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 2, 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.
