mi. NE Baton Rouge, January 1, 1941. Burtville, December 8, 1939. Avery Island, May 3, 1939. Lake Charles, November 20, 1940. P. s. nevadensis (specimens by Burdick, Lowery, and Wallace)—Iowa Station, January 23 and 24, 1940. University, February 10 and March 10, 1940. University, December 7, 1941, and November 15, 1942. Cameron, December 6, 1942. There are at present no bona fide records of P. s. anthinus in Louisiana, since the one recorded example of that race (Oberholser, op. cit., 647) appears, on reëxamination, to be referable to savanna (fide J. L. Peters).

Ammodramus savannarum pratensis Vieillot, Eastern Grasshopper Sparrow

Eight specimens of the Grasshopper Sparrow taken recently in Louisiana are without exception referable to pratensis. Our one remaining specimen, a male collected at Pride on December 19, 1937, is an example of perpallidus as recorded by Oberholser (op. cit., 648). Although the present series is inadequate for determining the prevailing form in the state in the winter, it would appear that pratensis is more common, rather than perpallidus as indicated by Oberholser.

Chondestes grammacus strigatus Swainson, Western Lark Sparrow

Oberholser cited only one Louisiana record for this race. The following additional records are now available: a specimen was taken by Howell at Cameron on October 31, 1942, and one was obtained by me at University on April 13, 1945. The species is a transient in both localities. A supplementary winter record for the Lark Sparrow in Louisiana is that of an individual seen at Port Hudson on December 23, 1945, by Howell and Newman. The bird was shot, but unfortunately, it was not retrieved.

Junco hyemalis cismontanus Dwight, Cassiar Junco

The only specimen in our series of Slate-colored Juncos that is a clear-cut example of this race is a male taken by Ambrose Daigre at Catahoula Lake on November 29, 1939. A. H. Miller has confirmed the identification.

Calcarius lapponicus alascensis Ridgway, Alaska Longspur

Oberholser listed this species as a casual winter visitor in northern Louisiana, which was possibly no more than was indicated by records then available to him. Since 1938, however, the species has been observed in large flocks at various localities in the southern part of the state, notably in January, 1941, when the whole state was blanketed with snow. Nevertheless, snow is apparently not prerequisite to the appearance of the species this far south, for on January 1 and 3, 1943, a flock of approximately a thousand individuals was seen a few miles north of Jennings. Again, on February 14, 1943, about half of what may have been the original flock was observed there. In neither instance was there snow anywhere in Louisiana. Of the thirty specimens in the Louisiana State University Collection, eleven have been identified by Alexander Wetmore as somewhat intermediate between alascensis and lapponicus, but closer to the former. Only lapponicus has been previously recorded from Louisiana. The specimens of alascensis were taken at Baton Rouge on January 25 and 28, 1940; Cornor, January 27, 1940; Lottie, January 27, 1940; and 10 miles north of Jennings, January 1 and February 14, 1943 (Burdick, Campbell, Hewes, Lowery, and Wallace).
