South China, northwards to Wanchow, and in Hainan. I can 

 find no distinctive characters between the Chinese and Bengalese 

 specimens ; but birds from Siam have the back chestnut as well as 

 the scapulars, = C. eurycercus, A. Hay. The Java bird is coloured 

 like ours, but is of larger size, and has a much larger bill, = (7. rufi- 

 pennis, Illig. (bubutus, Horsf.).

South China, Hainan, and Formosa. Birds from the same 

 locality extremely variable in size. Our birds agree with speci- 

 mens from Bengal, Malacca, Java, and some of the isles. From 

 Timor I have seen a larger species, the C. moluccensis, Bernst. (me- 

 dius, G. R. Gr.), which by its similar immature plumage is con- 

 nected with the present species, but in size almost approaches the 

 foregoing. The second or streaked plumage of the C. bengalensis 

 is peculiar for the enormous length of the upper tail-coverts, which 

 nearly cover the surface of the tail to its end. In the first or 

 nestling plumage, and in the adult or rufous-and-black plumage, 

 these coverts are short. In this intermediate dress it is recognized 

 as the C. lepidus of Horsfield.
