After carefully comparing the above considerable series of specimens I am unable to 

 make out satisfactorily differences between specimens from different islands sufficient, 

 in my judgment, to justify separation into local forms. An exception may be made 

 in the case of birds from Haiti, which seem to have the white on the inner primaries 

 decidedly more extended than those from other islands, only one of the four un- 

 doubted males from that island examined having as large a space of dusky on the sub- 

 terminal portion of the innermost (first) primary as that showing the smallest amount 

 from other islands, while in one of the four the innermost primary is entirely white. 

 A larger series from Haiti would be necessary to settle the question, however.
