Four specimens out of a series of twenty-eight Blue-headed Vireos taken in Louisiana since 1938 are referable to this race. It has not been recorded previously from the state. The specimens consist of a male and a female collected at Bogalusa on February 9, 1939, a male taken at Tunica on March 30, 1939, and a female at Erwinville on March 11, 1941 (Lowery). #Helmitheros vermivorus# (Gmelin), Worm-eating Warbler Although there are no published nesting records of this species in Louisiana, it is now known to be a common summer resident in the beech-magnolia forests of the Bayou Sara-Tunica Hills section north of St. Francisville. Jas. Hy. Bruns has supplied me with copious data on the birds seen in the nesting season at Baines, and the two of us have spent a great deal of time searching for a nest, without success. However, Bruns obtained a juvenile female, just out of a nest, on June 28, 1942. #Seiurus aurocapillus furvior# Batchelder, Newfoundland Oven-bird #Seiurus aurocapillus cinereus# A. H. Miller, Gray Oven-bird Four specimens in our series of Oven-birds are identifiable without question as examples of _furvior_. Two were collected by me at University on September 15 and 25, 1940, and Tucker shot one there on September 27, 1942, and another at Cameron on April 29, 1945. There are also two specimens in the series referable to _cinereus_, as well as several that are intermediate between _cinereus_ and _S. a. aurocapillus_. Burdick shot one of the typical examples of _cinereus_ at University on September 24, 1942, and I shot the other at the same place on May 16, 1945. #Seiurus noveboracensis noveboracensis# (Gmelin), Northern Water-thrush #Seiurus noveboracensis limnaeus# McCabe and Miller, British Columbia Water-thrush A. H. Miller has recently examined our large series of migrant Water-thrushes and identified three as good examples of _limnaeus_, and six as _noveboracensis_, neither one of which has been recorded previously from the state. The specimens of _limnaeus_ were taken at or near University on October 2, 1942 (Howell), October 12, 1943, and May 11, 1945 (Burleigh). The specimens of _noveboracensis_ were collected at University on September 14, 1941 (Lowery); at Baines on September 4, 1943, August 20, 1944, and May 6, 1945 (Bruns); at New Orleans on October 20, 1941 (Burleigh); and at Cameron on April 26, 1942 (Lowery). #Geothlypis trichas occidentalis# Brewster, Western Yellow-throat I have found it impracticable to determine subspecifically every specimen in our series of 104 Yellow-throats from Louisiana. However, two female specimens taken by me, one at Cameron on December 4, 1938, and the other on False River at Lakeland on February 11, 1941, are without doubt representatives of the race now known as _occidentalis_, a subspecies not previously recorded from this state. Several additional specimens in the series are probably also of that race, but I am deferring, for the time, recording them as such.
