FISHES OF THE MISSOURI RIVER BASIN. 349 



swift, and water with a temperature of 79i°. The bottom was sandy, 

 the water clear, and there were no trees on the banks, only a few wil- 

 lows. We secured two species of minnows, one darter, and one sucker. 

 From a small pond near by we took a few catfish (Ameiurus melas). 



Norfolk Creel: flows into Elkhorn Eiver about 3 miles southeast of 

 Norfolk Junction, and near its mouth averages 35 feet wide and If feet 

 deep, but a few holes were as much as i> feet. The current was rather 

 sluggish and the water somewhat muddy. The banks were well 

 wooded in places with cottonwood, box-elder, willow, and ash. From 

 this stream we secured at least five species of minnows, two species of 

 darters, one species of black bass, two species of catfish, and a red- 

 horse sucker. 



Big lllue Hirer rises in southeastern Nebraska, flows south, and 

 empties into the Kansas River. We fished the Big Blue at Seward, 

 Nebr., where it was 30 feet wide, 2 to 4 feet deep, and very muddy. 

 From it we secured Lepomis humilis, Ameiurus melas, Notropis lutrensis, 

 and PimepJiales promelas. This stream was also examined at Crete in 

 1892, and by Mr. Butter at Crete in 1891. 



Lincoln Creel; a tributary of the Big Blue River, was 10 feet wide, 

 10 inches deep, had a current of 1 foot per second at York, was very 

 muddy, and registered a temperature of G8°. From it we took the fol- 

 owing species: Noturus fiavus, Pimephales promelas, Ameiurus melas, 

 Notropis lutrensis, and Notropis blennius. 



At Seward, Nebr., Lincoln Creek was 10 to 50 feet wide, 1 to 6 

 feet deep, and very muddy. We found but one species of fish here, 

 Notropis lutrensis. The place fished was just above a dam, conse- 

 quently the water was much deeper than at other places. 



Bearer Creel; a tributary of the Big Blue River, was fished at York, 

 Nebr. We found it a little larger than Lincoln Creek at the same 

 place, but the same kind of a stream, and with a temperature of 71°. 

 We took from it Ameiurus melas, Noturus fiavus, Notropis lutrensis, 

 Pimephales vromelas, Notropis blctmius, and Semotilus atromaculatus. 



HISTORICAL AND BIBLIOGRAPHICAL. 



In the following pages we give the bibliography of the ichthyology 

 of the Missouri River basin. We have meant to include all faunal lists 

 and such other papers as throw light upon the geographic distribution of 

 the species of fishes in the drainage basin of that river. The titles 

 are arranged in chronologic order, thus enabling one to see at a glance 

 the progress of ichthyological investigat ions in that region. Following 

 the title of each paper will be found a brief statement of the character 

 of the paper, and then a summary of its contents, including (1) the 

 page upon which the species is mentioned, (2) the name under which 

 recorded, (3) our identification of the nominal species, (1) the locality 

 from which the specimens were obtained, and (5) the name of the col-
