CACAJAO 303 



had as a pet died of this malady. Although kept in an airy veranda, 

 it soon lost its appetite; its coat which was long, smooth and glossy, 

 became dingy and ragged, like museum specimens, and its bright scarlet 

 face became dull. When in health, this color extends to the hair on 

 the forehead and temples, and over the cheeks and jaw to the neck. 

 As their hue remained for several hours after the animal's death, he 

 supposed it was due, at least partly, to a pigment beneath the skin, 

 which would probably retain its color after the circulation ceased. 



After witnessing so many proofs of this monkey's morose disposi- 

 tion, he was to meet a very lively individual at the house of a friend. 

 It came from an adjoining room, ran to him and climbed into his lap 

 and nestled there, looking up at him and grinning in the way monkeys 

 have. It was young, and had been captured after its mother had been 

 shot. Its teeth were still incomplete and its face was pale and mottled, 

 the scarlet hue of the adult not having yet appeared. It had been reared 

 with the children and allowed to run about the house. 



The Uakari is one of the many animals the Brazilians call "mortal" 

 or with delicate constitutions in contradistinction to those which are 

 "duro" or hardy. Most of those sent from £ga die before reaching 

 Para, and the difficulty it experiences in accommodating itself to 

 changed conditions probably influences its restricted range, for its limit 

 is an area of swampy woods of about sixty miles in extent, without any 

 barrier to prevent it from wandering farther, except towards the south. 

 One, which he had on his boat on the Rio Negro, and which was quite 

 tame, went on shore one morning at Barra and disappeared in the forest 

 and was gone for twenty-four hours, when he reappeared and walked 

 down the bowsprit, his mode of departure, to his usual place on deck. 

 He had evidently found the forest, which was very different from his 

 humid home on the Japura, uncongenial, and preferred the boat and 

 captivity, to freedom in such a district. 



Schlegel (1. c.) has given the name of Pithecia alba to the monkey 

 described by Bates, as he considered the uncolored drawing in the 

 book represented a distinct species from the Uakari found on the 

 banks of the Solimoens, from the fact that the artist has represented 

 the hair of the animal much longer than it is on the other, and because 

 Bates speaks of it as having a shining whitish hue. It may possibly be 

 that two nearly allied forms of Uakari do exist on these rivers, but 

 until specimens from the two localities are obtained and compared, it 

 is hazardous to describe one as distinct upon an uncolored drawing, 

 and not a very meritorious one at that. It is not easy at times to 

 recognize different species of monkeys when examples are accessible,
