difficult. It belongs to the genus Erythrura, but it has a smaller bill than 
E. trichroa, though the colors agree fairly well with the description of 
the young of the latter, except for the color of the bill. As the bill is 
wholly black in the Philippine bird, the specimen is more likely to be an 
adult than an immature one. In dimensions and size of bill, the specimen 
is close to an adult of EF. tricolor from Wetter Island, but it differs greatly 
in color and is manifestly out of place there. It probably represents a new 
form, but adult males will be necessary to settle the matter. 
This discovery is extremely interesting. If the species of this 
genus were migratory and if one specimen had been found, it 
would not be very surprising; however, so far as I can make 
out the known species are resident in rather restricted areas. 
The probability is that we are dealing with an unknown resi- 
dent species. Ten individuals of this species being killed in 
one day suggests that collectors must do more field work before 
the species of Philippine birds are all recorded.
