368 Mr. J. H. Gurney's Notes on 



The inner lining of the wing is white, with narrow trans- 

 verse brown bars at small intervals, much resembling the bars 

 on the breast in their character and arrangement. 



The upper surface of the tail is crossed with four bars of 

 dark brown, the lowest being terminal, with the exception of 

 a narrow white tip to the rectrices ; these dark bars, which 

 are all of nearly equal width, are alternated with other bars 

 of similar width but of a paler brown ; and in the centre of 

 each of these paler bars is a pure white spot, including a por- 

 tion of the shaft of the feather, which is there white also ; 

 these spots, which are largest on the upper portion of the 

 tail, and diminish in size as they approach its extremity, 

 occur on all the rectrices. 



The underside of the tail shows five dark transverse bars, 

 the intervals between which, including the portions of the 

 feather-shafts which they comprise, are white, as are also the 

 under tail-coverts. 



The whole remainder of the undersurface of this specimen 

 is white, with narrow transverse grey bars at small intervals, 

 the bars themselves, and also the intervals between them, 

 being much narrower on the throat than elsewhere. 



The immature female is dark brown on all the upper parts 

 which in the adult male are grey ; but the feathers of the fore- 

 head and of the sides of the head and neck are broadly mar- 

 gined with white; the hindermost tertiaries and a few adja- 

 cent feathers of the back are also slightly tinged with rufous, 

 especially at the tip. 



The tail has five dark transverse bars on the upper, and 

 six on the under surface, the lowest bar being terminal ; in 

 the intermediate paler species the shafts only of the rectrices 

 are white. 



The breast shows the appearance of a few adult feathers, 

 resembling those on the breast of the adult male; the re- 

 maining plumage of the underparts, which is still immature, 

 is also transversely barred, but the bars are wider apart than 

 in the adult, and slightly sagittate in their arrangement ; the 

 feathers on the crop also show a narrow brown shaft-mark ; 

 and both on the breast, abdomen, and thighs the white in-
