on a comparison of the two descriptions, and may be seen at a 

 glance on looking at the birds themselves. Latham's original 

 specimens of his "JJ'hite-breasted Barbei," under which name he 

 gave the first published description of this species, are still 

 extant in the Derby Museum at Liverpool. This bird extends 

 from Cayenne to the upper branches of the llio Negro, where 

 examples were collected by Mr. Wallace.

My thanks are due to Mr. Alfred Wallace for allowing me to 

 examine this and many other birds collected by him on the 

 Amazons and Rio Negro. As Dr. von Tschudi mentions the 

 present species as an inhabitant of north-east Peru, and 

 Mr. Wallace's specimens were from Para, we must conclude 

 that it inhabits the whole region of the upper and lower Amazon,

perhaps the commonest in collections. Prince Maximilian of
