peculiar arrangement of the colours, and the equality of 
the spaces between each cluster of spots. The face, sides 
of the neck, and both sides of the legs, are thickly studded

strong. The whole animal had an appearance of activity 
and strength, which fully confirmed the accounts of its 
prowess collected by Humboldt.

Cat, with a light-bay body ; black ears ; a claviform tail, 
brownish-black at the tip. 
I had an opportunity of inspecting several skins of this 
animal, the property of Mr Edmondston, who had killed 
them in the interior of Demerary, None of them were
