HYPOTHETICAL LIST [601] 



Slender-billed Fulmar: 



Priocella antarctica (Stephens) 



THIS is another one of Townsend's Pacific Ocean specimens that has been 

 credited to Oregon but that present-day ornithologists feel is not a satis- 

 factory record of North American occurrence. 



Giant Fulmar: 



Macronectes giganteus (Gmelin) 



THERE is a specimen of this bird in the National Museum collected by 

 Townsend (1839), labeled "Off the Columbia River." A bird so indefi- 

 nitely labeled is not regarded as a satisfactory North American record. 



Leach's Petrel: 



Oceanodroma leucorhoa leucorhoa (Vieillot) 



THIS PETREL is credited to Oregon on the strength of Woodcock's (1902.) 

 statements, based on information furnished by Bernard J. Bretherton and 

 Ellis F. Hadley, that it occurred in Yaquina Bay and at Tillamook. 

 There is no evidence to indicate that this northern race, as at present 

 understood, has occurred in Oregon, as our breeding birds are now refer- 

 able to 0. /. beali. 



Ashy Petrel: 



Oceanodroma homochroa (Coues) 



THIS SPECIES is credited to Oregon on the basis of Woodcock's (1902.) 

 statements recording it from Yaquina Bay on information furnished by 

 Bernard J. Bretherton. In view of the fact that the Forked-tailed Petrel, 

 which is a common breeding bird on the Oregon coast, is not mentioned 

 in Woodcock's list and that there are no other records of this southern 

 breeding bird this far north, we are placing the species in the hypothetical 

 list. 



Greater Snow Goose: 



Chen hyperborea atlantica Kennard 



THE GREATER SNOW GOOSE was reported by Bernard J. Bretherton as 

 common in the fall of 1899 on Yaquina Bay. The statement is recorded 

 by Woodcock (1902.). There is no other record of this eastern bird in 

 western Oregon, and it is undoubtedly a plain case of confusion between 

 the two forms of Snow Goose. The Lesser Snow Goose is even today a 

 common migrant in Oregon and occasionally congregates on the coastal 

 bays of the State.
