to get hungry, and whined for their mother, who took them, and after having nursed them returned them to their “papa.” In fact, the father did all the hard work, and the mother merely fed them. In this instance this domestic happiness was cut short, for the mother was weakly, no wet-nurse was to be had, and the little ones sank and died. In their native state they lead an arboreal life, and assemble in groups of six or seven, climbing up the tallest trees, and jumping from bough to bough, showing the greatest activity, like and greater than that of Squirrels. So rapidly do they move from branch to branch, and from tree to tree, that the eye fails to follow them readily. They are recognised at once by their long tuft of whitish hair, which sticks out from the side of the head, and almost hides the ears. The size of the whole animal is about that of a small Squirrel, and the tail is very long, bushy, and prettily marked with alternate rings of ash-colour and of black fur. The head is small, the eyes are gentle-looking, and the nose is flat, the face being black. The fur of the body is darkish brown, with different shades of colour for each hair, which is dusky at its root, reddish in the middle, and grey at the tip. There are very different stories told regarding their intelligence and affection. Some naturalists assert that they are incapable of affection towards man, even to the hand that feeds them. Swainson says “it mistrusts all, and treats as indifferently those whom one would think it well knew and those who are strangers; neither does it show much intelligence, although it is attentive, and suspicious of everything that is passing. When under the influence of fear it strives to conceal itself, uttering a short but piercing cry; at other times it hisses.” The name Ouistiti has been given to this Monkey, and the Portuguese of the Amazon districts called it the Sanglain, whilst Europeans term it a Marmoset. THE CLOAKED MARMOSET.[110] The word “humerale” is to be translated a part of the harness on the shoulders, or a graduate’s cloak, according to an old Latin dictionary, and thus far a fit name has been given to a little Monkey thus noticed by Mr. Bates in his work on the Amazons:--
