VISCOTJNT WALDEN ON THE BIEDS OF CELEBES. 37 



species. No authentic account of its occurrence in Celebes has as yet been published, 

 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. Gmelia gave that title to the 

 Javan Hawk, described by Latham fi-om an individual which flew on board a vessel off 

 the coast of Java. Mr. J. H. Gurney informs me {in 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. E. 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 Jive caudal bands. 



Mr. Blyth tells me that he considers his B. pygmanis to be the same as F. poliogenys, 

 Temm., and that Mr. Eyton's description of Astur barbatus sufficiently applies to 

 B. pygmceus.
