jn 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 Fishes 
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.
