340 Conspectus of the Ornithology of India. [No. 4. 



G. R. Gray, we have already dubiously assigned to No. 63. The pre- 

 sent genus, on mature consideration, we have placed next to Buteo, the 

 lengthened cere separating it from the Accipitrin^e among which it 

 is included by Mr. G. R, Gray and others, following Col. Sykes. 

 Major Franklin referred it to Circus, and Prof. Kaup regards it as 

 subordinate to Circdetus. 



Subfam. HALIAETINiE. 



Genus Pandion, Savigny. 



65. P. haliaetus (Gould's B. E. pi. 12). 



Syn. Falco haliaetus, L. 



F. carolinensis, F. cayanensis,et F. arundinaceus, Gmelin, 



F. piscator, Brisson. 



Aquila piscatrix, Vieillot. 



Aq. balbuzardus, Dumeril. 



P.fluvialis, Savigny. 



P. atnericanus, Vieillot. 



P. alticeps et P. planiceps, Brehm. 



P. indicus, Hodgson. 



P. icthydetus, Kaup (apud G. R. Gray). 



Bengal Osprey, Latham. 



Mdtch-Morol (' Fish Tyrant'), and Bulla, B. ; Mu- 



cherera, H. (Jerdon) ; also Match-mangd, H. : 



Won-lety Arakan (Phayre). 



Hab. Of general distribution; the Australian race (P. leuco- 



cephaluSy Gould, which according to M. Schlegel is found also in Japan 



and in the eastern Archipelago), alone slightly differing. Common 



throughout India, in all suitable localities. 



Remark. The Osprey is a very peculiar form among the Falconidce, 

 and wants the projecting super-orbital bone which is so characteristic 

 of (we believe) all the rest. The next genus approximates Pandion in 

 the adaptation of structure for piscivorous habits, but is nevertheless 

 very distinct, and much more nearly affined to true Haliaetus. 



Genus Pontoa^tus, Kaup. 



66. P. icthyaetus (Horsf., Zool. Res. in Java, pi. ). 



Syn. Falco icthya'etus, Horsfield. 

 Haliaetus plumbeus, Hodgson.
