(While I quite agree that Hellmayr is undoubtedly right that this form is 

 obviously different from F. intermedia, with which Berlepsch and I had identified 

 it, it is certainly a subspecies of F. grisea, together with intermedia, tobagensis, 

 and others. Hellmayr, in htt., now agrees with my opinion.)
