me. to suppose that it does so very occasionally on the un- 

 inhabited islets or rocks. While staying on Montana Clara 

 from June 7-14, 1913, we procured a Storm-Petrel from 

 a hole in a cave on Jutie the 9th (Ibis, 1914, pp. 78, 263). 

 The bird was a male, and the testes were enormously 

 developed. Takinjij into consideration that eggs have been 

 found in the Madeira Group, it seems reasonable to suppose 

 this bird intended nesting on Montaria Clara. 



Webb and Berthelot write in 1841 : " It appears that this 

 species is found from time to time on the coasts of the 

 Canary Islands.^' Bolle in 1857 notes that " T. jptlagica 

 Vig. is the Storm-Petrel most frequently found in the 

 Canary Seas." Drouet mentions it in his list. Meade- 

 Waldo in 1893 found it always about the islands, but did 

 not discover it breeding. 



Cabrera possessed a specimen which had been caught 

 in Tenerife, and remarked that it occurred fairly frequently, 

 but was rare in certain seasons. 



Polatzek considered it a rare visitor to the Canaiies, but lie 

 does not appear to have spent much time at sea.
