Mr. Titian Peale describes the hoofs of his Mule Deer as ditfei-ent 

 from those of the Black-tailed Deer ; but Dr. Spencer Baird says that 

 the hoofs of both the species he describes were alike and slender ; so 

 that perhaps Mr. Peale's animal may be a third species of the genus, 

 characterized by the hoofs, like the Elk and the Wapiti. 



Dr. Spencer Baird refers Cervus punctulatus (Gray, P. Z. S. 1850, 

 t. 2S) to this species with doubt ; but he states he has not been able' 

 to refer to the figure. Most probably, as it came from California, it 

 does belong to this species ; but, unfortunately, the skin was not 

 preserved when it died.
