INTRODUCTION.

Precisely the same remark may be made with respect to his new genus RampuHoxanruus for Aaa
5 . C0-

ramphus prasinus and A. albivitta, inasmuch as they do not in my opinion offer sufficient generic differenc
es

to warrant their separation from the other birds with which I have associated them.
The birds comprising his genus Prperrvorus I consider to belong to three distinct genera. The frst
: 8
—piperivora—is a true Selenidera—the fourth, Bailloni—an Andigena; the second and third—viridi d
é —wiridis an
inscriptus—might perhaps be separated ; but in that case vrzdis would stand alone in one genus and
2 S an

inscriptus with Humboldti in another, for which the term Gram) 'NCHUS mig
’ MARHYNCHUS might be an appropriate

appellation.
