 TYPE. Notropis megalops albeolus was described on the basis of
specimens David Starr Jordan collected in the Roanoke River at
Roanoke, Virginia, 31 July-2 August 1888. Although no types were
designated, the United States National Museum has a series of 16
specimens with the following data: "Roanoke River, Roanoke, Vir-
ginia, 1888, U. S. Fish Commission, D. S. Jordan;" the catalogue entry
is dated 8 April 1889. As these seem to comprise at least part of the
syntypic material of N. albeolus, I hereby designate as lectotype of
Notropis megalops albeolus an adult, 76 mm SL, which retains the
original catalogue number (USNM 40177). Fourteen other specimens
of the original syntypic series now become paratypes and are recata-
logued as USNM 177840. The remaining individual is Notropis
ardens, and has been recatalogued under that name.
 DIAGNOSIS. A species of Luxilus distinguished from other mem-
bers of the subgenus by the following characters: Red pigment usually
lacking on body and fins of nuptial males, always absent in females;
dark pigmentation absent from dorsal and caudal fins; scale pockets
along side of body with little or no pigment, resulting in few or no
crescent-shaped bars; side of body silvery in life; no prominent, par-
allel, longitudinal stripes running along length of dorso-lateral region
of body (figure 15C); a light olive stripe, slightly wider than dorsal
stripe, extending along length of body on either side of mid-dorsal
stripe.
 N. albeolus is further distinguished from the closely related N.
cornutus by the following characters: scales relatively large, those in
the anterior dorso-lateral series (15) 17 to 20 (23); those in the circum-
ferential series (24) 26 to 30 (33); sum of anterior dorso-lateral and
circumferential scales (41) 43 to 50 (55); color of dorsal region olive-
green; side of body silvery in life, as contrasted to the more bronzy
aspect of N. cornutus; broad light stripes on either side of mid-dorsal
stripe less evident in breeding males; body usually slender and terete
in northern populations, body form in southern populations not ap-
preciably different from N. cornutus; maximum size apparently some-
what smaller, adult males attaining a maximum length of about 130
mm.
