Adult. Similar in colour to the other species of Prion but with a 

 paler crown, hardly differing from the tint of the back; the spot 

 below the eye also paler and less conspicuous ; the terminal dark 

 band' of the tail wider : the bUl much narrower and more com- 

 pressed, though the unguis is as large as those of the other species ; 

 the sides of the mandible are nearly straight, and the lameUiB 

 feebly developed and quite invisible when the bill is closed.
