THE FORKED-TAILED PETEEL. 



THALASSIDROMA LEACHII. 



General plumage like the last ; tail forked ; legs moderate ; membrane dusky. 

 Length seven and a quarter inches. Eggs unknown. 



THE Forked-tailed Petrel, a native of North America,

 have been driven inland by storms, and have fallen

 membranes black. Length scarcely six inches. Eggs white.

 the tempest, inspiring more terror than would be caused 

 even by the hurricane which they are supposed to com-

 stones. It is not, therefore, surprising that when the sea 

 is calm, and the sun bright, they lurk in their hiding-
