y distributed and rather common below pool 14, but 
t has become quite rare and may be extirpated above

0 years old, for the upper pools (UMRCC 1953), pool 
6, and B-26 (Starrett & Barnickol unpublished) are 
wailable. 
*Notropis chrysocephalus (Rafinesque).—The strip- 
d shiner was present in one of our minnow-seine col- 
ections and in two of those made by Starrett & Bar- 
ickol (unpublished) below the mouth of the Missouri 
tiver; these fish probably came from nearby small tribu- 
aries. 
Notropis cornutus (Mitchill).—The common shiner 
s recorded from pools 1 (Underhill 1957), ee OR 
UMRCC 1953), and 10 (Becker 1966). It is report-

ool and in the headwaters of the river (Underhill 
i)

idely distributed above the mouth of the Missouri but 
usually represented by only a few specimens. Sup-

re available. 
Notropis emiliae (Hay) —The pugnose minnow is 
nerally distributed above pool 18 but is usually present 
ily in small numbers. Supplemental records are as

Nord 1967). 
Notropis hudsonius (Clinton).—The spottail shiner 
widely distributed and rather common above the 
outh of the Missouri River, and it is known from sev- 
al sites above pool 1 (Underhill 1957). Below the 
outh of the Missouri it is sporadic and less common. 
ipplemental records are available for pools 5 (UMRCC 
67), 6, and 7 (UMRCC 1953).

moderately common from pool 18 to the mouth of the 
nio River. 
*Notropis rubellus (Agassiz) —The rosyface shiner is 
orded from pools 6 and 11 (UMRCC 1953) but is 
obably accidental in the river. 
Notropis shumardi (Girard) —The silverband shiner 
relatively common near the mouth of the Ohio River, 
t this species becomes progressively less common up- 
eam. 
Notropis spilopterus (Cope).—The spotfin shiner is 
ly common from pool 18 upstream into the head- 
ters (Underhill 1957). The one record for the lower 
er is probably based on a straggler from a tributary. 
pplemental records are as follows: pools 4 and 6 
MRCC 1953). 
Notropis stramineus (Cope).—The sand shiner is 
lely distributed throughout most of the river, but it 
isually present in small numbers. Supplemental rec- 
S exist for pools 4 (UMRCC 1967) and 6-8 
MRCC 1953). 
Notropis texanus (Girard) .—The weed shiner is re- 
ded from pools 5-11 (UMRCC 1953) and 12 (Nord 
mut it is not common in the river, 
*Notropis venustus (Girard) .—The blacktail shiner 
7 
was taken in a recent minnow-seine collection at river 
mile 43, but the fish probably came from a tributary. 
Notropis volucellus (Cope).—The mimic shiner is 
common near the mouth of the Ohio River and is present 
in smaller numbers upstream to the mouth of the Mis- 
sour! River. It is also recorded from pools 3-11 
(UMRCC 1953), but it is apparently rare and may be 
extirpated in the upper pools, It is not known from the 
intermediate section of the river. 
Phenacobius mirabilis (Girard). —The suckermouth 
minnow is widely distributed but not common. Supple- 
mental records are available for pools 5, 8-10 (UMRCC

or specimens almost certainly were accidental in the 
river and probably came from a nearby small tributary. 
Pimephales notatus (Rafinesque).—The_ bluntnose 
minnow occurs throughout the river, but it is common 
only in the headwaters (Underhill 1957). Supplemental 
records are available for pools 2 (Underhill 1957), 3-6,
