tlie Tubinares in the North Atlantic Islands. 493 



Group. Padre Schmitz included the species as breeding on 

 this group as early as 1893 on the authority of the owner of 

 the island, at that time Senhor Constantino de Noronha. 

 Mr. Jourdain has kindly called my attention to an apparently 

 very late date when eggs were obtained on the Salvage 

 Group, i. e. Oct. 23. Padre Schmitz recorded these eggs 

 in the 'Zeitschrift fiir Oologie,' xvii. p. 55. Tlie eggs were 

 brought to him on October 23 by fishermen, who had taken 

 them on the Salvages during the men's stay on that island. 

 As far as I can see^ these eggs may have been laid any time 

 within three months of the date upon which the boat 

 returned ! The men who make these expeditions to the 

 Salvage Group in search of Shearwaters always remain on 

 the island a considerable time. All the eggs were addled, 

 and I do not believe for a moment that they had been laid 

 in October. Oologists must be careful not to include this as 

 a date when fresh eggs of B. bulweri have been obtained. 



Breeding range in the Canary Islands. 



Bulwer's Petrel breeds commonly in this group, where it 

 arrives in the spring and departs again in the autumn. 

 Webb and Berthelot, and also Dr. Bolle, who quotes a con- 

 versation with Berthelot, say that it was very common in 

 Allegranza. During my last expedition to the outlying 

 islets of the eastern group, we did not meet Avith any 

 Bulweria bulweri on Allegranza in June ; however, on the 

 neighbouring island of Montaiia Clara it was exceedingly 

 numerous {vide ' Ibis,' 1914, pp. 80 & 268). 



In Tenerife it arrives in May, and on the 15th of that 

 month Meade-Waldo saw many off Garachico. Savile Beid 

 did not meet with any amongst the other Petrels and Shear- 

 waters which he noted between the 1st of February and the 

 middle of April. Bulwer's Petrel is entirely a night-flying 

 species during the breeding-season, and hence may easily 

 escape observation. It breeds on the Anaga Bocks oft' the 

 most northerly point of Tenerife in June, also at Victoria and 

 Santa Ursula on the main island. All the records of eggs 

 from Tenerife are in the month of June — the only juvenile
