128 Bass, Pike, and Perch 



I have examined and compared specimens from 

 the St. Lawrence and Indian rivers, New York, 

 Lake Erie, the Wisconsin lakes, Lake Pepin, Chau- 

 tauqua and Conneaut lakes, Scioto and Mahoning 

 rivers, in Ohio, and have seen preserved heads of 

 large ones from Ohio, Kentucky, and Tennessee, 

 and found that they all agree so well in the num- 

 ber of branchiostegals, squamation of cheeks and 

 opercles, in dentition, fins, and in measurements, 

 that they must all be considered as one and the 

 same species. At the Chicago Columbian Expo- 

 sition there were some twenty very large speci- 

 mens of mounted skins from Canadian waters, in 

 the exhibit of the Ottawa Museum, which showed 

 well the variation in markings. Some still showed 

 the dark spots on a gray ground ; others were 

 more or less distinctly barred with broad or narrow 

 bands; others showed both bars and diffuse spots ; 

 and still others were of a uniform slate or gray- 

 ish coloration, without markings of any kind. In 

 the museum of the Cuvier Club, in Cincinnati, 

 there are quite a number of mounted skins of 

 mascalonge from the Wisconsin lakes, mostly 

 large ones, that also show all of the various 

 markimTS, as well as those of a uniform colora- 

 tion.
