 Trevelyan,'" 



Mr. Seebohm appears to have so satisfied himself as to the 

 correctness of his views on these Chats as to repudiate the 

 determinations of the sexes by field-collectors. Allowing for 

 a few obvious mistakes, the series in the British Museum 

 appears to have been, on the whole, very carefully selected, 

 and in the present case Mr. Seebohm would seem thoroughly 

 wrong in his calculations. 



His ^' adult female" (/) is a fully adult male, and is so sexed 

 by Capt. Trevelyan. It is in the 8th stage of B,, F., & R. 



One of his "immature'" birds is an adult female, the mate 

 of the foregoing male, shot on the same day and at the same 

 place. It is sexed " female " by Capt. Trevelyan. 



The third specimen is immature, being marked as the 

 "young of the two birds."

These are a breeding pair, the male in 7th stage of B., F., 

 & R. The young bird is blacker than the female.
