116 LIST OF DIURNAL BITtDS OF PKET. 



According to the measurements whicli I subjoin there 

 would appear to be amongst these specimens one female and 

 five males, though of the latter two have been marked " ? " 

 by the collector. 



The males are entirely in the first year's plumage, except 

 one, which has, to some extent, acquired the adult dress, espe- 

 cially as regards the quill-feathers and greater coverts of the 

 wing, and also the tail, which is grey, with the exception of 

 some remains of brown cross-barring. 



The female and the four younger males all show more or 

 less of the dark cross bars on the central rectrices ; but in 

 three of the males it is very indistinct, and in one of the 

 three so effaced as to be almost indistinguishable; it is, how- 

 ever, clear to me that this is merely the effect of the feather 

 becoming worn and faded as the season for moulting has 

 approached. I greatly doubt a similar effect being ever pro- 

 duced in this species by the age of the bird, as suggested by 

 Mr. Seebohra. 



Immature specimens of C. spilonotus in which the dark 

 cross bars have been removed by fading and attrition from 

 the central rectrices cannot, in my opinion, be discriminated 

 with certainty from immature specimens of C. aruginosus.
