There was one black jaguar-skin; melanism is much more common among jaguars than pumas, although once Miller saw a black puma that had been killed by Indians. The patterns of the jaguar-skins, and even more of the ocelot-skins, showed wide variation, no two being alike. The pumas were for the most part bright red, but some were reddish gray, there being much the same dichromatism that I found among their Colorado kinsfolk. The jaguarundis were dark brownish gray. All these animals, the spotted jaguars and ocelots, the monochrome black jaguars, red pumas, and dark-gray jaguarundis, were killed in the same locality, with the same environment.

The spotted patterns conferred no benefit as compared with
