With a considerable series of specimens Inifore 

 (H, we are unable to detect constant differences be- 

 tween Fulmars from the North Pacific Ocean and 



tiiose from the North Athmtic. In fact there is much more of individual than local variation in 

 this species, as regards size and proportions, while the color-variation is also chielly individual. 

 The few and slight dill'erences in coloration which appear to !« at all suggestive of local (lifler- 

 ciice in this respect are as follows : In all stages of jjlumage, specimens from the North Atlantic

 Not one of the three "adult" specimens shows any white on the wings. In all specimens from the 

 North Pacific the gray is much darker, of it moiv smoky hue ; some have no trace of du.-*ky in 

 liijnt of the eye, while others have a greater or less amount of white on the wing ; the type of
