(syn. Phoenicurus Ϯ Plumbeous Water Redstart P. fuliginosus) Gr. ῥυαξ rhuax, ῥυακος rhuakos  torrent  < ῥεω rheō  to flow; ορνις ornis, ορνιθος ornithos  bird; "505  R. [RHYACORNIS] FULIGINOSA (Vigors).  ...  the wings are Ruticilline, and the general characters of the plumage of both sexes  ...  dissociate R. fuliginosa altogether forms [sic] Chimarrhornis. It appears to me, as it did to Dr. Jerdon, to form the type of a distinct subgenus which might be called Rhyacornis;* and which appears to me to have as good claims to separation as Adelura and Chimarrhornis. The characters are: Rhyacornis, subg. nov. Ruticillæ: Rostrum brevius et latius quam Ruticillæ, cauda magis rotundata. Fæmina a mari valde diversa, et rectricibus exterioribus basin versus albis.  ...  * From ρυαξ [sic], a stream and ορνις." (Blanford 1872).
