50 E. Hitchcock on Fossil Footmarks of the Connecticut Valley. 
The protuberances on the foot of the turkey, both wild and — 
tame, correspond neither with the phalanges nor the articula- — 
tions, but are more numerous than either. The same is true — 
of the domestic hen. There is a general resemblance, however, — 
in this respect, between different individuals of these genera, 
tanus lentiginosus, the protuberances seem to cor — 
respond with the articulations, or joints. : 
n the Coot, the wings along the toes expand most in the mid — 
dle of the phalanges. 
In the Crow, the correspondence seems to be essentially with — 
the articulations, judging from some tracks of this bird on clay — 
in the cabinet. But the Struthionidse have feet more nearly — 
resembling the tracks under consideration. And in the hea — 
Americana or South American Ostrich, although these protube _ 
rances are tolerably distinct on the middle toe, yet the inner and — 
oes do not show them. A large heel shows itself behind — 
the middle toe. 
(Casts of the feet of the above bird were exhibited to the — 
Academy). 
These few examples show that there is a great diversity among — 
living birds in the matter under consideration. Sometimes the | 
tuberances correspond with the articulations, sometimes to the — 
halanges, and sometimes to neither. But I have never found — 
eet that would make such distinct and marked tracks, and with — 
always the same number of rounded impressions, as did the — 
thick toed Lithichnozoa; and I am still inclined to believe that |
