(Muscicapidae; Ϯ European Robin E. rubecula) L. erithacus  unknown small winter bird, perhaps the European Robin, that metamorphosed in the summer to another (perhaps a redstart)  < Gr. εριθακος erithakos  unknown small bird, perhaps the European Robin, the Common Redstart, or the Black Redstart; "Rouge-gorges . . .  Erithacus." (Cuvier 1800); “This generic name is first met with on the second table at the end of Cuvier’s Leçons d’Anat. Comp. 1800. It is founded on “Rouge-gorges,” a group-name in the plural. There can be little doubt that Cuvier intended to use the name for the Robin, and in a previous work (‘Tableau elementaire,’ 1798) by the same author there is a reference to the “Rouge-gorge (Motacilla rubecula).” It would perhaps be difficult to justify the use of the name under the strict application of the international rules, but it has had such a long and widespread currency that the Committee have decided to retain it in preference to Dandalus of Boie [1826] ...  which has been used by Hartert and others of late years” (BOU 1915); "Erithacus Cuvier, 1800, Leçons Anat. Comp., 1, tab. 2. Type, by monotypy, Motacilla Rubecula Linnaeus." (Ripley in Peters 1964, X, 32).
