VISCOUNT WALDEN ON THE BIRDS OF CELEBES. 37

while Professor Schlegel and Mr. Wallace restrict its range to Bourou, Ceram, and 
Amboyna.

The designation F. indicus, Gm., is rejected by Professor Schlegel (Mus. Pays-Bas, 
Buteones), on the ground of its being undeterminable. Gmelin gave that title to the 
Javan Hawk, described by Latham from an individual which flew on board a vessel off 
the coast of Java. Mr. J. H. Gurney informs me (im epist.) that, having compared 
Latham’s description with the three Asiatic species of Poliornis, he agrees with the late 
Mr. Strickland (and consequently with Mr. G. R. Gray, List B. Mus. p. 68, 1848) in 
identifying it with F. poliogenys, Temm. “ Latham’s description agrees in all respects,” 
continues Mr. Gurney, “‘ except that he speaks of five transverse bars on the tail, and I 
have not seen more than four, and in one specimen only three.” My Celebean and 
Gilolo examples only possess three bars. But in the ‘Fauna Japonica’ Professor 
Schlegel states that this species has four or five caudal bands. 
Mr. Blyth tells me that he considers his B. pygmeus to be the same as F. poliogenys, 
Temm., and that Mr. Eyton’s description of Astur barbatus sufficiently applies to 
B. pygmeus.
