Tiiis handsome red moiikev is called bv the Dyaks of Sarawak 

 ' Jellu mirali,' and by the Kayans ' Kalasi,' and it is common 

 everywhere. U is usually seen in large numbe's, and some 

 thirty or forty often pass one in the jungle, darting from 

 branch to branjh and making a tremen lous noise. They will 

 sometimes, when barked at by dogs, attack a dog and inflict 

 a very bad bite. They ascend the mountains to the 

 height of 3000-ft., but at that height the colour of their hair 

 becomes a much deeper red. They are very destructi\'e in 

 fruit gardens.
