LAMPREYS AND FISHES OF INDIANA, 215 



County {1, '85, 410); Lawrence County {23, '84, 203); Ohio River 

 {10, '74, 223) ; Logansport; Wabash County (Hay, Uh-ey). Nelson 

 took specimens of the species in clear tributaries of Lake Michigan in the 

 vicinity of Chicago (7^, No. 1, 45). 



This species is said to live in the smaller and more rapid streams. At 

 Logansport I found several specimens in a small, rocky stream on July 2. 

 The brilliant colors of the males had already begun to fade. R. obkisus 

 has been distinguished from atronasus. The body is said to be somewhat 

 stouter, the head shorter, the barbel more distinct, and the coloration 

 somewhat different. The lateral band of the males is rosy. To this 

 doubtful species Dr. Jordan refers some specimens taken in Clear Creek, 

 Monroe County.* 



Genus HYBOPSIS Agassiz. 



Alimentary canal not more than twice the length of the body. Teeth 

 in the main row 4-4, with no grinding surface. Maxillary with a small 

 barbel. Premaxillaries protractile. Scales along the lateral line fewer 

 than sixty, 

 a. Mouth inferior, horizontal ; color silvery. 



b. Eye more than three in the head ; scales in lateral line about 

 thirty seven. hyodomus, p. 216. 



bb. Eye three and one-fourth ; scales about fifty-two. 



watauga, p. 216. 

 bbb. Eye larger, three or less in head. 



c. Scales along lateral line about forty-seven ; teeth 4-4. 



dissimilis, p. 217. 

 cc. Scales of lateral line thirty-eight to forty-two; teeth 1-4- 

 4-1, or 1-4-4-0. 

 d. Sides with a dusky baud. amblops, p. 217. 



dd. Sides without dusky band, bright silvery. 



dorerianus, p. 218. 

 aa. Mouth nearly terminal ; color grayish, little silvery. 



kentuckiensis, p. 218. 



'•■■ Rhinichthys oataeact.e (C.andV.). 



The range of this species of Rhinichthys is from Massachusetts to Montana, in clear, 

 cold streams. Dr. Jordan (;?, 8-57), states that it has been found in tributaries of Lake Erie, 

 and in the lake itself; and in his " Catalogue of the fishes of Illinois " {lu, No. 2), he says it 

 is found in clear tributaries of Lake Michigan, about Chicago. It may, therefore, be yet 

 found to be a resident of Indiana streams. The body is quite slender, the depth being con- 

 tained in the length five and one-half times. The eye is small, five times in head and two 

 times in the length of the snout. Scales 14-65-8. The color is dusky, and there is no dusky 

 lateral band.
