● (Hydrobatidae; syn. Hydrobates † European Storm-petrel H. pelagicus) “IV. PROCELLARIA, Linn. emend. The genus of which the little pelagica L. is the type constitutes the fifth and the last one of this short-legged group of Procellarieæ. ... The genus Procellaria first appears in 1746, in the sixth edition of the Systemæ Naturæ, having as its type the P. pelagica, Linnæus. Throughout successive editions the same species is invariably made typical; as it also is in the Edition of Gmelin (1788), and in Latham’s Index Ornithologicus (1790). I am, therefore, quite at a loss to discover the grounds upon which modern ornithologists have been justifiable in assigning the name Procellaria to such a genus e. g. as that of which glacialis, or antarcticus, or Cooki, are respectively typical. ... If, however, with almost all ornithologists, we make a family Procellaridæ of Linnæus’ genus Procellaria, and proceed to separate the component genera according to the now generally received definition of a “genus;” then Procellaria must be restricted to pelagica and its congeners, and other names be found for the remaining generic groups; there are few points of synonymy, involving a Linnean name, more clearly demonstrated than this.” (Coues 1864); “Procellaria Linnaeus, 1758, Systema Naturae, ed. X, I, p. 131. Type, by subsequent designation (Coues, 1864, Proc. Acad. Nat. Sci. Philadelphia, XVI, p. 79), Procellaria pelagica Linnaeus, 1758.” (JAJ 2022).
