 7-10 December, 1916 [Nos. 3602, 3016. 

 "Iris brown, bill pale greenish horn, tarsi white, 

 tinged with greyish pink, claws pale horn." 



After comparison with a 1 onsiderable 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. lempiji (HorsD that it is impossible to identify them 

 with that form whose wing never exceeds 157 mm. The two 

 specimens differ widely inter se, one having the forehead largelv 

 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 

 w-ith the Hainan form. 0. b. umbratilis, (Swinh.) and with that 

 from Formosa and South China, 0. 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 0. B. lempiji also occurs 

 in the same region.

This bud is typical 0. b. lempiji having a wing of 156 

 mm.; another female from Bandon has the wing 152 and a 

 male from Perlis about 150 mm. These last two were 

 obtained in June and November respectively and probablj 

 represent the resident race. 



30. Otus scops malayana (Hay).

We obtained a pair on' Langkawi in February, 1909. 

 Apparently not uncommon towards the north of the Peninsula 

 but very rare in the south.
