 TYPE. Mitchill did not designate a type specimen for this species.
As Notropis cornutus has often been confused with N. chrysocephalus,
particularly in areas where the two species occur sympatrically, I
feel that selection of a neotype is desirable. I therefore designate
as neotype of Cyprinus cornutus Mitchill (1817) an adult female
(UMMZ 174540), 69 mm SL, collected in the Wallkill River, 3 miles
southwest of New Paltz, Ulster County, New York, 2 June 1936 by
John R. Greeley and Reeve M. Bailey. Five other topotypes (UMMZ
114107) were collected with the neotype.
 The more important meristic counts for the neotype are: Anterior
dorso-lateral scales 20, circumferential scales 34, lateral-line scales 40,
caudal-peduncle scales 16, pectoral rays 16-16, anal rays 9.
 NOMENCLATURE. Notropis cornutus has been described as new
and named eleven times. Types are extant for only five of these nom-
inal species; I have examined them as follows:
Leuciscus frontalis Agassiz (MCZ 1751)-holotype
Leuciscus gracilis Agassiz (MCZ 1752)-two syntypes
Plargyrus bowmani Girard (ANSP 3236)-holotype
Hypsilepis cornutus cyaneus Cope (ANSP 3950-3959)-ten syntypes
Notropis universitatis Evermann and Cockerell (USNM 64151)-holo-
 type
 From 1885 to 1896 the specific name megalops was used in place
of cornutus. The change was instituted by Jordan on the grounds
that Mitchill's (1817: 289) brief diagnosis of Cyprinus cornutus, which
was published in July or August, 1817, did not constitute an adequate
description. Though Mitchill published a detailed description of the
species 6 months later, Rafinesque in the meantime had described the
same form as Cyprinus megalops. Jordan (in Jordan and Evermann,
1896b: 281) later reversed himself, and in 1916 the matter was finally
resolved by the International Commission of Zo6logical Nomenclature,
