through publication in appropriate journals. The Museum of Natural History at the University of Kansas solicits records and specimens which contribute to our knowledge of birds in Kansas. Files and collections at the Museum are available to any qualified person for study.

The last state-wide list of birds was prepared by W. S. Long (Trans. Kansas Acad. Sci., 43, 1940:433-456). This list and the unpublished thesis from which the list was abstracted have been of great value in preparing the present report. Many other persons have contributed and among these the names of the following must be mentioned because of the value of their contributions: Ivan L. Boyd, L. B. Carson, Arthur L. Goodrich, Jr., Richard Graber, Jean Graber, Harold C. Hedges, R. F. Miller, John M. Porter, and Marvin D. Schwilling.

Full standing in this check-list has been given only to species for which at least one specimen from Kansas has been examined by some qualified student. Exceptions to this admittedly arbitrary rule have been made in three cases, Trumpeter Swan, Turkey, and Carolina Paroquet, because there is no reason to doubt that each of these three species once occurred in Kansas and because opportunity for obtaining specimens from Kansas has been lost through disappearance of the species from the state. Other species reported from the state but not authenticated by specimens have been relegated to the Hypothetical List and their names and my remarks concerning these birds are enclosed in brackets. This procedure is intended to encourage collection of such species; it is not intended necessarily to indicate doubt of a record. In the case of a carefully identified but uncollected accidental, opportunity for obtaining a specimen may not exist again for a long period. This is unfortunate but emphasizes the need for judicious collecting.

A total of 375 species (or 459 species and subspecies), of which four are introduced, is included in this check-list. Additionally, 15 species are discussed in the Hypothetical List. An asterisk (*) preceding an account indicates positive evidence of breeding in Kansas of the species so marked. The total of species known to have bred at least once in the state is 173. Nomenclature in this list follows the American Ornithologists' Union "Check-List of North American Birds" (1931, 4th edition) and its supplements. Species on the Hypothetical List are included in their current taxonomic position in the main list.

Gavia immer (Brünnich). Common Loon. Uncommon transient throughout state.

Gavia stellata (Pontoppidan). Red-throated Loon. Rare transient. One specimen: female (Univ. Michigan Mus. Zool. 65778), Marais des Cygnes River, near Ottawa, Franklin County, October 20, 1925, Captain Joe R. White. Several sight records from Shawnee and Johnson counties within past 10 years.

Colymbus grisegena. Red-necked Grebe. Rare transient. One specimen: female (KU 7697), Kansas River east of Lawrence, Douglas County, October 29, 1910, Logan I. Evans.

Colymbus auritus. Horned Grebe. Rare transient. Two authentic specimens: Manhattan, Riley County, September 30, 1878; male (KU 27465), 2½ miles north of Lawrence, Douglas County, November 16, 1945, E. C. Olson and Ralph L. Montell. Several sight records, from eastern, central, and western Kansas.

Colymbus caspicus. Eared Grebe. Regular transient throughout state; more common than Horned Grebe.

Aechmophorus occidentalis (Lawrence). Western Grebe. Rare transient, perhaps more common in west but status poorly
