II (very weak), 7; ventrals just posterior to front of dorsal. Body scaled at this 
stage, with abdomen rounded and scaled (scales on lower half of body not shown in 
fig. 26); scales large, 6-40 to 45-5. Body rather short and stout; mouth large and 
low; upper jaw almost terminal; conical snout of later stages barely perceptible; pre- 
orbital wider than eye; small barbel apparent at tip of maxillary. 
Pigmentation. — The young crested chub is white with dorsal aspect of head 
covered by round black chromatophores. Small, even spots occur on dorsal aspect 
of body to vent with a double row of larger ones along dorsal ridge. Dorso-lateral 
aspect has small chromatophores arranged along margins of scales. A heavy lateral 
stripe extends from tip of snout to base of caudal, forming a darker caudal spot. 
There are a few chromatophores in ventro-lateral region of tail and around anal, 
but otherwise the ventral aspect is unpigmented. All fins except ventrals are marked, 
the pectorals most sparingly. The brilliant colors of the adult are not yet evident. 
BREEDING 
The name of crested chub arises from the character of the head of the breeding 
male, for it is swollen into a crest and covered by tubercles. Often a red spot appears 
on either side of the head. John Greeley (1929) observed a breeding male guarding 
its nest on July 9, 1928, in Silver Creek, at a temperature of 83° F. The nest was 
built of pebbles which had been painstakingly picked up and put into place sepa- 
rately. The male chub spawned with each of several females, and after each spawning 
act piled more stones upon the nest to cover the eggs. After preservation in formalin 
these eggs measured 2 millimeters in diameter. 
13. Erinemus storerianus (Kirtland). Storer’s chub. 
RECORD OF CAPTURE 
Larval stages up to 7.5 millimeters were taken from Buffalo to Rondeau during 
the latter half of June and the first week of July, usually in bottom hauls in water 
of from 18 to 20 meters depth. At the western end of the lake in 1929 early larval 
stages were taken commonly from June 7 until July 2, being most abundant on the 
latter date. Storer’s chub is a common species in the Lake Erie region alongshore, 
at creek mouths, and ranging out into comparatively deep water.
