Pigmentation. — There are three distinct shades of brown in the living specimen, 
which may be described as a dark seal-brown, reddish-brown, and bronze. The 
bronze has some metallic sheen and the lightest intensity of all. The dorsal surface 
is covered with closely distributed, tiny, round, reddish-brown chromatophores, 
those on the prolonged jaws being larger, stellate, and fewer toward the center line. 
Viewed from the side, some exceptionally large seal-brown chromatophores appear on 
jaws extending to eye, a narrow line encircling orbit, and thence a broad band of 
bronze to the posterior margin of head. On either side of this postorbital band is a 
white band, met above by the reddish-brown dorsal region and below by the dark 
ventral chromatophores. Behind the head, dorsal chromatophores extend down the 
sides for one-third of their depth, continuing to extreme tip of body on either side 
of notochord. Below this is an irregular white band with a very broken bronze band 
interposed upon it, followed below by a wide median band of deep seal-brown and 
bronze extending the full length of body, continued to top of lower part of caudal 
fin. Below the median band, a white band is apparent, which becomes narrower 
and is lost behind the anal fin, bounded below by the seal-brown ventral region. The 
underside is characterized by the same white color as the sides (as a pigment, not the 
opaque, colorless white of young forms). An arrow-shaped patch of white marks the 
lower surface of head, and behind this the ventral aspect is mostly seal-brown with 
only small irregular markings of white. Base of pectorals is white with a median- 
brown band about one-third the width of the base, not extending to tip of fin. Some 
reddish-brown is evident on dorsal, and the brown ventral chromatophores extend out 
less than half the distance to tip of anal fin. 
BREEDING 
The long-nosed gar spawns in late spring and early summer in warm shoal 
water, often running up smaller streams in company with the sturgeons. The eggs 
are probably attached to weeds, and the young remain among the weed beds close 
inshore during their first summer. 
Family HIODONTID/E, Mooneyes 
2. Hiodon tergisus Le Sueur. Mooneye; toothed herring. 
RECORD OF CAPTURE 
None of this species were taken by townets in the deeper waters of eastern Lake 
Erie during the survey, but schools of young were found at many places close inshore 
and at creek mouths. Among the 1929 collections from the western end of Lake 
Erie were eight larvae, 12.0 to 15.5 millimeters in length, taken on June 7 at the 
surface in water of 15 to 19 feet. A 6.5-millimeter larva which seems to be identical 
with the above was taken on June 10, off the mouth of the Maumee River. 
DESCRIPTION 
The elongate herringlike body with blunt projecting snout and large mouth at 
all stages is unlik e any other species taken by the survey. 
6 .5 -millimeter stage . — Total length, 6.5; standard length, 6.3; length to vent, 
4.3; length of head, 1.16; diameter of eye, 0.3; greatest depth before vent, 0.85; depth 
behind vent, 0.4 millimeter. Myomeres incomplete at beginning and end of body but
