1539. Puffinus persicus.

The Persian Shearwater.

Puffinus persicus, Hume, S. F. i, p. 5 (1873): v, p, 293; id. Cat, no. 976 bis ; Blanf. Ibis, 1873, p. 215; Butler, S. F. v, p. 292; Barnes, Birds Bom. p. 421 ; id. Ibis, 1893, p. 175; Salvin, Cat. B. M. xxv, p. 381, pl. iv.

Coloration. Whole upper surface uniform blackish brown, the dark colour extending on the head to a little beneath the eye; feathers around eye whitish; lower surface pure white; flanks, axillaries, and under wing-coverts near edge of wing dark brown; remainder of wing-lining white.

Bill dusky brown, bluish at base, and on three-fourths of lower mandible ; irides brown ; legs and feet white, tinged with pink and lavender ; claws, margin of web, outer toe, and part of ridge of mid-toe black (Hume). The amount of black on the foot varies slightly.

Length 13; tail 2.8 (median feathers about .5 longer than outer) ; wing 7.9 ; tarsus 1.5 ; bill from gape 1.75.

Distribution. The Arabian Sea, from the neighbourhood of Bombay to Aden. Not rare off the Sind and Baluchistan coasts.

This bird is scarcely separable from the widely spread P. obscurus, of all tropical and subtropical oceans. It differs in having the axillaries dark brown instead of white or mottled, and is perhaps rather larger, but the difference is very slight. As Mr. Salvin has kept P. persicus distinct, I admit the species, but I am inclined to regard it as only a geographical race.
