Through the kind intervention of Jonkbeer P. J. F. M . Van der Does de Willebois, Agent and Consul-General for the Netherlands in Cairo, five individuals were procured in Borneo and despatched via Singapore for Egypt.

This young male Proboscis Monkey was of a very gentle and affectionate disposition and not at all mischievous ; it reminded us very much of a young Siamese Lutong (Semnopithecus germaini) we once had in captivity, and also of young Gibbons, in the way it held on to one with its hands and evidently liked to be caressed. O n the steamer it had been fed on bananas, so we continued giving it the same food when it would take them, but some days it refused bananas and was given dates and bread, which it ate in small quantities. When eating, the elongated nose moved up and down with the action of tbe jaws, in a ridiculous-looking manner. Its most curious habit was its fondness for water : when set at liberty in |
