The genus Procellaria had been introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. The genus name is from the Latin procella meaning "storm" or "gale". The specific epithet conspicillata is from Latin conspicillum meaning "place to look from" and hence "spectacled". The word petrel is derived from St. Peter and the story of his walking on water. This is in reference to the petrel's habit of appearing to run on the water to take off. The species is monotypic: no subspecies are recognised. The genus Procellaria is a member of the family Procellariidae, and the order Procellariiformes. As a member of the Procellariiformes, they share certain identifying features. First, they have nasal passages…
