Description. — Bill entirely black, strong, and rather dilated at 

 the base ; the rictus furnished with a few weak bristles, and the 

 margin of the upper mandible considerably sinuated. The crown 

 of the head is covered by a conspicuous crest of bright orange-red, 

 having the margins paler and more of a fulvous yellow. The ge- 

 neral colour of the plumage, both above and beneath, is brownish 

 black ; across the rump is a broad band of fulvous, and beneath 

 the chin is a short stripe of the same colour, extending half way 

 down the throat : part of the scapula, and the whole of the inner 

 wing-covers, are pure white ; wings brown ; tail black, and rather 

 lengthened ; tarsi brown. 



This species appears subject to some variation in the colour of 

 the crest, and in the extent of the fulvous stripe on the throat. 

 But as these varieties have not come under my own observation, 

 I must refer the reader to the admirable work of M. Desmarest on 

 this family. The above description has been taken from the male 

 bird as it usually occurs in Brazil : the female I have never seen. 

 I have frequently had occasion to observe, that where the same 

 species is found both in Cayenne and Brazil, the specimen 

 from the former country is invariably larger and more richly 

 coloured : may not this be attributed to the excessive heat and hu- 

 midity of that province, which may be supposed to affect the 

 animal productions no less than those of the vegetable world ?
