forms belong to the Gallinaceous group, as represented by quails 

 (Colinus), grouse {Tympanuchus), pheasants (Phasianus) and tur- 

 keys (Meleagris); and, while there is but one new falcon represented 

 {Falco falconella) , there is considerable evidence that both the diurnal 

 and nocturnal raptorial birds were more or less abundant. The re- 

 markable feature is that both these and the fowls were so much like 

 or actually typical representatives of existing genera. 



For the rest, the list is made up of waders and water birds belonging 

 to the genera shown; and a number of these — indeed, nearly all of 

 these — likewise represent existing genera, and probably would not 

 have been at all out of place in the North American avifauna of the 

 present day. 



EXPLANATION OF PLATES 



[All the Figures on the Plates are reproductions of photographs made direct from 

 the specimens they represent by the author.] 



PLATE I 

 [Figures 1-6 on this Plate are reduced rather more than one-sixth.] 



Fig. I. Inner aspect of the distal portion of the right tarso-metatarsus of 

 Baptornis advenus Marsh. 



Fig. 2. Outer aspect of the proximal portion of the right (?) tarso-metatarsus 

 of Baptornis advenus JMarsh. Had this piece alone been discovered, it presents 

 no character, as yet, by which it might, with certainty, be determined as to whether 

 it belonged to the right or left pelvic limb. It came from a subadult individual. 



Fig. 3. Anterior aspect of the distal portion of the right tarso-metatarsus of 

 Baptornis advenus Marsh. 



Fig. 4. Posterior aspect of the distal portion of the right tarso-metatarsus of 

 Baptornis advenus Marsh. Figs. 1-4 are all the same specimen. 



Fig. 5. Anterior aspect of the proximal portion of the right tarso-metatarsus of 

 Baptornis advenus Marsh. See note under Fig. 2. 



Fig. 6. Posterior aspect of the proximal portion of the light tarso-metatarsus 

 of Baptornis advenus Marsh. See note under Fig. 2. Figs. 2, 5 and 6 are all 

 of the same specimen. 



Figs. 7-9. Dorsal, plantar, and outer aspect, respectively, of the first or basal 

 phalanx of the outer pedal digit of Barornis regens Marsh. Slightly smaller than 

 natural size. In the opinion of the present writer, this bone came from the skeleton 

 of the foot of a specimen of Diatryma. (See Plate V, Fig. 32.)
