The alleged difference between the two forms consists in the 

 color of the crown patch, which in B. cinereicollis is yellow and 

 in B. conspicillatus orange. Both forms are obviously represented 

 in the present Santa Marta series, with also every stage of inter- 

 gradation between them. I have accordingly adopted the earlier 

 name cinereicollis in place of conspicillatus.
