“Iris brown, bill pale greenish horn, tarsi white, 
tinged with greyish pink, claws pale horn.” 
After comparison with a considerable number of speci- 
mens of this group from all parts of the Malay Peninsula, 
south to Singapore Id. and from Sumatra and Borneo I have 
come to the conclusion that these two birds must be provi- 
sionally referred to this race described by Hodgson from the 
Eastern Himalayas. The toes are slightly, though not very 
markedly, more feathered than in the southern birds but the 
size wing 171 and 166 so much exceeds that of any specimen 
of O. b. lempyi (Horsf.) that it is impossible to identify them 
with that form whose wing never exceeds 157 mm. The two 
specimens differ widely iter se, one having the forehead largely 
buff while the colour beneath is deeper with strongly marked 
dark shaft stripes to the feathers of the belly while the other 
is much paler with transverse vermiculations on the feathers 
of the belly. i have seen birds closely resembling them both 
from Bangkok and North Siam and comparison is required 
with the Hainan form, O. 6. wmbratilis, (Swinh.) and with that 
from Formosa and South China, O. b. glabripes (Swinh.). 
The present specimens have of course nothing to do 
with Otus sagittatus (Cass.) of which we have a specimen from 
Negri Sembilan. 
These owls were very common on Dayang Bunting and 
their hooting was heard throughout the night. They had 
probably come south on migration as O. B. lempiji also occurs 
in the same region.

This bird is typical O. 6. lempyi having a wing of 156 
mm.; another female from Bandon has the wing 152 anda 
male from Perlis about 150 mm. These last two were 
obtained in June and November respectively and probably 
represent the resident race. 
30. OTUS SCOPS MALAYANA (Hay). 
Scops malayana, Hay; Sharpe, tom. cit. p. 58; Robin- 
son and Kloss, p. 31; td. antea, vol. VI, p. 226 (1916). 
We obtained a pair on Langkawi in February, 1gog. 
Apparently not uncommon towards the north of the Peninsula 
but very rare in the south.
