CHECK-LIST OF NORTH AMERICAN BIRDS. BY HARRY C. OBERHOLSER. This is the Fifth Annual List of Proposed A. O. U. Cbeck-List additions and changes in the names of North American birds. Like the First, Second, Third, and Fourth, 1 the present list com- prises only ornithological cases — i. e., such as require specimens or the identification of descriptions for their determination — and consists of additions, eliminations, rejections, and changes of names due to various causes. However, only changes known to be the result of revisionary work are included; therefore no men- tion is here made of changes involved in names in local lists or i For the four previous lists, see The Auk, XXXIII, October, 1916, pp. 425-431 ; XXXIV, April, 1917, pp. 198-205; XXXV, April, 1918, pp. 200-217; XXXVI. April, 1919, pp. 266-273. The A. O. U. Committee has not as yet acted on any of these cases.
