FIGURE 44 
A relatively small cat, smaller than a modern puma but distinctly 
larger than a lynx, is represented by portions of a skeleton, No. 16618. 
These were found beneath the scapula of a mastodon and in close prox- 
imity to the skull of Canis edwardi. 
The material includes several vertebrae, 
a few foot bones and certain of the limb 
bones, among which are a complete 
humerus (fig. 44), femur and tibia. 
In the Pleistocene record there ap- 
pears to be a dearth of cat material 
representing a form comparable to the 
smaller Curtis ranch type. The limb 
elements, however, compare favorably 
with those of Felis lacustris > from the 
earlier Hagerman lake beds of Idaho. 
The limb bones of the Hagerman skele- 
ton, found subsequent to the description 
of F’. lacustris, are for the most part in- 
complete, but the astragalus, the proxi- 
mal and distal portions of the humerus 
and tibia, and the distal portion of the 
femur are nearly identical in propor- 
tions to those in the Curtis ranch cat. 
It should be noted, however, that the
