Onza! The Hunt for a Legendary Cat (edition 1995)

Amazon.com Product Description (ISBN 0944383289, Paperback)

For centuries, Indian myths and Hispanic legends have told of a mysterious large wildcat, the Onza, said to inhabit the mountains and jungles of Mexico's Sierra Madre Occidental. Not a jaguar, not a mountain lion, the Onza is considered more elusive and ferocious than either. In the 20th century a variety of American hunters, writers, cryptozoologists and roustabouts have sought to unravel the mystery of the Onza. These men, including J. Frank Dobie, the Lee brothers, Robert Marshall, and Russell Annabel, have ranged the Mexican wilds to give the truth or lie to the Onza legend. This book slays the myths, celebrates the lore, and tells their stories of adventure.
