Oppian knew the panther and ounce, and was the first who observed there were two species of the former, the one large and the other small. Though alike in the form of their bodies and the disposition of the spots, yet they differed in the length of their tails, which in the small species was longer than in the large ones. The Arabians have named the large panther Nemer, and the small one Phet or Phed; which last seems to be a corruption of Faadh, the present name of this animal in Barbary. "The Faadh," says Dr. Shaw, in his Travels, "resembles the leopard, (he should have expressed it panther) in having similar spots, in other respects they however differ, for the skin of the faadh is more dark and coarse, and its disposition is also less fierce." Besides we learn from a passage of Albert, commented on by Gesner, that the phet, or phed of the Arabs, is called in the Italian, and some other European languages Leuaza, or Lonza. It is beyond a doubt then, that the little panther of Oppian, the phet or phed of the Arabians, the faadh of Barbary, and the onza, or ounce of the Europeans, is the same animal; and probably also is the Pard or Pardus of the ancients, and the Panthera of Pliny; since he mentions its hair is white, whereas, as we have observed, that of the great Panther is yellow. It is, besides, highly probable that the little panther was simply called pard or pardus, and that, in process of time, the large panther obtained the name of leopard, or leopardus, from a notion that it was a mongrel species, which had aggrandized itself by an intermixture with that of the lion. As this could only be an unfounded prejudice, I have preferred the primitive name of panther to the modern compound one of leopard, which last I have applied to another animal that has hitherto been mentioned by equivocal names only. The ounce therefore differs from the panther, in being smaller, having a longer tail, also longer hair, of a whitish grey colour; while the leopard differs from them both, by having a coat of a brilliant yellow, more or less deep, and by the smallness of his spots, which are generally disposed in groups, as if each were formed by three or four united. Pliny, and several after him, have said, that the coat of the female panther was whiter than that of the male. This may be true of the ounce, but no such difference have we ever observed in the panthers belonging to the menagerie of Versailles, which were designed from life; and if there be any difference between the colour of the male and female it can be neither very permanent nor sensible; in some of the skins we have, indeed, perceived different shades, but which we rather ascribed to the difference of age or climate than of sex.
