in Indiana, and therefore in Ohio." In regard to this, Klippart 

 remarks, " Messrs. Jordan and Gilbert's Catalogue of the Fishes 

 of Indiana is here given, under the belief that the same species of 

 fishes found in Indiana south of the watershed may be found in 

 the waters of Ohio." The list contains many species not recorded 

 for Ohio after the lapse of a quarter of a century, and some that, 

 owing to peculiarities of distribution, probably never will be 

 taken. The second report contains descriptions of twenty-four 

 species " arranged from manuscript of Prof. D. S. Jordan, by his 

 assistant, Mr. Ernest Copeland," with plates of sixteen species. 

 As a whole the reports contain much that is good. 



By far the most important paper on Ohio fishes is that by 

 Prof. David Starr Jordan, published in the fourth volume of the 

 Report on the Geology of Ohio, entitled a " Report on the Pishes 

 of Ohio," and bearing date of December 10, 1878. Dr. Jordan 

 was at that time connected with Butler University, in Indiana, 

 and his services in the preparation of the report were engaged by 

 Prof. J. S. Newberry, the State Geologist of Ohio. This report 

 contains, besides the synonymy and many valuable notes in regard 

 to habits, careful descriptions of a hundred and sixty-five species 

 of fishes supposed to occur in Ohio. Of this number, nine have 

 .since proved to be redundant, while three others have been 

 reduced to varietal rank. Of the remaining number described, 

 more than fifty had not at that time been taken within the limits 

 of the state, but were included because their range was such as 

 made their occurrence within the state probable. Many of these 

 have since been noted, but at the time of publication of Jordan's 

 Report only about one hundred species had been recorded for the 

 state. 



Following Jordan's Report, in more recent years have 

 appeared a number of papers dealing with investigations more 

 local in their nature, but all contributing materially to our knowl- 

 edge of the occurrence and distribution of Ohio species. The 

 first of these of which I have any knowledge, appeared in the 

 Journal of the Cincinnati Society of Natural History, for July- 

 October, 1888, under the title, " Contributions to the Ichthyology 

 of Ohio, No. 1," by Dr. J. A. Henshall, and gave a list, with 

 occurrence notes, of seventy species noted in Hamilton County.
