4.-DESCRIPTI0N OF A NEW SPECIES OF SHAD (ALOSA 

 ALABAMi:) FROM ALABAMA. 



By Barton Warren Evermann, Ph. D., 

 Ichthyologist of the United States Fish Commission. 



On April 10, 1896, the Un;ted States Fish Commission received from 

 Tuscaloosa, Ala., through the kindness of Mr. J. H. Fitts, of that city, 

 four specimens of shad which had been caught in the Black Warrior 

 Eiver. Upon comparing these specimens with numerous examples of 

 the common shad {Alosa sapidissima) from the Potomac and other shad 

 streams of the Atlantic coast, they were found to belong to an entirely 

 distinct and undescribed species. 



In view of the importance of this discovery, it is thought desirable 

 to publish this preliminary description in advance of a more complete 

 report upon the species.
