It is not without considerable diffidence that we have placed this bird as a distinct species from 

 F. ferina. We have, however, examined a very large number of specimens, and find the following 



distinctions to hold good both in young and old birds. The bill in the present species is short er 

 than in F. ferina, the nail broader, and the whole bird rather large)-. In form the nail is much 

 more rounded at the sides, the bill more rounded immediately above the nostrils, and not so deeply 

 channelled in the centre ; also broader measuring across the oilmen.
