The skin was bought by Mr. Prichard from Indians in the region mentioned, so that neither flesh-measurements nor skull were obtained.

The second skin is that of a young male, killed on the Senguerr River, in March 1897, by one of the collectors from the La Plata Museum, by whom it was presented to the British Museum. Owing to its youth, its peculiarities had not been previously noticed.

F. c. Pearsoni is distinguished from F. c. puma not only by its very different general colour, but also by its shorter tail, light-coloured ear-backs, and the absence of the dark markings round the digital pads.
