Key to Scientific Names in Ornithology
(Tyrannidae; Ϯ Austral Negrito L. rufa) Prof. René-Primevère Lesson (1794-1849) French Navy surgeon-naturalist, explorer. "Genus, LESSONIA. ... Type. - Anthus sordidus, LESSON. Chili. Mus. Nost. ... It is unquestionably the fissirostral type of the Motacillinæ, and seems to render the rank of Seiurus, as a sub-genus of Accentor, no longer doubtful. By the kindness of M. Lesson, I am possessed of a specimen from the coast of Chili; and as I see no reason why botanists only should be commemorated by generic names, I trust I may be allowed to designate this new genus after the enterprising Zoologist by whom it was discovered" (Swainson 1832).
Synon. Auchmalea, Centrites, Centrophanes.
