164. Huhua sumatrana (Raffles). 



Strix mmatrana, Raffles, Ti-ans. Linn. Soc xiii, 1822, p. 279 



(Sumatra). 

 Bubo orientalis, A., p. 31 (Hankachin, Pakchan headwaters ) ; 



C. ii, p. 153 (S. Tenasserim). 

 Huhua orientalis, F., p. 31 (Trang). 



We have examined series from Sumatra, Borneo and the 

 north and south of the Malay Peninsula and can detect no differen- 

 ces in size. Malay Peninsular and Sumatran birds are identical and 

 will, therefore, have to be called H. sumatrana, though whether 

 they are truly distinguishable from the typical H. o. orientalis 

 Horsf., from Java, i'^, in the absence of specimens, still an open 

 question. The Bornean birds do not differ in size from the others, 

 but are less distinctly barred beneath. Schlegel* has named the 

 bird from Banka, B. o. minor, which seems to be identical with the 

 Sumatran and Malay Peninsular bird. 



165. Bubo coromandus klossi Robinson. 

 Bubo coromandus klossi, Robin.son, Journ. F. M. S. Miis. iv, 1911,

Siam. ii, 1916, p. 58 (S. W. or Peninsular Siam) ; M.I, p. 26 



(Peninsular Siam). 



" Iris yellow ; bill greenish horny, black at base ; feet leaden." 

 Total length, d". 540, 9 545 ; wing, 6 399 (type) 380, 9 385 ; 



bill from gape, cS 46 (type) 43, 2 46 m.m. 



This race is at present known from seven specimens only, 



ranging from Koh Lak in S. W. Siam to Malacca ; it differs from the 



Indian form in its very much darker colour. 



Otus sagittata (Cass.). 



Ephialtes sagittatus, Cass., Proc. Ac. Nat. Sc. Philad. iv., 1850, 



p. 121 (Malacca). 

 Scops sagittatus, A , p. 35 (Malewoon) ; C, ii, p. 156 (Malewoon). 



A species of extreme rarity which, however, is certain to be 



found in the area ; we have a single male from Bukit Tangga, Negri 



Sembilan, 



Mus. Pay.s Ba.s, Oti. p. 13 (1862), p. 5 (1873).
