36 FLORIDA GEOLOGICAL SURVEY-NINTH ANNUAL REPORT. 
CATHARTES AURA. STRATUM 2. 
(Plate I., Figs. 1, 2.) 
One of the most conspicuous bones in this part of the collection 
is the imperfect specimen of a left ulna of Cathartes aura; it is in 
two pieces (Plate I., Fig. 2), the bits of the shaft joining them hav¬ 
ing been lost. So far as it goes, the specimen is practically perfect, 
barring a slight chipping of the extremeties. It agrees in all partic¬ 
ulars with the ulna of the Turkey Buzzard as it occurs at the present 
clay; even the distances between the papillae for the ends of the sec¬ 
ondary feathers of the wing are the same in number, and occupy 
identically the same positions on the shaft. 
QUERQUEDULA FLORIDANA, sp. nov. 
(Plate I., Fig. 4. Plate II., Fig. 25. Compare with Fig. 3.) 
Pleistocene, Vero, Fla., Stratum 2. 
There is present in the collection the right humerus of a small 
anserine bird, closely related to our Teals of the genus Querquedula . 
Comparisons have been made with several species of that genus; 
but it differs in one way and another from all of them, while it 
agrees in general character. It appears to be most nearly like the 
humerus as we find it in Querquedula discors, but differs from it in 
being somewhat shorter throughout; that is, the extremities of the 
bone are relatively larger and the shaft stouter. This humerus 
belonged to a species of Querquedula now extinct, and I propose 
for it the name of Querquedula floridana, the type bone being the 
humerus here described and figured. Extreme length, 6.6 cms.; 
extreme width of head (to apex of radial crest), 1.6 cms. Sigmoid 
curve of the shaft rather more pronounced than in Q. discors. 
Distally, the tubercles somewhat chipped—otherwise quite, perfect. 
ARDEA ? (sp. ?) Stratum 3. 
(Plate I., Fig. 5.) 
No. 6774. Represented by the distal two-thirds of a bird’s left 
tarso-metatarsus, with the condyles considerably broken away, but 
the shaft perfect. This bone has been compared with the corre-
