The young male or the female is described by me as above, and only in the

 given in the description above referred to, but smaller than B. buccinator, Tem- 

 minck, which it resembles, though quite distinct.

 crested, the feathers of which are wide and rounded at the end. Head, breast, 

 sides and upper parts of body black, with a greenish lustre, rump, upper and under 

 tail coverts and abdomen, white. Primary quills black, secondaries entirely white, 

 tertiaries black tipped with white, under wing coverts white. Bill with its 

 upper segment distinct but small, under mandible rugose, (bill pale yellow in
