36 PEELIMINARY REPORT 



Jordan & Everinann's Fishes of North and Middle America, I, 269, 

 as being the representative of tliis species in Lake Superior. Speci- 

 mens collected in Lake Superior at Bayfield, Wisconsin, by Coll. 

 Milner were described by Dr. Jordan as Luwilus selene, Bull. U. S. 

 Nat. Mus., X, 60, 1877. Collections from the Lake Superior region 

 need careful study. 

 Notropis whipplii (Girard). Silver fin. 



Color silvery but rather dark, males bluish; scales edged with 

 dark; a black spot on the posterior portion of the dorsal fin; lower 

 parts of the body and fins in the males covered with a white pig- 

 ment in the breeding season, head and snout often covered with 

 tubercles. Bod}^ considerably^ compressed; back somewhat ele- 

 vated; arch of the back about equal to that of the belly; head short; 

 mouth small and oblique; lower jaw not projecting when closed. 

 Head 4^. Depth 4 in the adult, varying in the young, the latter 

 more slender. Eye 4^ in the head. Dorsal fin with 8 rays. Anal 

 3. Scales 5-38 to 40-3. Pharyngeal teeth 1, 4-4-1, their edges ser- 

 rate. Length 4 inches. Rather common in the state. Numerous 

 specimens have been taken from the lakes and streams of the Upper 

 Mississippi (Nat. Hist. Surv., 1892-3-5); from the Minnesota and 

 Blue Earth Rivers at Mankato (Cox, 1891-5); from the Chippewa 

 River at Montevideo (Woolman, 1892, Report U. S. Fish Comm., 

 1893). 

 Notropis cornutiis (Mitchill). Shiner. Red-fin. Dace. 



Scales so crowded that their exposed surfaces are very much 

 broader than long, especially on the sides; scales drop off easily; 

 lateral line decurved. Body varies considerably with age, the young 

 being more slender and less compressed than the adult; head rather 

 heavy and compressed, mouth and eyes moderate. Color dark 

 bluish above, very dark in spring males whose snouts are also cov- 

 ered with tubercles; sides and belly silvery, a dark stripe on the 

 back; spring males with the lower fins, sides and belly rosy. Head 

 4J in length. Eye 4 to 5 in the head. Dorsal with 8 rays. Anal 9. 

 Scales 6-41-0, averaging 23 in front of the dorsal, but may vary 

 from 15 to 40. Teeth 2, 4-4, 2. Length 5 to 8 inches. 



This is one of our most widely distributed species of fish. Speci- 

 mens have been taken wherever collections have been made, and it 

 will likely be found in every important lake and stream in the state. 

 Notropis cornutus frontalis (Agassiz). 



This variety differs from the typical N. cornutus in having a 

 larger head and fewer scales, 18, before the dorsal fin. It is doubt-
