to the lower jaws, and belong, in all other essential points 

 of structure, to the Lemur family, which has not a single 

 representative in the New World. The Ei-as have teeth 

 of the same number, and growing in nearly the same 

 position, as their near relatives the Sai-miris. I obtained, 

 moreover, yet stronger proof of this close relationship be- 

 tween the night and day monkeys of America, in finding 

 a species on the Upper Amazons which supplies a link 

 between them. This one had ears nearly as short as 

 those of the night apes, and also a striped forehead ; the 

 stripes being, however, two in number, instead of three : 

 the colours of the body were very similar to those of the 

 well-known Chrysothrix sciureus, and the eyes were fitted 

 for day vision. 



Barrigudo Monkeys.- — Ten other species of monkeys 

 were found, in addition to those already mentioned, in 

 the forests of the Upper Amazons. All were strictly 

 arboreal and diurnal in their habits, and lived in flocks, 

 travelling from tree to tree, the mothers with their children 

 on their backs ; leading, in fact, a life similar to that of 

 the Pararauate Indians, and, like them, occasionally 

 plundering the plantations which lie near their line of 

 march. Some of them were found also on the Lower 

 Amazons, and have been noticed in former chapters of 

 this narrative. Of the remainder, the most remarkable 

 is the Macaco barrigudo, or big-bellied monkey of the 

 Portuguese colonists, a species of Lagothrix. The genus 

 is closely allied to the Coaitas, or spider monkeys, having, 

 like them, exceedingly strong and flexible tails, which are 

 furnished underneath with a naked palm like a hand, for 

 grasping. The Barrigudos, however, are very bulky 

 animals, whilst the spider monkeys are remarkable for 

 the slenderness of their bodies and limbs. I obtained 

 specimens of what have been considered two species, one 

 (L. olivaceus of Spix ?) having the head clothed with gray, 

 the other (L. Humboldtii) with black fur. They both 

 live together in the same places, and are probably only 

 differently-coloured individuals of one and the same 

 species. I sent home a very large male of one of these 

 kinds, which measured twenty-seven inches in length 

 of trunk, the tail being twenty-six inches long ; it was 

 the largest monkey I saw in America, with the exception 

 of a black Howler, whose body was twenty-eight inches in 

 height. The skin of the face in the Barrigudo is black
