WHITE-THROATEl) GREY PETREL. 173 



in Norfolk in the spring of 1850. The specimen is in the 

 collection of Mr. Clough Newcome. 



Range outside the British Islands. The habitat of the species 

 is believed to be the islands of Haiti and Martinique, and 

 probably G.uadeloupe, in the West Indies, whence it occasion- 

 ally wanders to European waters. The specimens existing in 

 museums are very few. There is one in the Boulogne Museum, 

 supposed to have been shot near that town many years 

 ago. Another is in the Hungarian National Museum, believed 

 to have been killed near Zolinki, in North Hungary. Four 

 specimens are in Paris, three of which were sent by L'Herminier 

 from Guadeloupe, and the Leiden Museum possesses an 

 example, the history of which is unknown. A specimen was 

 obtained in Eastern Florida in 1846, and another was shot on 

 Long Island in July, 1850. This apparently completes the 

 record of known specimens in collections, besides the single 

 one from Haiti in the British Museum. 



Habits. Nothing has been recorded of the habits of this 

 Shearwater. 



Nest. The breeding-places will probably be found to be in 

 the high mountains of some of the tropical islands in the West 

 Indies, where it nests, in all probability, in the same manner as 

 the Blue Mountain Petrel of Jamaica, under boulders and 

 rocks in the mountains. 



Eggs. Unknown .
