1. PAL^OSPIZA BELLA. 
FalcBOspiza hella, Allen, Bull. U. S. Geol. Surv. Terr., iv., no. 2, May 3, 1878, pp. 443- 
445, pi. i, figg. 1, 2. — Am. Journ. Sci., xv. May, 1878, p. 381. — Amer. Nat., xv. Mar., 
1881, p. 253. 
Based upon some beautifully preserved remains, from the insect-bearing shales of Floris- 
sant, Colorado, now deposited in the Museum of the Boston Society of Natural History. They 
consist of the greater part of the skeleton, including all the bones of the wings and legs ex- 
cepting the femurs, but unfortunately lacking the bill. The impression of the feathers of the 
wings and tail are remarkably distinct, showing not only the general shape of these parts, but 
the shafts and barbs of the feathers themselves. The bones are all in situ, ^' and indicate be- 
yond question a high ornithic type, probably referable to the oscine division of the Passeres. 
The lack of the bill renders it impossible to assign the species to any particular family, but the 
fossil on the whole gives the impression of Fringilline afl&nities." The approximate length of 
the specimen is seven inches.

2. UINTORNIS LUCARIS. 
Uintornis lucaris, Marsh, Am. Journ. Sci., iv, Oct., 1872, p. 259. — Coues, Key, 1872, 
p. 347. 
This bird was about as large as a robin, and apparently related to the woodpeckers. The 
only known remains are from the Lower Tertiary formation of Wyoming Territory. They are 
preserved in the Museum of Yale College. 
RAPTORBS (p. 496). 
3. AQUILA DAN AN A. 
Aquila danana, Marsh, Am. Journ. Sci., ii, Aug., 1871, p. 125. — Coues, Key, 1872, 
p. 347. 
This species was nearly as large as the golden eagle (A. clirysaetus). The only known 
remains were found in the Pliocene of Nebraska, and are preserved in the Yale Museum. 
4. BUBO LEPTOSTEUS. 
Buho leptosteus, Marsh, Am. Journ. Sci., ii, Aug., 1871, p- 126. — Coues, Key, 1872, 
p. 347. 
A species about two-thirds as large as the great horned owl (B. virginianus) . The re- 
mains were discovered in the Lower Tertiary beds of Wyoming, and are now in the Yale 
Museum.

From the Pliocene of New Mexico; remains found in the sands north of Pojuaque, repre- 
senting a rapacious bird in size intermediate between the golden eagle and the turkey vulture;
