CERVUS ARISTOTELIS, 1835-7. Cervus aristotelis, Cuv. Oss. foss. (ed. 4) torn. vi. p. 84. Range. British India, Ceylon, Burmah, Siam, Hainan (Swinh.).

I have seen several living specimens of this species, all of which in their much darker colour, more bushy tail, short slightly curved antlers, presented a tout ensemble very unlike the common Sambur. On the other hand, I have received skulls and antlers from Siam which are strikingly intermediate between typical specimens of Cervus aristotelis and C. equinus. It appears to me therefore probable that the existence of these intermediate forms may ultimately render it impossible to maintain the distinction of the species. 3. CERVUS SWINHOII. 1862.
