Long: Kansas Birds 435 indebted to Dr. A. Wetmore, Dr. W. L. McAtee, Dr. E. R. Kalmbach, Dr. J. Grinnell and Dr. Louis B. Bishop for the use of specimens for comparative purposes. I have had the use of notes, and various field reports from observers in all parts of the state, which were invaluable in compiling data showing distribution and migration. For these I wish to thank Dr. Jean M. Linsdale, Mr. A. J. Kirn, Mr. Ralph J. Donahue, Miss Florence Barth, Mr. Wilfred Goodman, Mrs. O. B. Baldwin, Mr. Frank M. Alexander, Mr. G. A. Whitney, Mr. R. T. Shanstrum, Mr. P. B. Peabody, Mr. C. W. Hibbard, Dr. A. B. Leonard, Mr. J. D. Black, Dr. J. M. Porter and Dr. H. H. Lane. I have drawn freely from the literature, but too much space would be required to list all of the references cited in the original thesis. LIST OF SPECIES 1. Gavia immer immer (Brünnich). Common Loon. Rare, transient. An unsexed specimen in the Wetmore collection (No. 1,653) taken at McPherson, is the only one known from the state. 2. Gavia immer elasson Bishop. Lesser Loon. Uncommon, transient throughout the state. Specimens have been taken at Neosho Falls, Leaven- worth, Burlington, Douglas county, Wichita and Morton county. 3. Gavia stellata (Pontoppidan).

It occurs in the state between March and November. 9. Pelecanus erythrorhynchos Gmelin. White Pelican. Common migrant throughout the state. This large bird is most often seen on the larger rivers and lakes in the fall and spring. 10. Pelecanus occidentalis occidentalis Linnaeus. Eastern Brown Pelican. Accidental.
