ton days. There was a female there ou May 21. 1901. My only fall 

 ro'v'ords are October 22, 1S97, aucl November 4. 1907. This apparent 

 rarity is probably somewhat due to my short and infrequent studif s 

 along the lake. But the Loon is scarce at any time of year, and 

 dearly does not breed in Ohio now. 



1. (kiria arctica. — Black-throated Loon. 



The only record of this bird's occurrence within the region is that 

 gi^'en by Dr. J. M. Wheaton for Sandusky Bay in the fall of 1880 

 on the authority of Mr. H. E. Chubb, then of Cleveland, who mount- 

 ed the specimen.^ 



5. Uria lomvia. — Brunnich's Murre. 



During the visitation of 1890 four birds of this species were cap- 

 tured at Lorain, three in Sandusky Bay, and others reported from 

 Ottawa county during the last lialf of December. Professor E. L. 

 Moseley tells me that there were either five or seven in Sandusky 

 Bay in December, 1908, some of which were captured. It appears 

 that the birds do not survive long after reaching the waters of Lake 

 Erie. 



G. iStcrcorarius poDiarinns. — Pomarine Jfeger. 



Occurrences of this species are limited to a specimen in the col- 

 lection of Mr. A. Hengartner, of Lorain, where it was secured, and 

 the one reported in Cook's Birds of Alichigan by Professor E. L. 

 Moseley, for Sandusky, October, 1889. 



7. Stercorfiriiis parasiticus. — Parasitic Ja?ger. 



The records are as follows : Sandusky Bay. September 13 and 

 20, 1S89, and October G, 1895, E. L. Moseley. Near Sandusky, No- 

 vember, 1895. two specimens taken. F. M. Comstock.^ 



8. Lanis Iciicoptenis. — Iceland Gull. 



One specimen was taken at Lorain, December 22. 1888, and pre- 

 served by Mr. L. M. McCormick for the Oberlin College museum. If 

 it occurs with any regularity upon Lake Erie it has tlms far passed 

 unnoticed. 



9. Larus argeiitatiis. — Herring Gull. 



In the sense that it is present at all times of year it is a I'esident 

 if the proviso is added that it does not breed in the region. The 

 birds found in sunnner are clearly not breeding birds, although 

 some of them are in full adult plumage. During hard winters, when 

 the ice covers the lake extensively, the birds are less numerous and
