Range in the Canary Islands. 



Mr. Nicoll states that he saw large numbers of 0. castro 

 on November 12 just before reaching Gran Canaria during 

 the cruise of the ' Valhalla/ but it is not mentioned by any- 

 one else, with the exception of Polatzek^ who gives it on 

 hearsay, with no real evidence whatsoever: I do not be- 

 lieve 0. castro ever occurs in the Canaries except as a rare 

 straggler. 



Breeding range in the Cape Verde Islands. 



Boyd Alexander found the Madeiran Fork-tailed Petrel 

 breeding in the Archipelago on both of his successful visits 

 to the Cape Verde Islands in 1897. In his first expedition, 

 which extended from February 10 until the end of May, 

 Oceanodroma castro was discovered first on the Rombos 

 Islands, a group of small uninhabited islets 5 miles to the 

 north of Brava. Apparently of this small group only one — 

 Cima Island — is inhabited by the Petrels, and there O. castro 

 was found breeding on March 16, ''many of which had 

 young, while most of the eggs were well incubated. ^^ 



Two months later, when exploring the island of Branca, 

 Boyd Alexander again came upon this Petrel breeding in 

 the first week of May. He notes that they had young, and 

 obtained five eggs of this species on the island. 



The second expedition was made in October of the same 

 year, and on this occasion two weeks, from the 7th to the 22nd 

 of October, were spent on the island of Raza, which lies next 

 to Branca. Two specimens of O. castro were obtained on 

 the 11th inst., but no mention is made of their breeding 

 during this month. The only known breeding-season 

 therefore in the Cape Verde Islands are the spring months, 

 March, April, and May. 



L. Fea, who spent a considerable time in the Cape Verde 

 Islands and has published the valuable results of his ex- 

 pedition in the Boll. Soc. Geog. Ital. ser. 3, 1898-9, has 

 given an account of this bird, which Count Salvador! 

 has published (c/. Ann. Mus. Civ. Genova, vol. xx, 1899, 

 pp. 301-2). Fea particularly mentions the island of
