(syn. Semnornis Ϯ Toucan Barbet S. ramphastinus) Gr. myth. Pan, son of Mercury and Drope, the god of shepherds, hunters and rustics, who was of monstrous appearance and resided in the woods of Arcadia; "Tetragonops Jardine (Edinb. New Phil. Journ. II, No. 2, Oct. 1855, 404), as a genus of American Barbets is preoccupied by Tetragonops Gerstäcker (Monatsb. Akad. Berlin, Feb. or March, 1855, 85), and I will propose in its stead Pan, the name of a mythological god of the forests. The two known species will then be Pan rhamphastinus (Jardine), and Pan frantzii (Scl.)" (Richmond 1899).
