Length 6 inches^ tail 2*8, wing 3-8, tarsus '7, bill from gape -5. The

I 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 — 
ilf. sinensis, David, from China, and M. latifrons, Sharpe, from Borneo 
and the Nicobar Islands.
