they had been conspicuous neither for their rich variety nor for 

 the beauty of their colouring. I was therefore all the more 

 pleased to find my original conceptions of tropical butterflies 

 realised to some extent in the Kwidschwi forest. Large wonderful 

 papilionidcB, nymphalidce, etc., fluttered in the moist sand on 

 the edges of the rivulets which crossed our path and enchanted 

 us with their glorious, delicate metallic gleaming colours (Salamis 

 macardii), or their creamy velvety black wings decked with 

 striking green or bronze golden hues (Papilio phorcas and 

 vtackinnoni). Others, again, offered exceptional interest through 

 their strongly developed mimicry, like the common Kallima rumia, 

 which, when resting on a branch with wings folded, is very 

 difficult to distinguish from a dry leaf. In these spots, too, 

 away from the native villages, the monkeys showed themselves 

 less timid, so that, after all, we managed to secure a few of 

 them without very much trouble. They were greyish-green 

 in colour, with deep black heads and hands. Strange to say, 

 they appeared to be identical with a variety (Cercopithecus 

 Stuhlmanni), hitherto found only on Mount Ruwenzori. This 

 was a curious coincidence, as the Ruwenzori chain is two hundred 

 kilometres distant from Lake Kiwu, and separated from it 

 by a region exhibiting entirely different conditions of life 

 from the slopes of Ruwenzori and the islands and banks of 

 Lake Kiwu. 



One day the pygmies came into camp bringing their booty, 

 a live, full-grown male monkey. They had carefully shut it 

 into a hastily woven basket. Our attempt to keep the animal 

 alive failed through its savageness. It behaved in a most furious 

 manner, and, attached to the cord which we had placed round 

 its hips, it made such mad leaps and dashes that it injured 

 itself internally and died. Unfortunately we were unable to 

 learn how the Batwa had caught him. One could not ascertain 

 anything from them by direct methods. Tamate maintained 

 that they teased the monkeys by yells and noises and arrow- 

 shots from tree to tree, until they sprang to the earth and 

 could be captured. One day, when returning to camp, I heard
