The chord of the largest of the curved tubular flowers of the 
lobelia on which the birds were feeding, is over two inches in 
length. After repeated inquiry among the oldest and best informed 
natives on the island, I was unable to find one who knew or had 
ever heard of the Black Mamo under the native name ‘‘Oo-nuku- 
umu. I did, however, find a few who knew of or identified the 
bird under the name Hoa. 
Vestiaria coccinea Forster. 
A series of ten carefully selected birds and three nests of the 
liwi were secured, which in themselves form a valuable set. 
Taken in connection with the Museum’s long series they assume 
especial interest, making it possible, in another connection, to dis- 
cuss intelligently from specimens in hand, some of the interesting 
problems connected with the evolution and development of the 
species. 
Next to the Apapane and Amakihi, the Iiwi is the species 
most commonly met with on Molokai. They generally frequent 
the Ohia forests, but occasionally they will extend their range 
down, in certain seasons and under favorable conditions, as in 
Wailau and Pelekunu valleys, so as to reach the seashore. ‘They 
are strong flyers, often mounting high in the air. In small loose 
flocks they will thus fly from,one valley to another. ‘Their flight 
over the tallest forest trees can be heard and easily distinguished, 
owing to the whirring noise of their wings, which is supposed to be 
produced by the peculiar truncated form of the primaries. Other 
species of the family, as the A/7matione, having the same shaped 
primaries produce a similar though less marked whirring sound. 
On June 10, while collecting on Wailau pali, I saw a parent 
bird in the brilliant plumage of the adult, feeding an immature
