Gayal

In his first description of 1804, Aylmer Bourke Lambert applied the binomial Bos frontalis to a domestic specimen probably from Chittagong. In 2003, the International Commission on Zoological Nomenclature has fixed the first available specific name based on a wild population that the name for this wild species is valid by virtue of its being antedated by a name based on a domestic form. Most authors have adopted the binomial Bos frontalis for the domestic species as valid for the taxon.
