 According to records in the Anthropological Institute and Museum , AMZ 6698 , the holotype , is from " Equatorial Africa " , and AMZ @-@ AS 1730 is from the " Cameroons " . According to mammalogist Ronald Nowak , these designations imply that the latter came either from modern Cameroon or far eastern Nigeria ( British Cameroons ) and the former from Cameroon or a neighboring state . In 1999 , Simon Bearder claimed , citing a personal communication by C. Wild , that Pseudopotto had been seen in the wild and in 2001 , ornithologist Christopher Bowden noted the occurrence of Pseudopotto on Mount Kupe in Cameroon , also citing C. Wild . However , the IUCN Red List notes that while sightings of the false potto at 820 to 940 m ( 2690 to 3080 ft ) on Mount Kupe had been reported , surveys had failed to confirm its occurrence there , though pottos , some with long tails , had been found . The false potto is not listed separately from the potto in the Red List , because the evidence that it is a distinct species is considered insufficient .
