If domesticated cattle and gayal are considered separate species, they are to be named Bos taurus and Bos frontalis; however, if they are considered part of the same species as their wild relatives, the common species are to be named Bos primigenius and Bos gaurus.
Se o boi e o gaial domésticos son considerados como especies separadas, nomearanse como Bos taurus e Bos frontalis; porén, se se consideran parte da misma especie que o seus parentes silvestres, as especies comúns deberán denominarse Bos primigenius e Bos gaurus.
