many that have wandered up the Thames a long way 

 from the mouth of the river, even into the midst of 

 the metropolis.

LEVANTINE SHEARWATER. Pujffinus yelkouanus 

 (Acerbi). Length, 15-25 in.; bill, 1-9 in.; wing, 10 

 in. ; tarsus, 1*9 in. 



This is the Mediterranean representative of our 

 Manx Shearwater, and there is reason to suppose 

 that it may be met with annually on the south and 

 east coasts of England, though from its resemblance 

 to our bird it is probably often overlooked. An 

 example which I obtained at Torbay, Devon, in 

 August 1875, is in the British Museum, as also a 

 second specimen procured about the same time in 

 Plymouth Sound. Since then several have been 

 obtained on the Yorkshire coast, off Scarborough, in 

 Feb. 1899 and Oct. 1900. It is a larger bird than 

 the Manx Shearwater, browner in colour, and has 

 the flanks and under tail-coverts dusky-brown. 



GREATER SHEARWATER. Pujffinus major, Faber.^ 

 Length, 18 in.; bill, 2 in.; wing, 12-75 in.; tarsus, 

 2-25 in. 



An annual visitant in autumn to the coasts of 

 Devon and Cornwall, and to the Scilly Isles ; met 

 with accidentally, and at uncertain intervals, farther 

 eastward, as in Swanage Bay and Poole Harbour, 

 Dorsetshire ; Seaford, in Sussex ; Debden, Essex
