● “Owing to the discovery that Pallas’ Zoogr. Rosso-As., although dated on the title page 1811, was not published till 1827, Temminck’s name, dating from 1820, has priority over Sterna hybrida Pall.” (BOU 1915); “According to the Cat. Br. Mus. (Natural Hist.), p. 1505, the first two volumes of this classic were completed shortly after the author’s death [1811] ...The plates were published 1834-42” (Wood 1931) (syn. Chlidonias hybrida).
