SIXTY-TWO SPECIES OF FISHES FROM LAKE ERIE 
367 
4.1; depth behind vent, 3.15; length to dorsal, 8.0; to anal, 14.1 millimeters. Myo- 
meres, about 22 to vent plus 19 behind (incomplete). Snout greatly produced and 
pointed, jaws equal; maxilla to hind margin of pupil; canines large; body elongate and 
terete. Dorsal XII-1, 18 ; anal II, 12 ; ventrals well developed, inserted before vertical 
from first dorsal spine; dorsals well separated; caudal deeply forked. 
Pigmentation. — Chromatophores are massed over tip of both jaws, top of head 
especially behind eye, and on operculum. A double series occurs on dorsal aspect 
of body, heaviest about bases of fins, and a double series around anal base followed by 
a single series behind to caudal. There are a few tiny chromatophores on the sides 
of the caudal peduncle and along the lateral line in this region. All fins are unmarked 
except for a few chromatophores outlining the caudal base. 
39 .0-millimeter stage . — Total length, 39.0; standard length, 33.0; length to vent, 
20.05 ; length of head, 10.5 ; snout, 4.5 ; diameter of eye, 2.9 ; greatest depth before vent, 
6.1; depth behind vent, 5.0; length to first dorsal, 12.0; to anal, 11.2 millimeters. 
Body rather slender, not much compressed, subterete; head pointed with maxilla 
reaching to hind margin of pupil only; dorsals well separated. Dorsal XIII-I, 17; 
anal II, 12. 
Pigmentation. — The 39-millimeter fish is white with numerous black chromato- 
phores covering all of body, most numerous on both jaws and over top of head. A 
slightly larger single series occurs at base of each marginal fin and along the lateral 
line posterior to the dorsals. The belly is white. The caudal is the only fin with 
many chromatophores. 
BREEDING 
The sauger spawns in early spring on shallow gravelly or sandy bars, often run- 
ning up rivers. With the beginning of warm weather it is reported to work its way 
downstream again and off into deep water. Whether the postlarval stages are 
common also in deep water, or whether this specimen was an exception, can not be 
determined from our scanty evidence.
