There is an animal in Guiana very similar to the common marten, its
principal difference consists in its being some trifle larger, and in
having its hair sprinkled with black and white, a shorter tail, and
spotted on the head; there is also a material difference in the toes,
those of the latter animal bearing a much greater resemblance to that
of a rat or squirrel than to the toes of a marten.
