MONOGRAPH OF THE PETRELS. 



birds breeding on the Rombos Islands in the Cape Verde Archipelago (Ibis, 1898, 

 pp. 96, 98). 



Mr. Nicoll, who accompanied the Earl of Crawford on the cruise of the 

 " Valhalla," saw large numbers of 0. castro before reaching Grand Canary ; and 

 for the first two days after leaving Funchal, on my way back to Cadiz, in 1871, these 

 birds were constantly seen flying round the ship. 



The range of this species is a very wide one, extending from the Atlantic to the 

 Pacific. It has been found in the neighbourhood of St. Helena, where a specimen was 

 obtained by Governor Janish, which is now in the British Museum, but as yet we have 

 no evidence of its occurrence in the Cape seas. 



That it occasionally wanders northward is proved by its capture at Littlestone, in 

 Kent, on the 5th December, 1895, as recorded by Mr. Howard Saunders (Bull. 

 B. 0. C, V., p. 37), the specimen being in Lieut. Boyd Alexander's collection; and 

 another has been recorded from Hythe in Kent on the 8th of November, 1906, by 

 Dr. N. F. Ticehurst (Bull. B. O. C, XIX., p. 10). Mr. Winge states that two specimens 

 were obtained in the succeeding year off the coast of Denmark, one on September 19th 

 on the lightship at Drogden, to the south of Copenhagen ; the second at 

 Kobbergrunden, in the Kattegat, on October 11th (Vid. Medd. Kjbbenh., 1897, p. 117). 



In the Pacific Ocean 0. castro has been found on Kauai, one of the Hawaiian 

 Islands, and Mr. Perkins has reason to believe that it will be discovered on others of 

 that group (Faun. Haw., Vol. L, pt. 4, p. 463). Mr. Bryan records it from French Frigate 

 Island (Key Birds Haw., p. 13). A specimen procured at sea by Mr. Beck, in Lat. 5° 

 30' N., Long. 102° W., is now in the Rothschild Museum at Tring. 



In the Galapagos, Dr. C. H. Townsend noted these birds off Wenman and 

 Albemarle Islands, and the Webster-Harris expedition met with them off Bindloe, 

 Barrington and Abingdon Islands (Rothschild and Hartert, Nov. Zool., VI., p. 198 ; 

 IX., pp. 415, 418). 



This Petrel doubtless occurs off the Pacific coast of Central America (Godman, 

 Biol. Centr.-Amer., Aves, III., p. 429), for a specimen was procured by Mr. Beck on the 

 12th of July, 1900, thirty-six miles north of San Benedicte, and is now in the 

 Rothschild Museum. It has also been recorded from the United States, a specimen 

 having been blown inland and captured at Monrovia, Indiana, and a second at 

 Washington, D.C., in August, 1893 (Butler, Auk, 1906, p. 274). 



No nesting-places of this Storm-Petrel have been discovered on the Pacific side of 

 North America, nor in the Hawaiian Islands, and, so far as I know, the species is only 

 known to breed on some of the Atlantic islands ; thus it has been found nesting 

 on Porto Santo, one of the Madeiran group, and on Lime Island, near Porto Santo 

 (Grant, Ibis, 1896, p. 53). From the last-named island eggs have been forwarded 

 to the British Museum by Padre Schmitz (cf. Oates, Cat. Eggs Brit. Mus., I., p. 148). 



Nesting-places of this species were also found on Praya Island in the Azores by Mr.
