Adult. Closely resembles B. albocristatus, but differs iu having 

 the cheeks, sides of the face, and greater part of the feathers oa 

 the throat and neck white witli black shafts ; the greater wing- 

 coverts and quills are not tipped with white or show only the 

 slightest traces of white at the extremities ; the basal half of the 

 upper mandible is covered by a large black and yellowish-white 

 scale. Total length 31-5 inches, wing 9-5, tail 17-4, tarsus 1-5.

 as in the adult.
