[3] Gray's "Notice of a species of Tupaia from Borneo, in the collection of the British Museum" in the Proceedings of the Zoological Society of London for 1865 (p. 322) may be added to the bibliography of Natuna mammals, as the animal described, though supposed to have been taken in Borneo, is apparently confined to Bunguran Island, the largest of the Natunas.
