The introduction may have been very recent, as in a fertile and unoccupied island such an animal would multiply rapidly.
The only other mammals obtained were an Eastern opossum, which Dr.Gray has described as Cuscus ornatus; the little flying opossum, Belideus ariel; a Civet cat, Viverra zebetha; and nice species of bats, most of the smaller ones being caught in the dusk with my butterfly net as they flew about before the house.
After much delay, owing to bad weather and the illness of one of my men, I determined to visit Kasserota (formerly the chief village), situated up a small stream, on an island close to the north coast of Batchian; where I was told that many rare birds were found.

After my boat was loaded and everything ready, three days of heavy squalls prevented our starting, and it was not till the 21st of March that we got away.
Early next morning we entered the little river, and in about an hour we reached the Sultan's house, which I had obtained permission to use.

It was situated on the bank of the river, and surrounded by a forest of fruit trees, among which were some of the very loftiest and most graceful cocoa-nut palms I have ever seen.

It rained nearly all that day, and I could do little but unload and unpack.

Towards the afternoon it cleared up, and I attempted to explore in various directions, but found to my disgust that the only path was a perfect mud swamp, along which it was almost impossible to walk, and the surrounding forest so damp and dark as to promise little in the way of insects.
