the basis of twelve specimens collected bj me in West Baton Rouge Par- 

 ish, the subspecies named above. This is in accordance with the opinion 

 expressed by Mr. Ridgwaj (U. S. Nat. Mus. Bull. No. 50, Part I, p. 641) : 

 "The bill is, in fact, decidedly larger in these Louisiana birds than in any 

 other specimens from the United States east of Arizona, and I have little 

 doubt that it will eventually become necessary to separate the Louisiana 

 bird as a different subspecies." The bird is an extreme Ij' abundant 

 resident. 



79. Zamelodia ludoviciana. Rose-breasted Grosbeak. — A rare 

 spring migrant; I saw one feeding on the fruit of the wild mulberry 

 {Morus rubra) on May 2, 1903. 



80. Guiraca caerulea. Blue Grosbeak. — Probably breeds rarely; it 

 is an uncommon spring migrant, and I saw none before May 2, which 

 date is abnormally late for its arrival. 



Si. Cyanospiza cyanea. Indigo Bunting. — An abundant spring 

 migrant, a much less common breeder. First seen April 14. 



82. Cyanospiza ciris. Painted Bunting. — Avery common breeder, 

 first seen on April 11. The conditions affecting this species and the pre- 

 ceding are reversed in East Baton Rouge Parish, where the Indigo Bunt- 

 ing is a much more conspicuous summer bird. 



83. Spiza americana. Dickcissel. — A rather common late spring 

 migrant, first seen April 30. It is uncommon as a breeder, and at least in 

 the territory between Lobdell and Port Allen, appears to be confined to 

 the small area occupied by Spizella pusilla. 



84. Piranga erythromelas. Scarlet Tanager. — A rather uncommon 

 spring migrant, present in 1903 from April 25 to May 9. 



85. Piranga rubra. Summer Tanager. — A common breeder ; first 

 seen April 11. 



86. Progne subis. Purple Martin. — An abundant breeder ; here, as 

 everywhere in Louisiana and Mississippi, a very early arrival. The first 

 — 'males, as usual — were seen Feb. 17. Young and old began to gather 

 into summer flocks about May 15. 



87. Hirundo erythrogaster. Barn Swallow. — Common in spring, 

 but does not remain to breed. First seen April 4 ; last seen May 27. 



88. Iridoprogne bicolor. Tree Swallow. — This species appears not 

 to be present here in winter, though a trip to New Orleans in late De- 

 cember revealed its presence there. I saw none here after the first of 

 December. The first spring migrants appeared on Feb. 27, and the last 

 left May 2. 



89. Stelgidopteryx serripennis. Rough-winged Swallow. — A spas- 

 modically abundant summer resident, always appearing to be in migra- 

 tion. First seen March 23, and present in rather small numbers until 

 late in May ; after that it was nearly absent until the middle of June, 

 when many began to pass westward ; and the majority of those seen after 

 this were moving westward up the river, in straggling flocks. 



90. Ampelis cedrorum. Cedar Waxwing. — Perhaps it would be
