SIXTY-TWO SPECIES OF FISHES FROM LAKE ERIE 
359 
Pigmentation. — A few chromatophores occur around jaws and over top of head, 
a few on cheeks and below angle of jaws, very few on underside between gills, many 
over top of air bladder, very few on either side of dorsal fin, a double series around anal 
fin, and a single series of about 20 small, uneven spots from anal to end of body. A 
few chromatophores appear also at base of caudal and on the fin itself. 
Young adult, 89 .5-millimeter stage . — Dorsal II, 9 (first 2 spines very weak, repre- 
sent unsegmented rays); adipose fin present; anal I, 7; ventrals 1, 8 (spine rudi- 
mentary). Total length, 35.5; standard length, 28.0; length to vent, 17.0; length of 
head, 9.0; greatest depth, 6.9; length to origin of dorsal, 13.5; diameter of eye, 2.5 
millimeters. Myomeres', 15 to vent plus 19 behind. Body moderately elongate, some- 
what compressed; caudal peduncle long and slender; head conical, pointed; mouth 
small, horizontal; maxillary short, narrow, no supplemental bone, not reaching eye; 
very small teeth in bands on premaxillaries and mandible. Dorsal short, median, and 
anal origin about opposite end of dorsal. Fully scaled. (Scales not shown in fig. 79.) 
Pigmentation. — Many chromatophores occur over whole body, arranged laterally 
in about six indefinite bands. All fins except adipose are marked. 
BREEDING 
Adults live usually in rather deep water but spawning occurs inshore between 
early May and the first half of July; its height probably occurs around the middle of 
June. 
Family SERRANID^l, Sea basses 
37. Lepibema chrysops (Rafinesque). White bass, silver bass. 
RECORD OF CAPTURE 
Young white bass showing adult characters are fairly common in Lake Erie near 
the mouths of creeks, and larvae from 3.7 to 13.5 millimeters were taken quite abun- 
dantly at the western end of the lake on June 29, 1929. Adults are common in the 
Niagara River, the lake, and at the mouths of its tributaries. 
DESCRIPTION 
The very large mouth, deep compressed body, and few myomeres distinguish 
the white bass from other Lake Erie larvae.
