'•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 during a gale, its evolutions will compare in grace and spirit 

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



Manx's Shearwater {90. Puffinus vxiffinus) resembles the next in color, 

 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 

 or accidental occurrence on the North Atlantic coast.

 sides of the breast grayisli ; a patch on the flanks and under tail-coverts sooty 

 brownish black ; inner side of tarsi yellowish, outer brownish ; bill blackish. 

 L., 12-00; W., 8-00; Tar., 1-60; B., 1-20. 



Bange. — Warmer parts of the Atlantic, north rarely to Long Island ; breeds 

 in the Antilles and Bahamas, but not, so far as known, on our coasts.
