limbs of the Marimonda in the huts of the natives on the Orinoco ; and, at Emeralda, 

 he found in an Indian hut a collation of their roasted and dried bodies, prepared as 

 the pieces de resistance for a ' harvest home.' 



" In Lagothrix, the head is rounder than it is in Ateles, the hands are provided 

 with thumbs, such as they are, but the tail is still long and prehensile, and the under 

 surface at the tip is naked. The species of this genus are of some size. The Caparro 

 which inhabits the banks of the Guaviare, one of the streams that flow into the Ori- 

 noco, is two feet two inches in length, without including the tail. The head is very 

 large and round in proportion. 



" Cebus next claims our attention. In this form we find the tail beginning to lose 

 somewhat of its prehensile powers, and no longer bared at the tip to add to its sensi- 

 bility as an organ of touch. In lieu of this, the strength is thrown into the limbs, 

 which are well developed, and the anterior hands are remarkably well formed — though, 

 still, less perfectly than those of the Old World monkeys. The first of the five fingers 

 is become more thumb-like, and the palms of the extremities both before and behind 

 are endowed with much sensitiveness. These sylvans are excellent climbers, and of a 

 surprising agility. 



" Of these Cebi, the horned sapajou, with the hair of the forehead standing up so 

 as to give the animal the appearance of having a London waterman's cap on, is one 

 of the largest, while the Ouavapavi des cataractes, which is very mild and intelligent, is 

 of small size. We remember once to have heard of a sort of compact which was said 

 to have been entered into between a monkey and a pig, the latter of which carried the 

 monkey a certain number of times round an orchard, in consideration of the monkey's 

 climbing the apple-trees, and giving them a shake for the benefit of the porker. 

 Though not very old at the time, we gave the narrator credit for being blessed with a 

 very lively imagination, albeit the story was told gravely and vouched as a fact. But 

 Humboldt actually saw, at Maypures, one of these domesticated Ouavapavis, obtaining 

 his rides apparently without any such understanding ; for this clever monkey used to 

 bide his time, and every morning caught a luckless pig, which he compelled to per- 

 form the part of his horse. Seated on pigback did he majestically ride about, the 

 whole day, clinging to his bristly steed as firmly as ever the Old Man of the Sea clung 

 to Sinbad, not even giving poor piggy a respite at meal-times, but continually be- 

 striding him all the time he was feeding in the savanna that surrounded the Indian 

 huts. A missionary had another of these riders ; but the missionary's monkey had 

 laid the strong hand of possession on a comfortable cat which had been brought up 

 with him, carried him well, and bore all his felestrian exploits with patience and good 

 humour. 



" The tail, which has become less and less prehensile in the genera last noticed, 

 becomes in Callithrix no longer capable of use as a support. The pretty playful little 

 Siamiri, whose length hardly exceeds ten inches exclusive of the tail, which reaches 

 thirteen or fourteen, winds that appendage like a boa round its body and limbs, re- 

 minding the zoologist in some degree of the mode in which the white-fronted Lemur 

 disposes of his ; and we now begin to observe, moreover, traces of insectivorous and 

 carnivorous appetite. The Macavacahow, at the sight of a bird, is roused at once 

 from its apparent apathy ; darting on its victim like a cat, it secures the prize and 

 swallows it in an instant, with all the actions that mark the beast of prey. 



" In the Dourocouli, the Cara rayada of the missionaries, we observe traces of the 

 cat in appearance, voice and manners. This curious animal is nine inches in length,
