Key to Scientific Names in Ornithology
(Rhinocryptidae; Ϯ Ash-coloured Tapaculo M. senilis) Gr. μυς mus, μυος muos mouse; ορνις ornis, ορνιθος ornithos bird; "The species of the genus Scytalopus are small, black, slaty or brownish wren-like birds of mouse-like habits ... exceedingly inconspicuous in life and all but invisible in death ... Myornis gen. nov. ... The species heretofore known as Scytalopus senilis (Lafr.) is obviously not congeneric with Scytalopus magellanicus (Gmel.), the type of the genus Scytalopus Gould, or with any other species of the genus known to me. Its laterally compressed and elevated, angular mesorhinium is shown in a slight degree by S. sylvestris and more pronouncedly by S. latebricola, but its rounded wings in connection with its lengthened tail is a feature not possessed by any species of Scytalopus and it is this combination of characters of bill, wings, and tail which appear to warrant its generic distinction" (Chapman 1915).
