F. pojana, Savi. 



B. albus, Daudin. 



B. mutans etfasciatus, Vieillot. 



B. septenlrionalis, medius, et murum, Brehm. 



B. communis, Cuvier. 



B. Swainsonii, Pr. Bonap. 



B. montanus, Ruppell. 



B. ruf venter, Jerdon. 

 Hab. Northern hemisphere ; rare and to the northward only in 

 America. The loftier hills only in India. 



Remark. We doubt if this can in all cases be satisfactorily distin- 

 guished from the preceding species, and certainly not some European 

 specimens from some Himalayan or Nilgiri examples. 



63. B. pygm;eus, Blyth, J. A. S. XIV, 177. 



Syn. ? Astur barbatus, Eyton, from Malacca (referred by Mr. 

 G. R. Gray to the Japanese Falco or Poliornis pyrrhogenys, 

 Temminck and Schlegel). 

 Hab. Tenasserim provinces ; Malayan peninsula? 

 Remark. This is a tr,ue long- winged Buteo, though resembling 

 Poliornis in some respects ; and Mr. Eyton' s description sufficiently 

 well applies to it, allowing for some variation of plumage from the 

 Society's specimen. The admeasurements in particular correspond. 



Genus Poliornis, Kaup. 



64. P. teesa (Hardwicke's III. Ind. Zool). 



Syn. Circus teesa, Franklin. 

 Astur hyder, Sykes. 

 Zuggun Falcon, Latham. 



P.fasciatus (?), A. Hay, Madr. Journ. XIII, 146. 

 Tisa (or Teesa, from the voice), H. 

 Hab. Plains of India, where very abundant : never met with on 

 the mud-soil of Lower Bengal, though appearing immediately this is 

 quitted in a westerly direction : Tenasserim provinces ; Malayan penin- 

 sula? 



Remark. Specimens from Tenasserim and from S. India having 

 large whitish supercilia appear to agree with Lord A. Hay's description 

 of his P.fasciatus from Malacca; and the Astur barbatus, Eyton, 

 from Malacca, referred to the Japanese P. (?) pyrrhogenys by Mr.
