being entitled, ''Notes on the Winter Birds of Pea Island, 

 N. C. — Season 1906." Dr. Bishop's last visit to Pea Island 

 was Dec. 31- Jan. 11, and his observations at this time formed 

 an interesting basis of comparison with the two previous papers 

 he has presented to the Linnsean Society on the birds of Pea 

 Island. 



The second paper was entitled ''Notes on the Breeding Birds 

 of Turtle ^Mountain, North Dakota." Dr. Bishop has visited 

 this region four times, besides having correspondents in the 

 field. Especially interesting was the comparison of the birds 

 of the "mountains" — which are in reality only low rounded 

 hills — and the adjoining prairie. Although there is no dif- 

 ference in temperature in the two regions, practically no dif- 

 ference in altitude, and although both have woods, of the 144 

 nesting species only 54 are common to both regions, while 25 

 are peculiar to the "mountains" and 65 to the prairie.
