It is in the swampy forests of South America that the Jaguar commits his destructive ravages, which are spread over nearly the whole of that continent from Paraguay almost to the Isthmus of Darien. It has frequently been said that he is also to be found in Mexico; but this appears to be a mistake, originating probably in Buffon’s having confounded the Jaguar with the Ocelot, describing and figuring the latter under the name of the former, and intermingling with his description many of the peculiar traits of the real Jaguar derived from the relations of travellers. On the other hand he has erroneously figured the latter animal under the name of the Panther; a mistake in which he has been followed by Pennant and others, and with which the writings of zoologists are more or less infected even up to the present day. What the Panther of the ancients actually was, or whether there exists any real difference between it and the Leopard, is a much disputed question, into which we have neither space nor inclination to enter: certain it is that it could not possibly have been the present animal, which has never been found out of the limits of America; and that Buffon himself had no idea, while he was figuring the latter, that the specimen before him was not a native of Africa or the East. The name of Jaguar is corruptedly derived from the Brazilian appellation of the animal, to which the Portuguese have given the name of Onça; another blunder, for the Ounce of the Old World is now universally allowed to be identical with the Leopard, and with the latter we have already shown that it is impossible that the American species can be conjoined.
