● “I cannot see the slightest advantage to be gained by rejecting Bechstein’s name for the Chiffchaff on the ground that Boddaert’s Sylvia rufa may be the Whitethroat. It is obvious that Boddaert intended to designate a bird other than the Whitethroat by this name; and under no circumstances can the name of Phylloscopus rufa, Bechst., be confounded with any other bird than the one to which he applied it” (Seebohm 1881); “Bechstein’s name, used by both Seebohm and Saunders, and also in the 1^st edition [1883] of the List, really dates from his Gem. naturg. Deutsch. iv. 1795, p. 682, and is not an original description, but is founded on Gmelin’s Motacilla rufa. This is not a Phylloscopus, and the name cannot be used for the Chiffchaff” (BOU 1915) (syn. Phylloscopus collybita).
