1 avail myself of Mr. Hume's capital description of this Falconet, more 

 especially as it includes the plumage of the very young bird, which I have 

 never seen. 



The Black-legged Falconet occurs in Tenasserim as high as 14 north 

 latitude. 



It is met with in the Malay peninsula, Sumatra, Java and Borneo, and, 

 according to Dr. Tiraud, in Cochin China. 



This species is similar to the preceding in habits, and like it deposits its 

 eggs in the hole of a tree. 



Allied species described since Mr. Sharpe wrote his Catalogue are 

 M. sinensis, David, from China, and M. latifrons, Sharpe, from Borneo 

 and the Nicobar Islands.
