White- Eyes, Sugar- Birds, and Tanagers. 29 



The other species of Euphonia are rarely imported, and need not 

 be noticed in this article. The same is true of Hypophcea chalybea, 

 the Lead-coloured Tanager. In the genus Tanagrella the beak of 

 the female is longer, more slender, and tapers more gradually than 

 in the male. 



Red-bellied Tanager (Tanagrella velia). 



The female, in addition to its different form of beak, is not quite 

 so brightly coloured as the male. 



Blue and Black Tanager (Tanagrella cyanomelama). 



The female resembles the male in colouring, so that the different 

 form of beak is important. 



Black-backed Tanager (Pipridea melanonota). 



The female differs greatly from the male, being dark brown above 

 with a tinge of blue on head and rump, instead of being violaceous 

 blue with blackish mantle, black wings and tail edged with blue ; 

 black forehead, lores, and sides of head, and clear ochreous 

 under parts. 



In the genus Calliste the beak does not differ uniformly in all the 

 species. C. /estiva and one or two others are rarely imported. 



The Superb Tanager (Calliste fastuosa). 



The beak of the male is broader and more regularly tapered, 

 when viewed from above, than that of the female ; the latter sex 

 has all the metallic green on head, neck, mantle, and wings of a 



MALE AND FEMALE SUPERB TANAGER.
