RARER BRITISH BIRDS. 101 



Thalassidroma Bullockii. FLEM. (Fork-tailed Petrel.) 



A specimen of this bird is in our collection, obtained near 

 Shrewsbury. 



Hybrid Bird. 



Since our account of the hybrid bird between Cock Pheasant 

 and Grey Hen, contained in the preface, went to press, we have 

 been informed, by Joseph Sabine, Esq. that a bird under similar 

 circumstances has been killed in Cornwall. We have also had 

 an opportunity of inspecting one killed near Corwen, and now 

 in the collection of Sir Rowland Hill, Bart.
