The present investigation was undertaken with the object of
inquiring into the significance of the colour variations of the Tasmanian
Brush Opossum, Trichosurus vulpecula fuliginosus Ogilby. The main investigation has not proceeded very far, and it is clear

several years of experimental work. In the present paper the
results of the preliminary inquiry are put on record, since they
throw light upon the distribution and relative abundance of the
two principal colour groups of T. v. fuliginosus
