The 1)111 is sleiuler and atteiinaterl, very little deeurved. imic'li less so than 

 in /. cacaUatt's, slenderer and a liltlc more deeurved than in /. holthnore. 

 The tail is moderately graduated, the outer feather .45 of an inch less than 

 the niiddl-^. 



In this species the black feathers of the neck, except helow, have a suh- 

 terninal har of yellow ; elsewhere it is wantini;. The hlack of the breast 

 conies a little posterior to the anterior extr»'niity of the folded wini;-. The 

 l)osterinr feathers in the yellow ]>ateh on the shoulders are tin.ne^l with white. 

 The white in the bar across the ends of the greater coverts is confined 

 mainly to the terminal quarter of an inch of the outer web. In the full 

 jdumage, there is only a iaint trace of white on the edg:es of the ])riniaries. 

 The yellow of the base of the tail only extends on the middle feather as far 

 as the end of the upper tnil-coverts ; on the three outer, it reaches to within 

 an inch and a quarter of the end of the tail. 



An immature male has the yellow more tinj^ed with _«:reen, the Ithick feath- 

 ers of the head and l)ack olivaceous with a black s])ot. 



Specimens vary much in size ; the more nortln'rn beinn the laruer.
