In view of the several examples now at our service it is almost 

 necessary to recast the generic diagnosis formerly given. 



Generic Characters — 



Beak much shorter than the head, shallow, but deeper than 

 ^road, with a more or less feeble maxillary notch, culmen regularly 

 arched from the nostrils forward, over the nostrils nearly straight, 

 compressed ; nostrils oval, sunken, subbasal, entirely hidden by plumes, 

 with very few and feeble bristles : rictal bristles few and feeble. 

 Wing rather short and rounded — fourth quill the longest, third and 

 fifth nearly equal. Tail strongly emarginate in the male, the feathers 

 subspinose at the tip. Tarsi moderate, shields nearly confluent ; 

 outer toe longer than the inner, middle toe shorter than the tarsus. 



Specific Characters — 



Adult male. — General colour of upper surface, wing, face, ear- 

 coverts and chin, bright olive strongly washed with yellow. A 

 short crest on the vertex, a broad nuchal collar and all the under 

 surface (but the chin) bright golden yellow, less intense on the 

 breast and ablomen ; upper surface of primaries passing into olive 

 brown near the tips, ba-al portion of inner webs broadly edged with 

 citron vellow to a length increasing gradually proximad. Under 

 wing coverts, under side of shafts of primaries and their inner edges 

 co-extensively with the upper surface, golden yellow. Two central 

 tail feathers brown above, faintly washed with yellow : sub-central 

 feathers with the terminal half of the outer and terminal third of 

 the inner web brown, the next largely and the following slightly- 

 brown tipped : for the rest all the feathers bright golden yellow : 

 under surface of shafts yellow. Legs, feet, and bill dark brown, 

 paler on basal portion of under mandible. Total length 235 m.m. 

 culmen 15, gape 22, wing 125, tail 120, tarsus 30. 



Adult female. — The sombre colours of the young female become 

 much brighter in the adult. The whole of the upper surface passes 

 gradually into a rich olive brown, the under surface of the tail into 

 a shining yellowish olive, the pale yellow of the lower surface of the 

 edges of the primaries into golden yellow, across the lower throat is
