DESCRIPTION OF A NEW RED-WINGED BLACK- 

 BIRD FROM TEXAS. 



BY HARRY C. OBERHOLSER. 



Investigations of the birds of Texas revealed, many years 

 ago, an unrecognized subspecies of Agelaius phoeniceus 

 from the southern part of the State. Subsequent examin- 

 ation of material in the United States National Museum, 

 including the Biological Survey Collection, also in the 

 Academy of Natural Sciences of Philadelphia, the American 

 Museum of Natural History, and the private collections of 

 Mr. John E. Thayer, Mr. J. H. Fleming, Mr. William Brew- 

 ster, Dr. L. B. Bishop, and Dr. Jonathan Dwight, confirms 

 the distinctness of this form. Owing to an indefinite delay 

 in the appearance of our report on the birds of Texas, it 

 seems desirable now to publish a description of this new 

 red-wing. We accordingly propose to call it 



Agelaius phoeniceus megapotamus, subsp. nov, 

 Rio Grande Red-winged Blackbird. 



Chars, suhsp. — Similar to Agelaius phoeniceus richmondi 

 from southern Vera Cruz and Tabasco, Mexico, but larger; 

 female more grayish above and less ochraceous below. 



Description. — Type, adult female, No. 207912, U. S. Nat. 

 Museum ; Brownsville, Texas, February 17, 1911 ; A. K. 

 Fisher, original number 7093. General color of upper parts 

 dark fuscous ; broad medial crown streak pinkish bufif, 

 verging a little toward chamois; rest of the pileum, to- 

 gether with the cervix, much streaked with pale buff, dull 

 cinnamon, and clay color. Back and scapulars more 

 broadly and less numerously streaked with the same colors
