DEFINITIONS

PUFFINUS
(Procellariidae; Ϯ Manx Shearwater P. puffinus)  English names Puffing (c. 1502) or Puffin (c. 1508), originally applied to the cured carcass of the fat nestling shearwater, a delicacy until the end of the 18th century (cf. Med. L. paphinus puffin; Late Med. L. puphinus puffin or shearwater). By confusion and association the name was gradually also applied to the Atlantic Puffin, becoming fixed on that species during the second half of the 19th century, but retained in ornithology as a generic name for the shearwaters (see Lockwood 1984, 121-122); "Genre du Puffin.  Genus Puffini" (Brisson 1760): based on "Puffinus" of Jonston 1650-1653, and Sibbald 1684, “Puffin of the Isle of Man” of Willughby 1676, and "Shear-Water" of Ray 1713; "Puffinus Brisson, Orn., 1, 1760, p. 56; 6, p. 130. Type, by tautonymy, Puffinus [puffinus] Brisson = Procellaria puffinus Brünnich." (Peters 1931, 1, 53).
Var. Pufflnus.
