FROM THE GANGES TO THE GODAVERI. 191 



After we left the Narra, our men found numerous nests of 

 Butorides javanieus and a few of Ardetta sinensis. Laticilla 

 burnesi had apparently just finished breeding at the end of 

 July, as we noticed several young birds only just able to fly, and 

 the sexual organs of the old birds we examined had almost 

 resumed their ordinary proportions. 



Since the above was written Mr. Doig found a pair or two 

 Ardetta cinnamomea breeding in the Narra.

On the distribution of birds, so far as it is at present known, 

 throughout the hilly region which extends from the Rajmehal 

 Hills to the Godaveri Valley.

Having spent thirteen camping seasons in the districts 

 included in the wide, and for the most part little known, region 

 which is contained between the above-indicated limits, I 

 think the time has arrived when I may venture upon pub- 

 lishing a general sketch of the distribution of the birds which 

 occur there. This region will be found to correspond very 

 nearly with the Bengal sub-province as defined by Mr. W. T. 

 Blanford.* 



Hitherto no attempt has been made to prepare a complete 

 list of the birds found in it — the nearest approach in that 

 direction having been made by myself in my list of Chutia 

 Nagpur birds, f Since that list was published, a good many 

 additional species have been obtained, and several important 

 changes in the nomenclature^ and identification then adopted 

 have become necessary. 



Chutia Nagpur occupies a nearly central position in the 

 area now under description, and its Avifauna may be regarded 

 as being fairly representative, but it will be seen that the 

 present list includes many species not found in that division. 



In preparing this list 1 have thought it, on the whole, safer 

 to make no entries of localities, except those of which there

 names in which I was not sure whether Mr. Ball would accept my corrections. — Ed.
