The first mention of the occurrence of this species in Celebes Avas made 
by Prof. Beichenow in reference to a specimen brought from that island by 
V. Faber, and later, in ansAver to a communication from Prof. W. Blasius, Dr. 
BeichenoAV confirmed his first note (fO). A second specimen in the Dresden 
Museum, labelled Manado by van Musschenbroek, is in immature plumage, 
and corresponds fairly Avell Avith one described by Hume, Str. F. IX, 274. We 
have described it above. 
Probably because the immature plumage of this species remained for a long 
time unknown, there has been much misconception touching the specimen in 
the Leyden Museum from Luzon referred by Schlegel to this species. Gur- 
ney (f 2) included this specimen under his Spizaetus philippinensis , overlooking 
the much longer tarsi and tail of that species; and other authorities have fol- 
loAved him. Consequently the PhilijApine Islands have been generally struck 
out of the range of this species. There is no reason to doubt the correctness of 
SchlegePs identification of the specimen from the Philippines, and in the
