Mr. Swainson on several new groups in Ornithology. 347 



The well known Bishop Tanager will exhibit the above cha- 

 racters in full perfection. It is however necessary to observe, 

 that five very distinct species pass current among Ornithologists 

 undtr that name. Its natural situation is between Pt/ranga, and 

 the next group ; this latter transcession being apparently effected 

 by T. iiiuUicolor, Vieill.
