Everywhere. Specimens taken in Lake Superior are largerthan brook 

 examples, often reaching a weight of four or five pounds. The speci- 

 mens found in the hike arc paler, duller, and more silvery in color than 

 those taken in the streams. 



10. Esoh lucius L. Pike. 

 Common. 



11. Perca lutea Rafinesqno. Yellow perch.

12. Stizostedion vitreum Mitchill. Wall-eyed pike.

13. Uranidea richardsoni Agassiz. Dogfish. 



Said to be common in the lake. One specimen secured. This is ev- 

 idently specifically identical with specimens from Southern Missouri and 

 the Ohio Valley. Compared with specimens from Southern Missouri 

 the example from Marquette is a little more slender, the coloration a 

 little less definite, being a little darker, with fainter cross-bnrs, and more 

 conspicuous dark punctulations. The vent is similar in position in all, 

 contrary to the statements of Girard, who finds the vent further back 

 in examples from Lake Superior (Original types of Cottus richardsoni).
