melanistic tendencies in this species have been discussed by Anderson (1960:64), who examined the specimen from Tzitzio.
Further, melanistic gray squirrels then, as now, were common in western Pennsylvania and exceedingly rare in eastern Pennsylvania.
A mixture of the melanistic with the albinistic type will of course give rise to parti-coloured cats.
Abnormal white-spotting dorsally occurs as does yellow and melanistic coat color.
melanistic red squirrels, Tamiasciurus hudsonicus, are everywhere rare and in any case appear as individuals and not populations.
Not uncommon, although rarer than black or melanistic forms, are reddish or chestnut varieties.
This is not strange because melanistic specimens could not be identified anyway.
One melanistic individual was taken one mile northeast of Whitehorse on July 11.
melanistic specimens are rarer still, and I have seen but one, which was caught in Lodi Township in 1875.
