The bird to which M. Bourcier has given the specific name of cyanifrons requires separation from the last three species, as much or more than they do from their predecessors the Erythronotæ. M. Cabanis’s generic name of Hemithylaca having been applied to this group as a whole, subsequently to those of Saucerottia and Erythronota, I must either place his name in the rank of a synonym or adopt it for the present species, the only one of this particular form.
