YELLOW-RUMPED BULL-FINCH. 



Cntliagra clirysopyga. 

 PLATE XVII. 



Olive-grey ; rump, front, eye-stripe, and under plumage, 

 yellow ; tail short, tipt with white. 



THE little bird we now distinguish, for the first 

 time "by the above name, is the only species we 

 ha-Fe yet received from Senegal belonging to the 

 family of Bull-finches ; this division of the finch 

 family, as a whole, is distinguished from all others 

 by a short and strong bill, curved above, and more 

 or -less swollen or inflated on the sides ; the under 

 mandible is generally stronger or thicker than the 

 upper, which, with the arched commissure, forcibly 

 reminds us of the bill of the parrots. Our own 

 beautiful native species exhibits these peculiarities 

 very strongly, and will give the student a very good 

 idea of the whole group. 



But as the Bull-finches pass insensibly into the 

 haw-finches, so there must be one part of the series 

 where the characters of both are so blended, that 

 it will be difficult to say, looking merely to a single 

 species, which are the most predominant ; whether, 

 in other words, our bird belongs to one or to the
