The titi of the Oroonoko (simia sciurea), ill- 

 drawn hitherto, though well known in our col- 

 lections, is called bititeni by the Maypure In- 

 dians. It is very common to the South of the 

 cataracts. It's face is white ; and a little spot 

 of bluish-black covers the mouth and the point 

 of the nose. The litis of the most elegant form* 

 and the most beautiful colour (with hair of a 

 golden yellow), come from the banks of the 

 Cassiquiare. Those that are taken on the shores 

 of the Guaviare are large and difficult to tame. 

 No other monkey has so much the physiognomy 

 of a child as the iiti ; there are the same expres- 

 sion of innocence, the same playful smile, the 

 same rapidity in the transition from joy to sor- 

 row. It's large eyes are instantly filled with 

 tears, when it is seized with fear. It is ex- 

 tremely fond of insects, particularly of spiders. 

 The sagacity of this little animal is so great, that 

 one of those we brought in our boat to Angos- 

 tura distinguished perfectly the different plates 

 annexed to the Tableau elementaire d'Histoire 

 naturelle of Mr. Cuvier. The engravings of 

 this work are not coloured ; yet the till advanced 

 rapidly it's little hand in the hope of catching a 

 grasshopper or a wasp, every time that we 

 showed it the eleventh plate, on which these 

 insects are represented. It remained in the 

 greatest indifference, when it was shown engrav- 

 ings of skeletons or heads of mammiferous ani-
