TYPE SPECIMENS OF BIRDS 29 



ments cited fit only No. 9470. However, since in the work quoted the 

 authors did not consistently take their measurements from the specimen 

 used for description of plumage, but rather from whatever bird was largest 

 or most conveniently measurable, both skins are here listed as cotypes.
