 DISTRIBUTION. Restricted to tributaries of the lower Missouri
River in Missouri, to the Black, St. Francis, and Little river systems
in Missouri and Arkansas, and to a few small tributaries of the Mis-
sissippi River in eastern Missouri.
 The Bleeding Shiner is common in the lower (eastern) half of the
Osage system, and is generally distributed throughout the Gasconade
and Meramec drainages. It has crossed the lower Missouri in sev-
eral places and has become established in at least four small tribu-
taries flowing into this river from the north.
 The record of N. zonatus for eastern Tennessee (Evermann and
Hildebrand, 1916: 444) was based on specimens of N. ariommus.
Specimens recorded as N. zonatus by Cockerell (1908: 170) from
Boulder, Colorado, are N. cornutus.
