There is a skull of a young male American Deer which was in 

 the Zoological Gardens, the skin of which has not been preserved.

 the rather slender face of the Virginian Deer ; but it has a much 

 larger, subtrianglar, suborbital pit, of the same form, but only 

 about two-thirds the size of the pit in the skull of the broad- 

 faced Long-tailed Deer. It indicates the existence of another 

 species, that may be characterized by the skull. Nasals : each
