34 PEELIMINAEY EEPOET 



Notropis anogenus Foibes. 



Lateral line usually complete; body rather stout; mouth very 

 small and very oblique; lower jaw not projecting; snout very 

 blunt, shorter than the eye. Color dark; a dark band on the sides, 

 which passes through the eye ; a small dark spot at the base of the 

 caudal fin; a row of black dots along the upper side of the lateral 

 line; chin black. Head contained 4^ times in the length of the 

 body. Depth 4 2-5. Eye SJ. Dorsal fin with 8 raya. Anal 7. 

 Lateral line with 34 to 37 scales, 13 scales before the dorsal fin. 

 Teeth 4-4. A fish similar to the N. heterodon. Probably rare in 

 this state. The only record of its occurrence, so far, is given in Dr. 

 Seth E. Meek's Keport of the Fishes of Iowa (Bull. U. S. Fish 

 Comm., X, 1890, p. 232), where it is listed from the Cedar River at 

 Austin, Minn., as rare. 



Wotropis cayuga Meek. 



Body slender, a black stripe around the snout, through the eye, 

 along the sides of the body and ending in a small dark caudal spot; 

 the stripe on the sides generally broken at regular intervals, making 

 it appear as so many dark spots ; chin not black. Eye large, about 

 equal to the snout; jaws equal; lateral line absent on some scales. 

 Head 4 1-6. Depth 4^. Eye 3|. Thirty-six scales in the lateral 

 line, 14 before the dorsal. Teeth 4-4. Length 2^ inches. 



Very common in the southern part of the state, not so common 

 in the northern portion. It has been recorded from the majority 

 of the lakes and streams of the Upper Mississippi (Nat. Hist. Surv., 

 1892-3-5) ; streams and lakes in the vicinity of Mankato and south- 

 west (Cox, 1891-5). 



Xotropis hcterodoD (Cope). 



The chin black; a black dorsal band; sides with a dark band; 

 general color olivaceous. Body rather stout, back a little elevated; 

 head and snout pointed; mouth oblique, the lower jaw projecting. 

 Head 4. Depth 4. Eye 3. Dorsal with 8 rays. Anal 8. Scales 

 5-36-3; lateral line usually not complete; 13 scales before the dorsal 

 fin. Teeth 4-4, occasionally 2, 4-4,. 2. Length '2^ inches. 



This fish is not believed to be common in Minnesota. It is re- 

 ported from the Pomme de Terre River at Appleton (Woolman, 

 1892, Report, U. S. Fish Comm., 1893), but its resemblance to some of 

 the other CyprinidBe, notably Pimephales promelas, makes its iden- 

 tification difficult. Further collections are necessary to ascertain 

 its distribution.
