* The construction of a key to the species of silvereyes is rendered very dif- 
ficult by the nature of the characters upon which a number ofethe species are 
“based. Some of the species can be determined only by the actual comparison 
of specimens in fresh plumage. Immediately following the molt, the colors are 
bright and yellowish, but after a few months the feathers become much abraded 
and the colors become duller, dingier and greener.
