 For example, John Edward Gray published the name "Antilocapra anteflexa" in 1855 for a species of pronghorn, based on a pair of horns.However, it is now commonly accepted that his specimen was an unusual individual of the species "Antilocapra americana" published by George Ord in 1815.Ord's name thus takes precedence, with "Antilocapra anteflexa" being a junior subjective synonym.
