 NOMENCLATURE. Although adequately described by Fowler (1904:
245-246) the taxonomic relationships of Notropis pilsbryi have often
been misunderstood. This is evident from Fowler's original descrip-
tion, which compares the species with Notropis leuciodus, and also
from the identification by Forbes and Richardson (1920: 149) of the
hybrid combination Notropis cornutus (chrysocephalus) X Notropis
rubellus as "Notropis pilsbryi." Hubbs and Ortenburger (1929: 81-
82) and Hubbs and Brown (1929: 36) relegated pilsbryi to the syn-
onymy of N. zonatus, a decision with which Fowler concurred. Al-
though Jordan, Evermann and Clark (1930: 124) and Schrenkeisen
(1938: 123) list pilsbryi as a full species, their works were merely com-
pilations and were not based on original information. Hubbs and
Moore (1940) correctly demonstrated the distinctness of pilsbryi and
zonatus, and their findings have been followed since.
 DIAGNOSIS. A small species of Luxilus, rarely exceeding 85 mm
SL. Distinguished from other species of its subgenus (except N.
zonatus) by: A prominent dusky-black lateral stripe that encircles
snout and is present at all ages; a well-developed narrow secondary
lateral stripe situated parallel and dorsad to main lateral stripe; a jet-
black predorsal streak; few apical radii on scales; four or five prom-
inent scallops on posterior margin of those scales situated in or close
to lateral line; weakly developed nuptial tubercles on top of head
and back, present in one row along lower jaw, and absent from tip
of chin; body slender and terete at all sizes.
 Distinguished from N. zonatus by the following pigmentary char-
acters (see figure 5B and table 2): Lateral stripe on posterior part of
opercle not curved sharply upward, extending straight across and
bordering upper half of posterior margin; lateral dark stripe extend-
ing below lateral line for entire distance posterior to head; black
pigment in cleithral area extending ventrally only about halfway to
pectoral insertion; pigment in lateral stripe on caudal peduncle equally
distributed above and below lateral line; pigment around edges of
dorso-lateral scales not particularly dense, not forming parallel lines
