252 Drs. O. Finsch and A. B. Meyer on 
Examples from Milne Bay seem to have the brownish- 
violet breast-shield rather darker and the parts immediately 
below also darker than examples from the Astrolabe Moun¬ 
tains. In the latter also there appears to be a yellowish 
nuance on the green throat-feathers, instead of the bluish 
nuance of the former. The Milne-Bay specimens measure 
about half a millimetre more in the length of the wing, and 
also show a rather more yellowish nuance on the undersides 
of the wings and tail when the direction of the eye is parallel 
to the light falling upon it. But all these apparent differences 
are very slight, and there is not sufficient evidence of their 
constancy to separate the birds as local forms. At the same 
time it is right to notice these small differences occurring in 
neighbouring localities in order to arrive at a correct know¬ 
ledge of the variation of species in connection with geo¬ 
graphical distribution.
