14 ON A COLLECTION OF BIRDS 



tion there are two with red heads and the third with a brown 

 one. It may be worth of notice , that the latter is labelled 

 as a male, while of the first two the one is labelled as a 

 male , the other as a female. As Count Salvadori has 

 already called attention upon this point (Ucc. di Sum. p. 

 170), it would not be very surprising to find one day 

 that the birds are not erroneously labelled but that really 

 very old females would assume the plumage of the adult 

 male.

336, pi. 8, fig. 1 ; — Snelleman, Sum. Exp. Vogels, p. 33 



(1884). 

 Hapalarpactes macloti, Salvad. Ucc. di Sumatra, p. 177 (1879), 



10 specimens. 



» Iris dark brown , circle round the eye ultramarine, bill 

 blood-red, gonys green, feet orange-yellow. Native name: 

 Kassumbary 



Amongst the four specimens labelled cT is one with 

 back and rump entirely green and without any indication 

 of being a young bird , while among the females is one with 

 a red rump. I therefore rather believe in a collectors mistake 

 when fixing the labels to the birds.
