We are again indebted to Dr. J. J. von Tscbudi for the discovery 

 of this fine species of Calliste, which is found along with other mem- 

 bers of the genus in the hot wood-region of Eastern Peru. Besides the 

 type-specimen (from which the present figure has been taken, and for 

 the loan of which I must again express my obligations to M. Coulon), 

 I have seen but one other example of this bird. This example, how- 

 ever, which is in the Belgian National Collection, was obtained by ex- 

 change from Neuchatel, and Tschudi therefore seems to be the only- 

 Naturalist who has met with this Tanager. 



Although allied to Lafresnaye's Calliste atricapilla, which it re- 

 sembles in the peculiar silvery-grey colouring of the back and black 

 cap, the present bird may be readily distinguished by the brownish- 

 golden throat and black breast, which render it easily recognizable 

 among the other members of the genus. 



Tschudi says that this Tanager, like other Callistce observed by 

 him, frequents the highest trees of the forest : he gives us no further 

 information concerning its habits.
