Tins swelling of the front of the face in the skull slightly reminds us ef a greater one which characterises the Dog-faced Baboons, and, moreover, the similarity is increased by the fact that the upper eye (canine) tooth presses the tooth behind the lower ej'e tooth backwards. These little peculiarities are inherited gifts, for the Nasalis and the Baboon probably came from a common ancestor. Perhaps the great fleshy of the Semnopithecus Nasalis is a relic of the long face of the ancient Baboon. Shorten the bones of the Baboon's nose, and leave the soft parts, and there would be left sometliing like the queer features of the Monkey now mider consideration.

These are rounded so as to afibrd comfortable rest, especially as they are covered by the callosities or pads.

The Dyaks call this Monkey the Kaha, tor thLs is the sound which they make when in companies in the woods by the side of the swamps and jungles. There they live a restless life at sunrise and sunset, being quieter in the heat of the day, and crying out at each other.
