102 Mr. D. A. Bannel-man on the [tbis, 



of fishei'men) as breeding on Montana Clara, one o£ the 

 eastern islets — a statement which I have proved to be quite 

 without foundation (Ibis, 1914, pp. .269, 270). 



Range. Leach's Fork-tailed Petrel inhabits the north 

 Pacific Ocean and the extreme north Atlantic and breeds 

 also on many of the islets off the Britisli Isles. In winter 

 it is a visitor to all the north Atlantic islands, and is thus 

 dealt with in detail \n my paper on the distribution of 

 Petrels and Shearwaters in the north Atlantic (Ibis, 1914, 

 pp. 450, 451). It has also occurred off Liberia, Sierra 

 Leone, and the Gold Coast on several occasions, and is said 

 to visit south Africa casually. Two other races have been 

 described from the Pacific [cf. Oberholser, Proc. U.S. Nat. 

 Mus. vol. liv. 1917, pp. 165-172).

The Madeiran Petrel is a Rare Visitor which has been re- 

 corded only once, M. J. Nicoll having observed large numbers 

 on 12 November, 1905, just before reaching Gran Canaria 

 during the cruise of the 'Valhalla' {cf. Godman, Mono- 

 graph of the Petrels, p. 16, et Nicoll, Ibis, 1906, p. 667). . 



Polatzek also mentions this species in his list of breeding 

 birds (Orn. Jahrb. 1909, p. 24), but solely on hearsay and 

 on no real evidence Avhatsoever. 



It is extraordinary that it has not been observed more 

 often, for it is a remarkable fact that it breeds in every other 

 group of the north Atlantic islands from the Azores to the 

 Cape Verde Archipelago {vide Ibis, 1914, pp. 451-460). 

 I do not believe it breeds anywhere in the Canary Archi- 

 pelago (Tbis, 1914, pp. 85, 269). Neither Webb and 

 Berthelot, BoUe, Godman, Savile Reid, Meade- Waldo, 

 von Thanner, nor myself have ever seen it. 



On the above evidence I cannot possibly include this 

 species with the other Petrels which I have termed Annual 

 Visitors. 



Range. The Madeiran Petrel breeds in the Azores, Madeira 

 group, Salvage Is., Cape Verde Is., and in St. Helena.
