1538. Puffinus chlororhynchus.

The Green-billed Shearwater.

Puffinus chlororhynchus, Less. Traite, p. 613 (1831); Legge, Birds Ceyl. p. 1054; id. S. F. ix, p. 264; Oates, B. B. ii, p. 439 ; Salvin, Cat. B. M. xxv, p. 372. Puffinus sphenurus, Gould, A. M. N. H. xiii, p. 365 (1844). Puffinus ?, Legge, S. F. iii, p. 374; Hume, Cat. no. 976 ter.

Coloration. Dark smoke-brown, slightly paler and greyer beneath, especially on the throat, which has an ashy tinge.

Bill dusky greenish ; iris dusky ; legs and feet fleshy white (Legge).

Length 17 ; tail 5 ; wing 11 : tarsus 1.8 ; bill from gape 1.75. The median rectrices exceed the outer by about 1.5 inches.

Distribution. Indian Ocean, seas of Australia and New Zealand, and Southern Pacific. This Shearwater is common about the Seychelles, Rodriguez, and Mauritius, and has been found breeding at Round Island, near the latter. It has been obtained more than once on the coast of Ceylon, and is very probably, as Legge pointed out, the bird of which a specimen was once obtained at Madras by Jerdon, but lost before a complete description was taken (B. I. iii, p. 826). The Coloration of this was identical with that of P. chlororhynchus, but some of the measurements (length 18, wing 12 1/2, tail 5, bill at gape 1 3/4) were large and agreed better with those of Oestrelata macroptera, to which Jerdon noticed the resemblance. The latter is easily recognized by its tarsi not being compressed, and by its stouter bill; bill and feet black in colour.

I have seen off Bombay a dark-coloured Petrel that looked to me larger than P. persicus, but it was at a considerable distance.
