in the recent deer; also, P, is noticeably large and the talonid portion 
relatively broad. The portions of antlers, though in part robust, are 
comparable structurally to those in modern individuals of either 
Odocoileus or Eucervus, but not complete enough to attempt a closer 
comparison to one or the other of these subgroups. 
The Curtis ranch deer is probably not greatly different in size 
from that which Hay ** described as Sangamona fugitiva, although 
there are no upper teeth in the Curtis ranch collection with which 
comparisons may be made. The lower teeth in the Curtis ranch 
jaws appear larger than in the illustrations of the forms which Frick 
(1937, pp. 191-202, fig. 20) described as Odocoileus sheridanus from 
Nebraska, or the earlier Procoileus edensis from Eden, Calif. The 
character of P, as illustrated for the Eden form is noticeably different 
than that in the Curtis ranch material.
