The Ouarine and the Alouate are the largest four-handed animals belonging to the New Continent: they surpass the size of the largest monkey, and approach that of the baboon. They have prehensile tails and are consequently of the sapajous family, in which they hold a very distinguished rank, not only with regard to stature, but also by voice, which resounds like a drum, and may be heard at a very great distance. Marcgrave informs us, "that every morning and evening the ouarines assemble in the woods; that one among them seats himself on an elevated place, makes a sign with his hand to the rest to seat themselves round him; that as soon as he sees them all seated, he begins an oration with so quick and loud a voice as to be heard at a great distance, and it might be imagined they were all making a noise together, but during the whole time the rest keep a profound silence; that when he has ended, he makes a signal to the others to reply, and immediately they all set up a cry together, till such time as by another sign with his hand, he orders them to be silent, and which they instantly obey; that then the first renews his discourse, or song, which, when finished, and the others have paid the utmost attention to it, the whole assembly break up." These circumstances, of which Marcgrave says, he has many times been an eye-witness, may possibly be exaggerated, and seasoned a little with the marvellous. The whole, probably, is only founded on the frightful noise these animals make; they have in their throats a kind of bony drum, in the cavity of which the sound of the voice thickens, encreases, and forms a kind of howling reverberation; upon which account these sapajous have been distinguished from the rest by the name of howlers. We have never seen the ouarine, but we have the skin and the dried foetus of an alouate, in which the instrument of the loud noise he makes, that is to say, the bone of the throat, is very apparent. According to Marcgrave, the face of the ouarine is broad, the eyes black and sparkling, the ears short and round, and a tail naked at the extremity, which holds firmly whatever it encircles; the hair of the body is black, long, and glossy; it is much the longest under the chin, and forms a kind of round beard; the hair on the hands, feet, and a part of the tail, is brown. The female is of the same colour as the male, and only differs from him in being smaller. The females carry their young on their backs, and thus loaded leap from branch to branch and from tree to tree. The young ones clasp the mother round the narrowest part of the body with the hands and arms, and thus remain firmly fastened, while she keeps in motion. These animals are so wild and mischievous, that they can neither be tamed nor subdued; they bite dreadfully, and although they are not among the carnivorous animals, yet they excite fear by their frightful voice and ferocious air.
