the one I figure in another connexion, that is, fig. 74 of pl. lv 
of my paper, ‘‘ Further Studies of Fossil Birds, with Descriptions of 
New and Extinct Species”: Amer. Mus. Nat. Hist. Bull., N.Y., 
vol. xxxii, art. xvi, p. 290, August 4, 1913.1 The bone there figured is 
of a left femur, while the one described in the present article is from 
the rzght pelvic limb; and in so far as I am able to judge from the 
cited fig. 74 the two bones are wonderfully alike, both in the matter 
of form and proportions. Unfortunately, the femur shown in fig. 74 
- is so firmly fixed in its flinty matrix that the popliteal area cannot 
be examined properly. To all appearances, however, the femoral 
condyles were of the same size and form; and had I had these two 
specimens together at the time the bone in fig. 74 was described, 
it is quite possible that, by the aid of the greater number of exposed 
characters in the specimen described in the present article, I would 
have referred them both to the same species, or at least to the same 
genus. In fact, the Miocene types of both the gallinaceous birds 
and the anserine ones may have had not a few osteological characters 
in common. 
For this extinct and probably largest anserine bird discovered in 
America up to the present time, I here propose the name of Palao- 
chenoides mioceanus,* gen. et sp. nov. 
In preparing this account I am indebted to Dr. O. P. Hay for 
various courtesies extended to me during the time the material was 
in my possession; to Dr. Earle Sloan, of Charleston, S.C., for 
information with respect to the discovery of the specimen and the 
formation to which it belongs; and to Mr. J. H. Riley, of the Division 
-of Birds of the U.S. National Museum, for assistance in selecting bird 
skeletons in the collection of that institution for comparison with the 
material in hand. 
EXPLANATION CF PLATE XV. 
Fie. 1.—Direct outer aspect of the distal part of the right femur of Pal@o- 
cheniides mioceanus (extinct). All the figures are natural size, and 
are reproductions of photographs of the specimen made by the 
author. 
,, 2.—The same bone on direct inner side view. Here the specimen is 
slightly tipped toward the observer in order to show the matrix 
filling the thin, hollow shaft. This tipping causes Fig. 2 to be 
somewhat shorter than the other figures. 
,, 3.—The same specimen viewed directly from in front.

1 IT am not responsible for the title given pl. lvii of that paper; and on the 
page cited I say that it appears to have been a gallinaceous fowl, but that the 
material does not admit of a scientific reference. 
2 Generic name = Gr. maAaids = ancient, + x7v, a goose, + oedys, having 
a resemblance to, or, in other words, having the general characters of, some of 
the very early ancestors of the anserine birds. Sp.=Gr. welwy = less, + Kaivds, 
recent: a subdivision of the Tertiary named by Lyell.
