The islands have perhaps no truly indigenous Mammalia but bats.

The deer of the Moluccas and the pig have probably been introduced.

A species of Cuscus or Eastern opossum is also found at Banda, and this may be truly indigenous in the sense of not having been introduced by man.

Of birds, during my three visits of one or two days each, I collected eight kinds, and the Dutch collectors have added a few others.

The most remarkable is a fine and very handsome fruit-pigeon, Carpophaga concinna, which feeds upon the nutmegs, or rather on the mace, and whose loud booming note is to be continually heard.
