hyenas and jackals only being found. Little noc- 

 turnal animals are more common, but they are very 

 difficult to get at. Reptiles abound in the forest. 

 There are a great many species of snakes, the greater

 snakes one of the most to be dreaded is the Clotho

 name of Siturophaga grayii. I have often seen this 

 snake coiled up and resting on the branches of trees 

 Under water. 



Lizards are also abundant in some districts, and it 

 is amusing to watch how they jorey on the insect

 are of wonderful diversity of form. Some of them are 

 so large, and their webs so strong, that birds are
