Remark. 



This bird has so much in common with Procellaria oequinoctialis 

 that I am not sure whether it is a different species, or whether it l 

 also differs with reference to age; because it is generally known that 

 Lari [Gulls], with which this genus is most closely related, are, 

 when young, mostly of a brown color, which in the second year is 

 changed into white or gray. The single fact that seems of signifi- 

 cance to me and which might be the surest indication of a difference, 

 is that Air. Edward [Edwards], who has so accurately depicted 

 his birds, has in the other [the P. oequinoctialis], reproduced the 

 nares as if composed of two distinct cylinders [tubes], which is not 

 the case in this bird. 



Synonyma. He has not been correctly described by any author; 

 but occurs in several travellers' descriptions under the name of 

 Mallemuke. Bishop Pontoppidan, in his 'Ncrges Naturlige 

 Histori' [Natural History of Norway], mentions it only in Part II, 

 page 144, and states he has heard nothing else of the bird than that 

 Burgomaster Anderson referred to it in his accounts of Greenland 

 and Davis Strait [Anderson Island, 173, n. 30].
