The following note is copied from Beebe (Our Search for a 

 Wilderness, p. 315): — "A splendid scarlet bird flew out and 

 alighted twenty yards away, again giving utterance to its char- 

 acteristic loud whistle. It was what I have christened the Black- 

 headed Scarlet Grosbeak, diff'ering from the description of this 

 species in being 8^ instead of 7| inches in length. It was scarlet 

 below, dull red above, with a scarlet necklace and a jet-black 

 head and throat. A yellowish female showed herself for only a 

 moment. The whistle was loud and penetrating, but sweet in 

 quality. 



" The nest, eggs, and young, as is the case with so many South 

 Americuu Birds, uro unknown."
