. Jouru. Sci., iv, Oct., 1872, p. 260. — Coues, Key, 1872, p. 348. 



Mekagris swpeirbus, Cope, Syn. Ext. Batrach., etc., p. 239. 



" Represented by portions of three skeletons, of diflferent 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.'' Prom the 

 Post-pliocene of New Jersey. The remains are mostly in the Museum of Yale CoUege. 



8. MELEAGRIS CELER. 



Mekagris ceUr, Marsh, Am. Journ. Sci., Oct., 1872, p. 261. — Ootjes, 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. Marsh, Am. Journ. Sci., xlix, March, 1870, p. 214. — CoxiBS, Key, 1872, 

 p. 348. 



A species about as large as the sandhill crane {G. canadensis). From the Pliocene of 

 Nebraska. Remains preserved in the Museum of the Philadelphia Academy. 



11. GRUS PROAVUS. 



Grus proavus, Marsh, Am. Journ. Sci., iv, Oct., 1872, p. 261. — CouBS, 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 inthe Yale Museum.

Aktornis noUUs, Marsh, Am. Journ. Sci., iv, Oct., 1872, p. 256. — CouES, Key, 1873, 

 p. 348. 



Nearly as large as the preceding species. Found in the Eocene deposits of Wyoming, 

 and now in the Museum of Yale College.
