-r48. Spizaetus limnaetus. 



Sphaetns limnaetus (Horsf .) ; Sharpe, torn. cit. p. 272. 



An adult male in tlie melanotic phase, exactly agreeing 

 with Horsfield's type of the species from Java, was collected 

 on January 12th, 1910, at Lam-ra. 



The species is fairly common throughout the Peninsula, 

 keeping to low country and to the lower ground, while the 

 smaller and handsomer S. alboniger is found on the hills and 

 in deep jungle. 



-4-49. Spilornis pallidus. 



Spilornis pallidus (Walden) ; Sharpe, tom. cit. p. 290, 

 pi. ix. 



After examination of a large series of specimens from the 

 whole Malay Peninsula, we are forced to the conclusion that 

 only one form is represented, and that, although it does not 

 precisely agree with any definite species, it comes nearest 

 to S. pallidus of Walden from Borneo. That, however, was 

 described on the strength of an extremely young specimen 

 which does not shew the real characters of the species. 



The series before us varies greatly both in general intensity 

 of coloration and in the nature and intensity of the spots 

 on the lower surface, which in the majority of the specimens 

 are numerous and somewhat ill-defined at the edges, in this 

 respect approaching S. rutherfordi, originally described from 

 Hainan, but apparently spread all over Indo-China. Some 

 specimens, however, notably one from the Larut Hills, 

 Perak, are very much darker, almost apj)roaching Javan 

 birds {S. bido Horsf.). The whole genus stands greatly in 

 need of revision, 



+ 50. BUTASTUR INDICUS. 



Butastur indicus (Gm.) ; Sharpc, tom. cit, p. 297. 

 We have obtained this species twice from Langkawi, in 

 November 1907 and February 1909.
