as may be supposed, less elevated than in the full- 

 grown bird. This species is supposed to be a 

 native of the Philippine isles. The bird in its 

 young or unadvanced state is mistakenly consider- 

 ed by BulTon as a distinct species, and described 

 under the name of Galao des Moluques. See the 

 Bontian Hornbill of the present work. 



VIOLACEOUS HORNBILL. 



Biiceros violaceus. B. nigro-violacens, abdomine caudoe lateribus 



remigumque apicihus albis, rostro albido, galea compressa antror- 



sum ohtusa macula nigra. 

 Violaceous-black Hornbill, with the abdomen and sides of the 



wing and tail-feathers white, whitish bill, and compressed casque 



obtuse in front and marked by a black spot,

This also is very much allied to the Unicorn 

 Hornbill, from which it differs in its somewhat 

 smaller size, which is intermediate between that of 

 the Unicorn and White-Beaked species : of the two 

 however it is, according to Levaillant, most allied 

 to the former, having the rostral casque flat on the 

 sides, not swelled as in the white-billed species: 

 from both it differs in the colour of its plumage, of 

 which the disposition is the same. When viewed 

 in a full light it is very richly glossed with violet, 

 green, and purple reflexions, though when viewed 

 in the shade it appears of a greenish black : the 

 lower part of the breast, the belly, tips of the wings.
