N.B. The last two specimens are in full breediug-pluraage. 



The females also show well-marked differences in colour. 

 Those which in general appearance much resemble the males 

 of form A in non-breeding-plumage, have broad rufescent 

 margins to the feathers of the back, the wing-coverts, and white 

 secondaries, while the tail-feathers are broadly tipped and 

 margined with the same, and there are narrow rufescent edgings 

 to the feathers of the head and neck. These I have referred to 

 form A. The others are altogether of a much darker 

 tone, having the wing- and tail-feathers nearly uniform dull 

 brown, with very faint inconspicuous pale edgings, and the 

 striations of the head and back very broad and dark, with 

 narrow margins, and the whole tone of coloration less rufes- 

 cent. These I refer to form B. Separating twenty-four 

 females solely by differences of colour, I find they measure 

 as follows : —
