 Under  this  name  Mr.  Ridgway  in  1881  described  the  
 Forked-tailed  Petrel of  the  Sandwich  Islands ;  he  afterwards  
 traced  it  to  the  Galapagos.  Still  more  recently  
 it  has  been  recognized  as  an  inhabitant of  St.  Helena  
 and  the  Salvage  Islands  in  the  Atlantic.  It  has  now  
 found a  place  in  our  fauna, a  bird  undoubtedly of  this  
 species  having  been  picked  up  dead  on  the  beach  at  
 Littlestone, in  Kent, on  5th December,  1895, and  passed  
 into  the  collection of  Mr.  Boyd  Alexander before  it was  
 skinned.  It  has also  occurred in  North  America.
