MONOGRAPH OF THE PETRELS. 



bill yellowish, passing into dusky at tip ; wing, 15 inches ; tarsus, 2.35 ; middle toe 

 and claw, 3.15." 



In the " Checklist of North American Birds " (2nd ed., p. 33) the Calif ornian 

 specimen referred to by Lawrence in the " Birds of North America " (1858, p. 835) is 

 recorded as Puffinus cinereus, and not P. gelidus. 



Professor Giglioli, who has written an instructive memoir on the geographical 

 distribution of Petrels, the result of personal observation during the voyage of the 

 " Magenta," states that, in his opinion, examples of Priofinus from the Pacific have 

 a somewhat larger and stouter bill, both mandibles verging on bluish-grey, with the 

 apex light horn-colour, and with a black groove. The upper-parts of the head, and 

 the under tail-coverts, are more dusky. 



Priofinus cinereus is a bird of the Southern Oceans, where it enjoys a very widely 

 extended range. Most of the specimens examined by me have been from the Cape 

 seas ; others were procured by Mr. T. Parkin in Lat. 39° 51' S., Long. 8° 49' E. (Bull. 

 B. 0. ft, X., p. cvi.). The late Nikolai Hanson met with the species in Lat. 39° 55' and 

 42° 23' S. ; Long. 3° 16' and 20° 32' E. ; in October, 1898 (Sharpe, Rep. Voy. " Southern 

 Cross," Aves, p. 142), and the Earl of Crawford obtained it in Lat. 35° 20' S. ; 

 Long. 9° 43' E. 



A single example was also procured by the Scottish Antarctic Expedition near the 

 island of Ascension, which is at present the most northerly occurrence recorded. 

 Further specimens were observed by the naturalists on board the " Scotia " between 

 Lat. 60° S. and Gough Island (Eagle Clarke, Ibis, 1907, p. 329), by Dr. A. B. Meyer in 

 Lat. 38° S., Long. 12° W., not far from Tristan da Cunha (Salvin, Cat. Birds Brit. 

 Mus., XXV., p. 391), and by the late Commander Sperling in the Mozambique Channel 

 {Ibis, 1868, p. 293). 



The species was also obtained by Macgillivray during the voyage of the 

 " Rattlesnake " in the South Indian Ocean in Lat. 37° S., Long. 53 1 ° E., in April, 1847 ; 

 and again in Lat. 35|° S., Long. 85° E., on the 2nd of July in the same year (Salvin, 

 Cat. Birds Brit. Mus., XXV., p. 391). 



Professor Giglioli records P. cinereus during the voyage of the " Magenta " to the 

 north-east of Amsterdam Island, between Lat. 42° 51' S., Long. 10° 15' E., and Lat. 27° 

 49' S., Long. 96° 32' E., on the voyage from Batavia to Melbourne, and in Bass's Straits ; 

 also in the Bay of Penas, in Western Patagonia, as well as in the Straits of Magellan. 

 Gould mentions the bird between Lat. 30° and 55° S., Long. 36° 30' to 154° W. 

 Hutton reports it as plentiful off the coast of New Zealand, but Buller never saw an 

 example, and none of the museums in the island possessed specimens, when he wrote. 

 The late Captain Fairchild procured this Petrel between Wellington and the Chatham 

 Islands (Buller, Suppl. Birds N.Z., I., p. 106). Layard mentions it off New Caledonia, 

 and on the homeward voyage of the " Discovery " it was seen in Lat. 58° S., Long. 

 160° E. Darwin obtained P. cinereus near Tierra del Fuego, Chiloe, Callao Bay in
