100 MESSRS. ROBINSON AND KLOSS ON 



144. Haliaetus leucogaster (Gm.). 



Falco leucogaster, Ginelin, Syst. Nat. i, 1788, p, 257 (New South 



Wales, Mathews). 

 Haliaetus leucogaster. A., p. 17 (Mergui, Malewoon) ; F., p. 2.3 



(Malay Peninsula) ; H., p. 144 (Koli Sarnui and Koh Pennan) ; 



I., p. 128 (Koh Lak). 

 Cuncuvia leucogaster, B., p. 76 (Junk Seylon). 

 Haliaetus leucocoryphus, F., p. 25 (Langkawi Ids.). 



Common along the sea-coast everywhere. 



Re-examination of the two specimens from Langkawi, for- 

 merly identified by us as H. leucocoryiohus, convinces us that they 

 are large immature specimens of this species. We have also examin- 

 ed the specimens on which rest the record of H. leucocoi^yplius from 

 Borneo, and do not consider them also to be other than this species. 



145. Polioaetus ichthyaetus (Horsf.), 



Falco ichthyaetus, Horsf., Trans. Linn. Soc, xiii, 1821, p. 136 



(Java). 

 Polioaetus ichthyaetus, A., p. 16 (Pakchan) ; E., p. 113 (Patani) ; 



F., p. 30 (Malay Peninsula); G., p. 151 (Ratburi and Petcha- 



buri) ; H., p. 144 (Bandon) ; L., p. 94 (Junk Seylon and Ghirbi); 



Hume, Stray Feithers, ix, 1880, p. 120 (Panguga). 



Our experience of this species is that it is never found in 

 heavy jungle, but is.fairly common on the sea coast and on rice fields. 



146. Polioaetus humilis humilis (Miill. & Schleg.). 



Falco humilis, Miill. & Schleg., Verhandelingen, Aves, 1839-44, p. 



47, pi. 6 (Sumati'a). 

 Polioaetus humilis, H., p. 90 (Bandon). 

 More of a jungle bird than the preceding. Peninsular Siam 



birds are probably to be referred to the Malayan race, P. Jmmilifi, 



rather than to the much larger bird from continental India and the 



Himalayas, P. h. plumbeus (Hodgs.). 



147. Haliastur indus intermedius Gurney. 



JIaliastur indus intermedius, Gurney, Ibis, 1865, p. 28 (Java). 

 Haliastur indus, A., p. 22 (Mergui, Banfctsoon) ; B., p. 76 (Junk 



Seylon) ; 0. ii. p. 201 (Tenasserim) ; D., p. 58 (Patchung and 



Patani) ; G., p. 151 (Ratburi and Petchaburi).
