(Photograph: Freeze-dried specimen lodged in the Durban Natural Science Museum, DNSM No. 36093. Diagnosis. Medium-sized shearwater with characteristic black-and- white plumage and distinctive, hooded appearance of head. Relatively long wings and tail, as well as bill, approaching P. puffinus in proportions, but in length distinctly smaller ( overall size c. 15% smaller), and in this respect closer to the assimilis/lherminieri complex (c. 5% larger). Similar bare part colouration to assimilis (see below), but differs in its larger size, longer wing, tail, and bill (see Appendix), and lack of predominantly white remiges below and variable whitish or pale extensions around the eye. Differs from Iherminieri in lacking a predominantly brown hue to the upperparts and undertail coverts; also lacks that species' well-developed nasal tubes and maxillary unguis, and has bluish-grey, not fleshy-pink, legs. In view of the considerable size difference, we consider that there is no further need to discuss P. puffinus and its closely related forms (auricularis, gavia, huttoni, nativitatis, opisthomelas, yelkouan). Description of type. Uniformly saturated blackish dorsally; black crown extends to just below the eye and is sharply demarcated. A small, indistinct diffuse area (greyish-white mottling) mainly on lower ear-coverts and indistinctly behind, also some whitish feathering on upper eye crescent and a conspicuous black loral patch. Within the otherwise uniformly black upperparts (head to rectrices, also entire upper wing), there are only some narrow, indistinct, diffuse (fresh) whitish tips to the greater coverts. Otherwise, the obvious demarcation. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration
