The final member of this subfamily to be noticed is Bulwer’s Petrel (Bulweria bulweri) of the temperate North Atlantic and Pacific oceans, which differs from the last by its longer, more graduated tail, less compressed bill, and smaller feet. It is only ten inches long and in color is uniform fuliginous dusky, lighter and more grayish brown beneath, while the wings are blackish. It breeds in the Canaries and Madeira, nesting in holes in rocks near the foot of the cliffs. Its cry is said to resemble that of a puppy.
