We then crossed over to Menado, on our way to Macassar and Java, and I finally quitted the Moluccas, among whose luxuriant and beautiful islands I had wandered for more than three years.
My collections in Bouru, though not extensive, were of considerable interest; for out of sixty-six species of birds which I collected there, no less than seventeen were new, or had not been previously found in any island of the Moluccas.

Among these were two kingfishers, Tanysiptera acis and Ceyx Cajeli; a beautiful sunbird, Nectarines proserpina; a handsome little black and white flycatcher, Monarcha loricata, whose swelling throat was beautifully scaled with metallic blue; and several of less interest.

I also obtained a skull of the babirusa, one specimen of which was killed by native hunters during my residence at Cajeli..
