SIXTY-TWO SPECIES OP FISHES FROM LAKE ERIE 
365 
meres about 18 before vent plus 18 behind. Body greatly compressed, more elongate 
than adult yellow perch but decidedly deeper than pike perch of this length ; mouth 
large, with very small sharp teeth discernible but no canines, maxillary reaching to 
middle of eye; pelvic fins very close together. 
Pigmentation. — Bound and stellate chromatophores occur on head and a double 
line dorsally to end of body. Others are scattered also over sides of head and more or 
less evenly over sides of body. Many specimens have a dark subsurface area over 
stomach region. A rather indistinct ventral row of large stellate chromatophores 
extends to vent and an irregular double series from vent to caudal, darkest at base of 
anal. Dorsals, anal, and caudal are speckled. The banded coloration of the adult is 
not evident in these preserved specimens. 
Adult. — Specimens of 40 millimeters fully developed, definitely banded. 
BREEDING 
Our records of young from Lake Erie show that hatching may occur as early as 
the first week of May and continue until after the first week of July, but the height of 
the season in 1928 and 1929 at both ends of the lake was between June 7 and 17. 
39. Stizostedion canadense griseum (DeKay). Sauger; sand pike. [Cynoperca 
canadensis (Smith). Jordan, Evermann, Clark, p. 282.] 
RECORD OF CAPTURE 
Only one postlarval sauger was captured during the two seasons work of the 
Shearwater, a 14.5-rnillimeter specimen at 60 meters in the deep hole off Long Point 
Bay on July 30, 1928. Several young of about 28 to 30 millimeters were taken on 
June 29, 1929, in towings near the surface at the western end of the lake, and others of 
this size in seinings at the mouths of creeks. The adults are common in Lake Erie., 
seeking shallow water rather than the deeper parts. 
DESCRIPTION 
The earliest larva is distinguished from that of Perea jlavescens by the larger num- 
ber of myomeres, and the postlarva by its slenderer, less compressed body, larger 
mouth, and the characteristic fin-ray count of the adult, dorsal XII to XIII-I, 17 to 
18; anal II, 12. 
9.0-millimeter stage. — Total length, 9.0; standard length, 8.8; length to vent, 4.25; 
length of head, 1.8; diameter of eye, 0.47; greatest depth before vent, 1.45; depth 
behind vent, 0.65 millimeter. Myomeres, 16 to vent plus 26 behind (incomplete). 
Dorsal marginal fin fold originating shortly behind head, rising to highest point beyond
