SIXTY-TWO SPECIES OF FISHES FROM LAKE ERIE 
335 
Pigmentation.' — The 19-millimeter N. hudsonius is characterized especially by a 
definite black spot at base of caudal. The head is sparsely pigmented, and 3 rows of 
chromatophores are apparent on dorsal aspect to caudal. Small cliromatophores are 
widely and irregularly placed in dorso-lateral region, and a few surface and subsurface 
chromatophores over operculum. A few occur below lateral line and subsurface 
chromatophores throughout its length, ending with a black spot at caudal. A double 
row extends backward from vent on ventral ridge. Dorsal and caudal are pigmented. 
j l JL. 2 5 -millimeter stage . — Total length, 14.25 ; standard length, 11.5; length to vent, 
8.0; length of head, 3.0; snout, 0.6; diameter of eye, 1.0; greatest depth before vent, 
2.1; depth behind vent, 1.5; length to dorsal, 6.0 ; to anal ,8.1 millimeters. Myomeres, 
21 (22) to vent plus 16 behind. Dorsal I (rudimentary), 8; anal I (rudimentary), 
9; ventrals immediately under front of dorsal; caudal rather long and forked. Body 
moderately elongate; head conical with short, blunt snout; mouth rather small, nearly 
horizontal; lower jaw very slightly shorter. 
Pigmentation. — The head is more sparsely pigmented than in most other species 
of the genus. Chromatophores occur in about 3 rows along dorsal aspect, a few on 
operculum, and very many below surface on 2-chambered air bladder. A series 
marks the lateral line, surface and subsurface, and a prominent black spot is apparent 
at base of caudal. A few chromatophores occur beneath lower jaw, and a double 
series on ventral line backward from vent. The dorsal and caudal are pigmented. 
BREEDING 
The spot-tailed minnow spawns alongshore in late June and early July. 
21. Notropis atherinoid.es Rafinesque. Lake shiner; emerald minn ow. 
RECORD OF CAPTURE 
Only 6 small larvae were taken in 1928, from July 30 to August 1, in the vicinity 
of Long Point Bay. During 1929, however, it was one of the most abundant species 
taken by the survey, as nearly every net towed from July 2 to August 20 contained 
from 1 to 500 of these larvae. In the western part of the lake they were even more 
common between June 19 and August 17, as many as 3,000 being captured in a 
single tow. Adults are very common in the lake in deep as well as in shallow water. 
DESCRIPTION 
The newly hatched larva is characterized by its very slender unpigmented body 
with even the eyes colorless, clear elongate yolk, and myomere count of 23 to vent
