11. Moxostoma macrolepidottim duquesnei (Le Sueur). Common White. Sucker. Common in Blue 
River at Crete, Nebr. A few specimens examined at Lemars, Iowa, from tbe Floyd River just 
below the dam. Also seen among “live bait” at Waterloo, Iowa. 
12. Placopliai-ynx carinatu.s Cope. Big-jaived Sucker. Very abundant in the Floyd River at Sioux 
City and Lemars. 
13. Campostoma anomalum (Rafiuesque). Stone-roller. A few were obtained in Floyd River at 
Sioux City, but it was found in considerable numbers in College Creek at Ames. Also seen 
among “live bait ” at Waterloo, Iowa. (Evermaun.) 
14. Hybognatlius iiuclialis Agassiz. Abundant in the Platte River at Fremont, less so in the Elk- 
horn at Fremont and Salt Creek at Lincoln. It was also found to he a common minnow in 
the Floyd River at Sioux City and Lemars, and in College Creek at Ames. In individuals 
2i\- inches long the intestine was 9 inches in total length. 
15. Pimephales promelas Ralinesque. Blue River, Crete, Nebr.; Platte River, Fremont, Nebr.; 
Elkhorn River, Fremont, Nebr.; Salt Creek, Lincoln, Nebr.; Floyd River, Sioux City and 
Lemars, Iowa; College Creek, Ames, Iowa; and Storm Lake, Iowa. Abundant in all suitable 
Xjlaces. 
16. Pimephales notatus (Ralinesque). Found at Fremont in the Elkhorn, at Crete in Blue River, at 
Sioux City and Lemars in the Floyd, and in College Creek at Ames. Common at Ames only. 
17. Cliola vigilax Baird & Girard. Seen in “live bait” box at Waterloo, Iowa. (E.) 
18. Notropis heterodon (Cope). Found among the weeds near the shore of Storm Lake and in 
College Creek at Ames. An examination of Prof. Hay’s type of Notropis germanus, which 
came from Smoky Hill River at Wallace, Ivans., shows that it belongs to this species. The 
sxjecimen is in very i>oor condition. 
19. Notropis caynga Meek. This minnow was found in limited numbers in Floyd River at Sioux 
City and Lemars, in Storm Lake with N. heterodon, and in College Creek at Ames. At Ames 
it is an abundant species. 
20. Notropis delicio.sus (Girard ) . Abundant in Platte and Elkhorn rivers at Fremont, Salt Creek at 
Lincoln, Blue River at Crete, and Floyd River at Sioux City and Lemars. Less common ak 
Crete than elsewhere. 
21. Notropis gilberti Jordan & Meek. A few individuals were found in the Floyd River at Sioux 
City and Ijemars 
22. Notropis topeka Gilbert. Found in Salt Creek at Lincoln, Blue River at Crete, and Floyd River 
at Sioux City and Lemars. It was found in greater numbers in Salt Creek than elsewhere. 
23. Notropis hudsonius (De Witt Clinton). A few specimens were obtained Ifom the Floyd River at 
Sioux City, while in Spirit and the two Okoboji lakes it is by far the most abundant minnow. 
At these lakes it is the iirincipal minnow used by local fisherman as live bait. 
24. Notropis lutreiisis Baird &. Girard. Platte and Elkhorn rivers at Fremont, Salt Creek at 
Lincoln, Blue River at Crete, and Floyd River at Sioux City and Lemars. The eastern limit 
of this widely distributed s])ecies seems to be in Central Iowa, it having been fomid bj^ me in 
the Des Moines River at Des Moines. Ravenna, Nebr., seems to be ne.ar the northwest limit 
of its range, as it was not found in any of the streams in southwestern South Dakota. To 
the southward it is an abundant fish in all suitable streams, as far at least as the Rio de los 
Conchos, in Chihuahua, iMexico, where it was obtained by Mr. A. J. Woolman. 
25. Notropis whipplei (Girard). A few specimens from Storm Lake. Noticed also in “ live bait” 
box at Waterloo, Iowa. (E.) 
26. Notropis megalops Rafiues<)ue. This sxiecies is abundant in College Creek, from which the col- 
lection contains 12 young sx)ecimeu.s. These do not differ from eastern specimens, excejit that 
the caudal peduncle is unusually long. This species is not common in Floyd River at Lemars 
and Sioux City, and is aqiparently more numerous in the Elkhorn River at Fremont, Nebr. 
No specimens were taken from other localities. 
27. Notropis jejunus Forbes. This sirecies was found in the Platte and Elkhorn rivers near 
Fremont, where it ax>iiears to be rather scarce.. 
28. Notropis dilectus (Girard). This species is also common in the Elkhorn River at Fremont, 
Nebr., and less common in Floyd River at Sioux City, Iowa. 
29. Pheiiacobius mirabilis (Girard). From Blue River at Crete ; apxrarently not common.
