1002 ADDENDA AND ERRATA. 



the proof-sheets. The manuscript of that part of the work from the Hyodoniidce 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 nomenclature 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-sheets 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 paptir 

 by Dr. E. E. Copeland, of Milwaukee, Wisconsin. The authorities in charge "t 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 frankUni 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 Dr. Byrnes revealed the fact that the animal was S. 

 trideoimlineatus, 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. tridecmlineatm."
