FISHES OF MINNESOTA 65 



the pectoral fins. Body elongate, more cylindrical than 8. vitreum; 

 head depressed, pointed; opercular spines few and not very promi- 

 nent. Head contained 3^ times in the length. Depth 4-^ to 6. Eye 

 5 in the head. Dorsal fin XI to XV-1, 17 to 19. Anal il, 11 or 12. 

 Scales 9-100 to 125-127. Pyloric ca^ca 4 to 7, unequal and shorter 

 than the stomach. Length 10 to 18 inches. The variety griseum 

 differs from the typical cavadensc, which it is supposed is found 

 only farther east, in having fewer and less developed opercular 

 spines and the head more naked. It seems that this species is 

 much less abundant than *§'• vitreum. 



Specimens were deseribed from Lake I*epin as Lneloptcrca pciri- 

 mis Estes (Hallock's Sportsman's Gazette, 822, 1877); a few speci- 

 mens have been taken in the Big Gull Lake and Mayo Creek, a tribu- 

 tary of the same (Nat. Hist. Surv., 1893). 



The representative of the genus Stizostedion needs some careful 

 study and the Nat. Hist. Surv. will be glad to get any reliable in- 

 formation on the subject.

Genus PERCINA Haldeman. 



Percina caprodes (Rafinesque). Log Perch. Rock-fish. Hog Molly. Hog-fish. 



The zebra-like markings on the sides, which are black stripes
