This bird is easily distinguished from A. cinnamomea, in that 

 the plumage of that species is wholly tinged with cinnamon. 

 The most noticeable difference is in the wings, which, in the 

 new bird, have the primaries dark plumbeous and the coverts 

 for the most part greyish buff. A. sinensis, on the other hand, 

 has the head and tail dark plumbeous and the back dark buff 

 instead of chestnut. This latter bird, too, is smaller in all its 

 dimensions, and has a much more slender bill.

As the history of birds breeding parasitically is of consi- 

 derable interest, and the habits of the Koel do not appear to 

 have been sufficiently studied by Indian ornithologists, I am 

 desirous of recording the result of my own observations on 

 the subject. 



The only information we possess concerning the domestic 



economy of this bird is extremely meagre, if not incorrect. 



The late Dr. Jerdon appears to have been led into error in 



supposing that this Cuckoo "lays* one egg (only) in each
