PTERODROMA
(Procellariidae; Ϯ Great-winged Petrel P. macroptera) Gr. πτερον pteron  wing; -δρομος -dromos  -racer, -runner  < τρεχω trekhō  to run; the gadfly petrels were so named with reference to their fast weaving flight, as if pursued by horseflies; "1. FULMAREÆ.  ...  *4. Pterodroma, Bp.   14. fuliginosa, Banks. (grisea, Kuhl nec Gm.  lugens? Soland.  atlantica, Gould.)   15. macroptera, Smith.  (brevirostris, Less.)   16. aterrima, Verr.  (carbonaria? Solander.)" (Bonaparte 1856); "Pterodroma, Bp. (Thalassoica? p. Gr. - Procellaria, p. Hombr. et Jacq. - Ossifraga, p. Reich.) Rostrum brevissimum, curvum, valde compressum: cauda cuneata. Nigrae.  Cum genere BULWERIA Procellariearum analogiam praebent. Parvulae inter congeneres conveniunt quippe statura cum gigantibus illis propriae sectionis.    M. ant. pr. Afr.  3.    1. PROCELLARIA macroptera, Smith.   ...   2. PROCELLARIA FULIGINOSA, Banks, nec Lath.   ...   *3. PROCELLARIA aterrima, Verr." (Bonaparte 1857); "Pterodroma Bonaparte, Comp. Rend. Acad. Sci. Paris, 42, 1856, p. 768. Type, by subsequent designation, Procellaria macroptera A. Smith (Coues, Proc. Acad. Nat. Sci. Phila., 1866, p. 137)." (Peters 1931, I, 60).

● “In view of the stability shown by Arremonops conirostris conirostris through a wide area, the appearance of this form so near the type-locality of that race is surprising and inexplicable” (Chapman 1914) (subsp. Arremonops conirostris).
● “It certainly was unexpected to find such a striking and hitherto unknown species on Guadalcanar, and this and the discovery of other new forms on the island shows that the ornithological exploration of Guadalcanar has hitherto been very imperfect” (Hartert 1929) (Guadalcanaria).
● “et necata inexpectatum nobis gaudium dedit novae speciei, ante nunquam visae” (Forster 1844) (Pterodroma).
● "Named both for the unexpected nature of its distribution, being restricted to two provinces of Ghana, and the fact that there are no obvious geographic barriers that separate it from two other members of the genus" (Voelker et al. 2016) (subsp. Stiphrornis erythrothorax).
● “On examining a large series of birdskins collected in the northern parts of Celebes and presented to the Leyden Museum by S. C. I. W. van Musschenbroek, Esq., I was quite astonished to find, that there exists in the Minahassa, beside Strix [= Tyto ] Rosenbergii, another large species of Barn-owl, very different as well from Strix Rosenbergii as from all the other known species” (Schlegel 1879) (Tyto).
