" The long, narrow wings are set stiffly at right angles with the 

 body, and the bird frequently glides half a mile at a time without 

 moving them perceptibly. It usually follows a direct course, and in- 

 variably skims close over the waves. I know of no other sea bird 

 whose movements are as easy and graceful. Indeed, at times, espe- 

 cially daring a gale, its evolutions will compare in grace and spirit 

 with those of the Mississippi or Swallow-tailed Kites " (Brewster).

 but is larger. W., 8-50-9-25 ; B., 1-35-1-40 ; depth of B. through base, •40--45 ; 

 Tar., 1-70-1-80 " (B., B., and E.). It is a European species of exceedingly rare
