Cervus porcinus was the
scientific name used by
Eberhard August Wilhelm von Zimmermann in 1777 and 1780, based on an earlier description of Indian hog deer brought to England from India. It was placed in the genus
Axis by
William Jardine in 1835 and by
Brian Houghton Hodgson in 1847. In 2004, it was proposed to be placed in the genus
Hyelaphus. The proposal has not been accepted, with most authors keeping it under
Axis. A subspecies,
A. p. annamiticus, was once considered its own species, but is now generally considered the same species as
A. porcinus. ==Description==
