RARER BRITISH BIRDS.

Tlialassidroma 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.
