Mouflon and being black on the shoulders. In Corsica this animal is named Mufro. Pallas, grouping goats and sheep together into a single genus "Aegoceros", distinguished the mouflon from the argali at species level in 1811 ("Ae. musimon" and "Ae. argali" respectively). In 1840 Blyth proposed that the Armenian and Cypriot sheep were also separate species, which he named "Ovis Gmelinii" (after "the younger Gmelin") and "O. Ophion" (from a name recorded by Pliny). Current taxonomy in some sources such as MSW and ITIS treats the mouflons and urials as subspecies of the domestic sheep, "Ovis aries" Linn. 1758. However ICZN
Wild horse cranial and metacarpal differences, indicates the presence of only two subspecies in postglacial times, the tarpan and Przewalski's horse. At present, the domesticated and wild horses are considered a single species, with the valid scientific name for the horse species being "Equus ferus." The wild tarpan subspecies is "E. f. ferus", Przewalski's horse is "E. f. przewalskii", and the domesticated horse is "E. f. caballus". The rules for the scientific naming of animal species are determined in the International Code of Zoological Nomenclature, which stipulates that the oldest available valid scientific name is used to name the species.
