"I once saw a most ridiculously tame coaita. It was an old female, which accompanied its owner, a trader on the river, in all his voyages. By way of giving me a specimen of its intelligence and feeling, its master set to, and rated it soundly, calling it scamp, heathen, thief, and so forth, all through the copious Portuguese vocabulary of vituperation. The poor monkey, quietly seated on the ground, seemed to be in sore trouble at this display of anger. It began by looking earnestly at him; then it whined, and lastly rocked its body to and fro with emotion, crying piteously, and passing its long, gaunt arms continually over its forehead; for this was its habit when excited, and the front of the head was worn quite bald in consequence. At length, its master altered his tone. 'It's all a lie,' my old woman. 'You're an angel, a flower, a good, affectionate old creature,' and so forth. Immediately the poor monkey ceased its wailing, and soon after came over to where the man sat." SCARLET-FACED MONKEY. The most singular of the Simian family in Brazil are the scarlet-faced monkeys, called by the Indians Uakari, of which there are two varieties, the white and red-haired. Mr. Bates first met with the white-haired variety under the following circumstances:-- "Early one sunny morning, in the year 1855, I saw in the streets of Ega a number of Indians carrying on their shoulders down to the port, to be embarked on the Upper Amazons steamer, a large cage made of strong lianas, some twelve feet in length, and five in height, containing a dozen monkeys of the most grotesque appearance. Their bodies (about eighteen inches in height, exclusive of limbs) were clothed from neck to tail with very long, straight, and shining whitish hair; their heads were nearly bald, owing to the very short crop of thin gray hairs; and their faces glowed with the most vivid scarlet hue. As a finish to their striking physiognomy, they had bushy whiskers of a sandy color, meeting under the chin, and reddish yellow eyes. They sat gravely and silently in a group, and altogether presented a strange spectacle." Another interesting creature is the owl-faced night ape. These monkeys are not only owl-faced, but their habits are those of the moping bird.
