CONTRIBUTIONS TO THE ICHTHYOLOGY OF OHIO. 



No. 2. 



By Dr. James A. Henshall. 



In the Journal of the Society for July-October, 1888, pp. 76-80- 

 I have recorded a Hst of seventy species of fourteen famiHes of 

 fishes collected within the limits of Hamilton County, in April and 

 May, 1888. Since that time, in July, I visited Sandusky and Put- 

 in-Bay, where I was enabled to identify a number of species belong- 

 ing to the fauna of Lake Erie. 



In August, Hon. Nicholas Longworth of this city, in the cause 

 of science, kindly placed at my service his fine and commodious 

 steam-yacht "C. O.," with full crew of six men, for the purpose of 

 an exploration of the Ohio River and its tributaries. Owing to 

 this characteristic act of liberality and generosity on the part of 

 Judge Longworth, Prof. C. H. Gilbert and myself were enabled 

 to spend three weeks on the Ohio and its tributaries, between 

 Marietta and Cincinnati ; and although the river was at an unprece- 

 dented high stage of water for the season — from twenty to thirty 

 feet above low water-mark— covering the bars and backing up 

 the tributaries for miles, we succeeded in collecting most of the 

 species named in my former list, in extending the range of other 

 species, and in adding some not named in that list, and others not 

 heretofore taken in Ohio waters. 



During September and October I assisted Capt. J. W. Collins 

 and Dr. T. H. Bean, of the U. S. Fish Commission, in collecting 

 fishes from Ross Lake, Little Miami River and Sycamore Creek, 

 for stocking the aquaria of the Commission on exhibit at the Ohio 

 Valley Centennial Exposition, and I also had opportunities of 

 examining the aquaria of Mr. Hugo Mulertt at the same Exposi- 

 tion. I have also occisioiially inspected the fish mirkets of Cin- 

 cinnati for species from the Ohio River and Lake Erie. 



From these various sources I have been enabled to add forty 

 species and ten families of Ohio fishes not named in my first list — 

 a few of which are also to be added to the fauna of Hamiltoa 

 County.
