 not longer, as in Finicola. 



The genus Pyrrhula is an Old 

 World one ; extending across 

 from the Atlantic to the Pacific, 

 six or eight species or varieties 

 being recognized by naturalists. 

 All lia\'e the back ash-colored ; 

 the wings and tail, with top of 

 head, lustrous black ; the under 

 parts ash, generally with ver- Pwiixia cassini. 



milion on the cheeks and chin, sometimes extending over the whole under 

 sui'face ; tlie rump and crissum white : the females similar, but lacking the 

 vermilion. Its introduction into the North American fauna rests on the col- 

 lecting by the naturalists of the Eussian Telegraph Expedition in Alaska of 

 a specimen which — if a full-plumaged male, as stated — differs from all of 

 its congeners in the eutii'e absence of any vermilion tint.
