{161}DISTRIBUTION.--This species is found throughout the whole of the
Peruvian Amazons, though not in very large numbers--indeed, it is said to
be rare. It has been recorded from Cashiboya on the Ucayali, and Santa Cruz
on the Huallaga. Mr. O. Thomas mentions his having examined twelve
specimens from the Copataza river, and one from Andoas in Ecuador. Of these
he says: "The Andoas specimen, which is a male, differs from the rest in
having the fur on the back of a dirty orange-grey colour, without
annulations, instead of being of a bright annulated black and white. One of
the others, a female, shows a tendency to this condition of the hair, which
is, therefore, probably a seasonal change, as the Andoan specimen was shot
in September, while the others were obtained between December and
February."
