Virginian deer is at all affected by emasculation.
With most or all of the highly-ornamented
species of Tragelaphus the males are darker
than the hornless females, and their crests of
hair are more fully developed. In the male of
that magnificent antelope, the Derbyan eland,
the body is redder, the whole neck much blacker,
and the white band which separates these
colours broader than in the female. In the Cape
eland, also, the male is slightly darker than the
female. (25. Dr. Gray, 'Cat. of Mamm. in Brit.

derbianus: see the text on Tragelaphus. For the
Cape eland (Oreas canna), see Andrew Smith,

also many of these Antelopes in the Zoological
Gardens.)
