Although the series of 45 specimens examined exhibits some very- 

 perceptible variations in colors and dimensions, these appear to be 

 chiefly of an individual character. Many of the specimens, however, 

 are in worn or molting plumage, and the various islands are repre- 

 sented so unequally that the comparison can not be considered a satis- 

 factory one. In the three adults from Abingdon Island (obtained 

 April 16, 1888) the inner webs of the rectrices are broadly edged with 

 pale pinkish buff, instead of cinnamon-rufous, but these were skinned 

 from alcohol, the action of which may have extracted or destroyed the 

 rufous color. At any rate, two young birds fiom Abingdon have as 

 much and as bright rufous on the rectrices as those from other islands. 



Measurements of Myiarchus magnirostris.
