Record of occurrences in the North Atlantic Islands. 

 The only example of the Great Shearwater which has been 

 actually taken in these seas was sent to Hartwig from 

 Madeira by Padre Schmitz. This bird was pronounced to 

 be P. cinereus by Hartwig in a letter sent to Schmitz, but 

 Dr. Reichenow informs me that it is really referable to 

 P. gravis. The specimen, which was recorded by Schmitz 

 on the authority of Hartwig as P. major, is, I am also in- 

 formed by Dr. Reichenow, not P. major but P. kuhli (probably 

 P. kuhli Jiavirostris) . It was obtained by a fisherman in the 

 first half of December 1892 on the east point of the Island 

 of Madeira, near Ponta S. Louren90. It probably more 

 often appears in these seas than is generally supposed, as 

 it must pass close to the Atlantic islands on its way north. 

 There should be no difficulty in recognising this Shearwater 

 at sea from the countless hundreds of P. k. flavirostris by 

 its distinct brown cap and by its much browner appearance. 

 Although not generally recognised, P. k. Jiavirostris is a 

 decidedlv larger bird.
