In Bonaparte's character of the restricted genus Treron, he 

 says, "remigura tertia margine integro." This is an error, as 

 the third quill is quite as much sinuated or scooped out as in the 

 other members of the genus. He begins his description of this 

 species with the word " Minor," which might lead one to suppose 

 that it is a small species, whereas it is really one of the largest 

 of the genus, and only inferior to Butreron capellii, which pre- 

 cedes it in the ' Conspectus.'
