3. Fimephales notatus (Rafinesque). Blunt-nosed minnow; “Sucker.” 
One of tlie most important and abundant baits. It is easily distinguished by its 
sucker-like head and the black spot at the base of tail. Frequently seen around 
wharves feeding on decayed fish. Takes the hook readily; at Cape Vincent dozens 
were caught ou a piuhook baited with a piece of angleworm. The six specimens pre- 
served were about 3 inches long. 
4. Notropis hudsonius (De Witt Clinton). Spawn-eater; “Cliub.” 
Reaches a length of 10 inches, and is abundant in Lake Ontario. It is a common 
bait for bass and pike. Three specimens were preserved, the largest 3-1 inches long. 
5. Notropis wliipplei (Girard). Silver-fin; “Shiner.” 
The name u shiner ” was heard applied to this minnow by fishermen. It is less 
common than the preceding species. A single specimen was preserved. This was a 
male, 31 inches long, with the head, nape, and back anterior to dorsal fin thickly beset 
with short, broad-based spines. 
6. Notropis megalops (Rafinesque). Common shiner ; Bed-fin; Dace. 
The most abundant member of the genus Notropis and one of the minnows most 
commonly used for bait. Eighteen specimens were collected, the largest of which 
was 41 inches long. The species attains a length of about 8 inches. A number of 
the examples obtained were affected with the larvse of a parasitic worm (Trematod), 
manifested in the form of small round black spots thickly scattered over the body 
and fins. These parasites were found also on Catostomus teres and Semotilus atromac- 
ulatus. In Irondequoit Bay minnows kept in captivity were very frequently attacked 
in this way. 
7. Notropis heterodon (Cope). 
A single specimen, 2£ inches long, has been identified by Dr. Charles H. Gilbert 
as belonging to this species. 
8. Hybopsis kentuckiensis (Rafinesque). Silver-fin; Horny -head; “Chub.” 
A very common and important bait minnow for bass and pike. It reaches a 
length of 10 inches, but none of the seven specimens preserved was over 3J inches long. 
9. Semotilus atromaculatus (Mitchill). Horned dace. 
A common bait fish, usually found in the clear streams entering the lake. The 
five specimens obtained were only about 2 inches long, although the fish attains a 
length of 10 or 12 inches. The fall fish or roach ( Semotilus bullaris ) was not seen, but 
it is an abundant inhabitant of the lake region, where it reaches a much larger size 
than the preceding. 
10. Clupea pseudoharengus (Wilson). Alewife ; “Shad.” 
This brilliant silvery fish is often used for bait when immature. One example, 2£ 
inches long, was received from a bait fisherman at Grenadier Island August 12,1891.
