Hypothetical List. 



1. Colymbus holboellii (Reinh.). Holbcell's Grebe. 

 Although I have been unable to find any valid record of the 



occurrence of this boreal species in this state, it undoubtedly 

 occurs in severe winters, for Dr. Eugene Edmund Murphey pro- 

 cured two specimens at Augusta, Georgia, on February 13, 1904, 

 and Mr. Isaac F. Arnow shot a specimen at St. Mary's, Georgia, on 

 February 18, 1904. l These birds had to pass either along the 

 coast or the interior of the State in order to reach Georgia. 



This grebe breeds in the high boreal regions of North America. 

 One of the birds taken by Dr. Murphey is now in my collection. 



2. Qavia arcticus (Linn.). Black-throated Loon. 



Audubon says of this species in Birds of America: = 



I well recollect that while I was standing near the shore of a large inlet in South 

 Carolina, one of these birds, being shot while passing over my head at full speed, 

 did not, on account of the impetus, reach the ground until upwards of twenty 

 yards beyond me. 



Audubon was unquestionably mistaken in the identification of 

 the bird shot, as no additional examples have ever been taken in 

 this state, and the bird he refers to was evidently a young Loon 

 (G. immer), or a young Red-throated Loon (G. stellata). The 

 Black-throated Loon is a very rare bird even in the northern 

 United States, and I can find but one record for the Atlantic 

 states, namely — Long Island, New York, April 29, 1893, re- 

 corded in the Auk, 3 by Mr. William Dutcher. 



This Loon breeds in circumpolar regions. 



3. Fratercula arctica (Linn.). Puffin. 



In Audubon's Birds of America, 4 he states: 



The Sea Parrot, as this bird is usually called on the eastern coasts of the United 

 States, as well as by the fishermen of Newfoundland and Labrador, sometime! 

 proceeds as far south as the entrance of the river Savannah in Georgia, where I saw 

 a good number in the winter of 1831-32. It is by no means, however, common 

 with this species to extend its southward migrations so far, and I suspect it does 

 so only in very severe weather.
