Genus 45. PuHeEnacopius, Cope. 
76. Phenacobius mirabilis, Grd. 
(Bul. Il, 61; Phenacobius scopiferus.) 
Occurs somewhat rarely throughout the State, from Galena to ex- 
treme Southern Illinois; almost invariably in small swift streams, 
or in the rapid, rocky parts of more sluggish creeks. 
Genus 46. Hricympa, Cope. 
77. Ericymba buccata, Cope. 
We have found this species only in the sandy stretches of the 
tributaries of the Wabash, where it is locally very abundant. 
Genus 47. Norropis, Raf. 
SHINERS. 
78. Notropis dinemus, Raf.—Emeraup Minnow. 
(Bul. II, 60; Notropis rubrifrons, Notropis atherinoides: Synop., 
2.02 and 2.03 ; Minnilus rubellus, Minnilus dinemus, Minnilus 
rubrifrons.) 
Excessively abundant; far commonest northward, but confined 
everywhere almost strictly to the larger lakes and rivers. Not a 
single specimen has occurred in our collections from the smaller 
lakes in Northeastern Illinois, while the waters of Lake Michigan, 
a few miles distant, were swarming with them along the’ shore. Not 
abundant in the Ohio and northern Mississippi, but rather common 
in the [linois. From the smaller tributaries of these streams we 
have not so much as one of this species. In the Wabash and. 
Saline Rivers, in Southern Illinois. 
79. Notropis macrolepidotus, Forbes. 
A very rare minnow, taken thus far only from the Illinois River. - 
80. Notropis atripes, Jordan.—Rep F 1. 
(Bul. Il, 59; Lythrurus atripes, Lythrurus diplemius: Synop.,- 
197; Minnilus atripes, Minnilus diplemius.) 
This species prefers especially small clear streams, in which it is 
occasionally abundant; but owing probably to the relative scarcity 
of such waters in Illinois, if occupies a subordinate place among 
our cyprinoids. It is commonest in the extremes of the State, oc 
curring but rarely throughout the central prairie region.
