(syn. Pteroglossus Ϯ Lettered Araçari P. inscriptus) Gr. γραμμα gramma, γραμματος grammatos  line, letter  < γραφω graphō  to write; ρυγχος rhunkhos  bill; "The birds comprising his [Bonaparte's] genus PIPERIVORUS I consider to belong to three distinct genera. The first - piperivorus - is a true Selenidera - the fourth, Bailloni - an Andigena; the second and third - viridis and inscriptus - might perhaps be separated; but in that case viridis would stand alone in one genus and inscriptus with Humboldti in another, for which the term GRAMMARHYNCHUS might be an appropriate appellation" (Gould 1854).
