toes being very thickly feathered^ much more so than in any of the four 
species of Bubo here treated of. 
This Owl frequents deep forests^ and is said not to be so nocturnal in its 
habits as the other Horned Owls.

Description. — Male and female. The whole upper plumage dark brown, 
narrowly and closely barred with rufous ; quills brown_, barred with paler 
brown ; tail brown_, all but the central feathers barred with whitish on the 
basal half of the inner webs, and with fulvous-brown on the other parts ; 
the central feathers barred with fulvous-brown throughout ; ear-tufts 
dark brown, some of the feathers unmarked, others barred with white ; 
the whole lower plumage pale fulvous -white, closely barred across with 
irregular lines of brown. 
Feet clear yellow or chrome-yellow ; claws black or horny green, at base 
plumbeous; bill, cere and eyelids yellow, clear in the one specimen, 
chrome in the other ; irides dark brown. [Davison.) 
Length 18 inches, tail 6*5, wing 13*5, tarsus 3, bill from gape 1'8. The 
female is probably a little larger. 
Horsfield^s Horned Owl occurs in the extreme south of Tenasserim, 
where Mr. Davison procured one specimen. 
It extends down the Malay peninsula, and is found in Sumatra, Java 
and Borneo. Mr. Sharpe is of opinion that the Javan and Sumatran birds 
are identical. 
Nothing is recorded of the habits of this species. 
The Owls of the next genus are of small size, of remarkably beautiful 
plumage, and furnished with ear-tufts.
