Plate 56 (continued). 



Manx Shearwater. 



Dusky Shearwater 



(This figure is taken from Yarrell's description of an 

 egg sent to him with the bird by Mr. E. Vernon Harcourt, 

 who obtained it on the Deserta Islands. It represents the 

 minimum size of eggs of this species. An egg in the 

 Salmon collection (now in the Museum of the Linnean 

 Society), collected by Hurrell in the same locality, 

 measures I'd by 1*5 inch. The largest eggs of this 

 species from the Bahamas almost approach the small egg 

 of the Manx Shearwater figured on the same Plate).
