30 FISHES OF THE CONNECTICUT LAKES. 
by the same conditions as are sought by Chrosomus, at least they fre- 
quently occur together. The only locality in this region in which 
it was found was in the meadow-spring holes along Indian 
Stream. That it occurs in other places is likely. It is an attractive 
bait, and doubtless furnishes food for other species. Its spawning 
time is in early summer, but its habits have not been observed. It is 
believed that this is the first time that it has been collected east of 
Michigan except in a few places in northern Maine and in New Bruns- 
wick. It is a handsome minnow, attaining a larger size, about 4 
inches, but closely resembling Chrosomus in color, and will readily 
take a hook baited with worm. 
7. Reprrn. Notropis cornutus (Mitchill). 
Head 4.12 in length without caudal; depth 4.34; eye 4.80 in head; snout 3; 
dorsal 8; anal 9; scales S-44-3. 
Head of moderate length, rather deep and compressed, upper profile strongly 
curved to snout, rounded between eyes; muzzle bluntly rounded; mouth mod- 
erate, oblique; lower jaw somewhat included; maxillary not reaching front of 
eye; eye rather large, high, its lower margin about on level with upper lip; body 
deep and compressed; scales large, much deeper than long on side of body for- 
ward; 24 on back in front of dorsal; lateral line decurved; dorsal high in front; 
tips of first rays of dorsal when depressed extending slightly beyond the tips of 
the last; tips of first anal rays not reaching tips of last rays when depressed ; 
pectorals and ventrals pointed; pectoral not quite reaching ventral; ventral 
reaching vent, nearly to front of anal; caudal forked; peritoneum black. The 
above description from a male individual 4.68 inches long from Second Lake. 
Five specimens from Round Pond ranged in length from about 4 inches to 5 
inches, averaging 4.77 inches; head in length without caudal ranged from 3.95 
to 4.34, averaging 4.06; depth 3.95 to 4.84, averaging 4.14; eye in head 3.83 to 
4.18, averaging 4.03; snout 3.12 to 3.58, averaging 3.29; scales 40 to 42, aver- 
aging 41; dorsal rays 8; anal 9; longest dorsal ray 1.21 to 1.86 in head, aver- 
aging 1.29. 
Upper part of head, back, and sides shiny metallic blue and olive; margins 
of scales, nearly to belly and quite to anal, dusky, and otherwise somewhat 
sprinkled with black dots; belly white; an indefinite dark metallic blue stripe 
along side, most distinct posterior to dorsal; a black stripe from nape along 
median line of back, passing each side of base of dorsal, reuniting, and con- 
tinuing to caudal; fins of male margined with red in breeding season, when all 
tints are more brilliant. Distinguished from other minnows in the region 
chiefly by the laterally compressed form and the fact that the scales on the 
front part of side are deeper than long. 
Besides “ redfin,” English appellations such as “ shiner,” “ min- 
now,” “ dace,” ete., singly or in conjunction with the attribute “ redfin ” 
are common. This is, however, preeminently the “ redfin ” of anglers, 
although other cyprinids as well as other fishes have red fins at times, 
and this species does not always have them. The red fins of this 
fish are nuptial decorations of the male. 
The distribution of the redfin is very extensive. According to 
Jordan and Evermann it inhabits the entire region east of the Rocky
