Almost the only sounds in these primeval woods proceeded from two birds, the red lories, who utter shrill screams like most of the parrot tribe, and the large green nutmeg-pigeon, whose voice is either a loud and deep boom, like two notes struck upon a very large gong, or sometimes a harsh toad-like croak, altogether peculiar and remarkable.

Only two quadrupeds are said by the natives to inhabit the island--a wild pig and a Cuscus, or Eastern opossum, of neither of which could I obtain specimens.
The insects were more abundant, and very interesting.

Of butterflies I caught thirty-five species, most of them new to me, and many quite unknown in European collections.

Among them was the fine yellow and black Papilio euchenor, of which but few specimens had been previously captured, and several other handsome butterflies of large size, as well as some beautiful little "blues," and some brilliant dayflying moths.
The beetle tribe were less abundant, yet I obtained some very fine and rare species.

On the leaves of a slender shrub in an old clearing I found several fine blue and black beetles of the genus Eupholus, which almost rival in beauty the diamond beetles of South America.
