FISHES OF THE MISSOURI RIVER BASIN. 415 



[Introduced species.] Salvelinus fontinali3 (Mitchill). Eastern Brook Trout. This 

 species has heen planted in a number of the streams of Nebraska, South 

 Dakota, and Wyoming. Specimens were obtained by us in Spearfish Creek 

 at Spearfish, Spring- Creek at Bazile Mills, Long Pine Creek at Long Pine, 

 Beaver Creek near Newcastle, and Big Goose Creek near Sheridan. In 

 Spring Creek we found the brook trout abundant and doing well. At throe 

 hauls with a short seine we caught at least 15 trout (which were returned 

 to the streams), mostly yearlings, though one was nearly a foot long. Mr. 

 George Brooks, of Bazile Mills, informs us that recently a trout weighing 2 

 pounds 9 ounces was caught in this little stream. The plant was made here 

 by the Nebraska rish commission some six or seven years ago, and has 

 proved very successful. The stream is so small, however, that the trout will 

 not, as a rule, attain a large size, and, unless fishing is carefully regulated, 

 the stream will become fished out. 



Long Pino Creek is a very good trout stream and we saw a number of very 

 fine trout there. This creek has become noted throughout Nebraska and 

 affords more and better trout fishing then any other stream in the State. 

 The creek is a large one, the water is excellent, and there is an abundant food 

 supply, consequently the trout grow to a large size and are of superior flavor. 

 Spearfish Creek is apparently the best trout stream in the Black Hills, sur- 

 passing in length and volume of water any of the other streams suitable for 

 trout in that region. Sufficient plants of trout have been made in the vicinity 

 of Spearfish to demonstrate the excellent character of the water. These 

 fish appear to be doing remarkably well, and the stream is able to support a 

 much larger supply than it now contains. Beaver Creek, near Newcastle, is 

 another excellent trout stream in which eastern brook trout and rainbow 

 trout have been planted. There are, of course, numerous other streams in 

 the Black Hills well suited to trout, but, so far as we were able to learn, no 

 plantings of importance have been made in them. 



94. Thymallus ontariensis montanus (Milner). Montana Grayling. Yellow Creek 



and Gallatin River and headwaters of Yellowstone River (as Thymallus 

 tricolor, Cope, 1872); tributary of Missouri River at Camp Baker, Mont, 

 (as T. montanus type, Milner, 1874) ; Madison River, Gallatin River, and 

 Horsethief Creek, Mont, (as T. sujnifer ontariensis, Jordan, 1891a); Red 

 Rock River, Red Rock, Mont. ; Beaverhead River, Dillon, Mont. ; junction 

 of Firehole and Gibbon rivers (Evermann, 1892) ; Missouri River, Craig, 

 Mont. (Eigenmann, 1894). 



95. Lucius lucius (Linnaeus). Pike: Northern Pickerel. St. Mary River (as Esox 



lucius, Jordan, 1878) ; Boyer River at Arion, Iowa (Meek, 1892) ; Floyd River 

 at Lemars and Sioux City; East Okoboji, West Okoboji, and Spirit lakes 

 (Meek, 1894); Dakota River at Jamestown (Woolman, 1896). This species 

 was found in Elkhorn River near Norfolk, and in Rock Creek near Mitchell, 

 where a single specimen a foot in length was secured. We were surprised 

 not to find pickerel in any of the other waters examined, as the sluggish 

 grassy streams and the small lakes would seem to be well suited to it. 

 Further collecting will probably show it to be more common in eastern 

 Nebraska and South Dakota than now appears. 



96. Fundulus diaphanus (Le Sueur). Kansas River (Graham, 1835). 



97. Fundulus zebrinus Jordan & Gilbert. Kansas River and branches (Graham, 



1885) ; Ellis, Kans. (Cragin, 1885a) ; Ellis, Ellis County, Kans. (Gilbert, 

 1885) ; north fork of Solomon River, Lenora, Kans. ; Saline River, Wakeeney, 

 Kans.; Smoky Hill River, Wallace, Kans. (Hay, 1887); Republican River, 

 Wano, Kans.; Logan, Kans. (Gilbert, 1889); Big Sioux River at Sioux City; 

 Silver Lake, Iowa (Meek, 1892); East Okoboji Lake (Meek, 1894). 



98. Fundulus catenatus (Storer). Jones Creek, Dixon, Mo.; Gasconade River, 



Arlington, Mo. ; Little Piney River at Nowburg and Arlington, Mo. (Meek, 

 1891).
