SIXTY-TWO SPECIES OF FISHES FROM LAKE ERIE 
327 
pectorals pointed; caudal long and deeply forked; ventrals inserted behind dorsal 
origin, not quite reaching vent. Characterized by elongate body; short compressed 
head with cheeks vertical and rather flat interorbital space; eye very large, high, 
entirely above premaxillary; mouth small, not reaching orbit, horizontal, lower jaw 
included; snout very abruptly decurved; preorbital bone conspicuous, rather oblong; 
no scales at this stage. 
Pigmentation. — Black chromatophores occur over upper jaw, top, and sides of 
heads, and two rows along either side of dorsal ridge from behind head to caudal. 
Three or four rows of very small spots mark the lateral line, but no dark lateral 
stripe is apparent as in some other cyprinids. There are a few subsurface chroma- 
tophores on dorsal surface of intestine near vent, and a double series from vent to 
caudal on ventral ridge. Heavy chromatophore marking shows at base of dorsal 
and anal, and the dorsal and caudal fins are marked. 
BREEDING 
From the present collections it is evident that Storer’s chub spawns during June 
and the first week of July, for all specimens taken throughout this period were in 
early stages of development. 
14. Rhinichthys atronasus lunatus (Cope). Black-nosed dace. [Bhinichthys 
lunatics Cope. Jordan, Evermann, Clark, p. 140.] 
RECORD OF CAPTURE 
Although this species strays only rarely into Lake Eiie, it may be found in great 
numbers in all small creeks of the region. 
DESCRIPTION 
The black-nosed dace is easily distinguished from the closely allied long-nosed 
dace ( R . cataract x) by the facts that in the former the snout scarcely projects beyond 
the slightly oblique mouth, and the broad lateral band extends on to caudal. 
17 .25-millimeter stage . — Total length, 17.25; standard length, 14.25; length to 
vent, 9.5; length of head, 4.0; snout, 0.75; diameter of eye, 1.3; greatest depth before 
vent, 3.1; greatest depth behind vent, 2.0; length to dorsal, 8.2; to anal, 9.6 milli- 
meters. Myomeres, 18 to vent plus 17 + behind. Dorsal II (rudimentary), 7 (with 
last divided at base in transparent specimen, appearing thus as an eighth ray), 
inserted behind middle of standard length; anal II (rudimentary), 6. Moderately 
elongate body; mouth small and slightly oblique; snout barely protruding.
