or rind of soft fruits. It is true that the Chaffinches have an almost 

 equally prominent tooth, but as all the Fringillidce possess a 

 remicle (i.e., a bastard primary shorter than its coverts), I do not 

 think the length of the primary-coverts in certain genera of Tanagers 

 is a sufficient reason for transferring them to the true Finches, as 

 has been done by Professor Ridgway. 



In most genera of Tanagers, the beak of the hen is more powerful 

 than that of the cock, and in many species it is longer in the hen ; 

 but these characters do not hold for all the genera or species, s< > 

 that it is necessary to specify the character of the beak in each 

 species.

All-green Tanager (Chlcro})honia viridis). 



The beak of the female, when seen in profile, is narrower than in 

 the male; it is also a duller bird, with the blue of the upper pa its 

 confined to the back of the neck and the rump. Why it is called 

 "all-green" I cannot imagine. 



The Violet Tanager (Euphonia violacea). 



In the female the beak is broader and longer than in the male ; 

 in colouring the sexes are wholly dissimilar ; the male blue and 

 saffron-yellow, the female olive-green, more yellowish on the 

 under parts.
