the proof-sheets. The manuscript of that part of the work from the Hyodontide to the 
end has been revised by the author in the fall of 1881, and thereby brought up to date. 
This will account for several discrepancies between the nomenclatnre as given in the 
lists of Ohio fishes (pp. 743-753), and that appearing in the text. 
It has been found impossible in the printing-office to which the State of Ohio entrusts 
its public printing, to send proof-sbeets to the authors for correction. I am, therefore, 
under great obligations to Dr. J. M. Wheaton for the care which he has taken in reading 
the proof-sheets in my stead. | 
Drawings of about one hundred species of Ohio fishes were prepared for this paper 
by Dr. E. R. Copeland, of Milwaukee, Wisconsin. The authorities in charge of the 
printing have, however, for some reason not seen fit to have them engraved.

CORRECTION TO MAMMALIA. 
Pages 118, 119—Dr. Frank W. Langdon in his paper on the ‘‘Mammalia of the 
Vicinity of Cincinnati,” says (Journ. Cin. Soc. Nat. Hist., Jan., 1881, p. 305, foot note). 
“Since the present article has been in type, I have received, through the kindness of 
Dr. J. M. Wheaton, of Columbus, Ohio, proof sheets of Dr. A. W. Brayton’s forthcoming 
Report on the Mammalia of Ohio (Ohio Geol. Survey, iv), in which I find myself given 
as authority for the occurrence of Spermophilus franklint in this State. This is an error 
for which I am personally and solely responsible, having misinterpreted Dr. Byrnes’ 
description of the animal at the time of sending the note to Dr. Brayton. Subsequently 
a more detailed description from Dz. Byrnes revealed the fact that the animal was S. 
tridecimlineatus, but by some oversight on my part, Dr. Brayton was never notified of the 
correction; his remarks on S. franklini, therefore, so far as they relate to Ohio, should 
be referred to S. tridecimlineatus.”
