100 MESSRS. ROBINSON AND KLOSS ON 



144. Haliaetus leucogaster (Gm.). 



T'\dco leucogaster, Otnelin, Syst. Nat. i, 1788, p, 2.57 (New South 



Wale.s, Mathews). 

 Jfaliaetus hucofjaster, A., p. 17 (Mei'^ui, Malewoon) ; F., p. 23 



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



I., p. 128 (Ko]> Lak). 

 Cuncuma leucoyaster, 13., p. 76 (Junk Sej'^lon). 

 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. h^ucocoryphuB, 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. leucocorypJius from 

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



145. Polioaetus ichthyaetus (Horsf.). 



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



(Java). 

 PoUoaetv^ 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 Fe<thers, 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 hnmilis, Miill. & Schleg., Yerhandelingen, Aves, 1839-44, p. 



47, pi. 6 (Sumatra). 

 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. liumilis, 



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



Himalayas, P. It. pluinbeiis (Hodgs.). 



147. Haliastur Indus intermedius Gumey, 



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

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



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



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