42 THE FISHES OF OHIO. 
Genus: CYPRINUS. 
Cyprinus carpio Linnaeus. THE CARP. 
The Carp may be readily distinguished from any of our native Cyprinid@ by the 
presence of four long barbels, and by the very long dorsal fin—about 20 rays—preceded by 
a stout spine, which is serrated behind. Anal fin short, of about 5 rays, also preceded by 
aspine. The lower pharyngeal teeth, unlike those of any native American Minnow, are 
in 3 rows, I, I, 3-3,1, 1. The lateral line is complete. Many varieties have resulted from 
cultivation. Chief among these are the ‘‘ Full-scale,”’ in which the body is covered with 
strong scales, after the formula, 6-40-5; the ‘‘ Half-scale”’ or ‘‘ Mirror,” characterized by a 
few rows of very large scales; and the ‘‘ Leather Carp,” in which the scales are entirely” 
absent. 
The Carp was first introduced into the state to stock ponds and lakes, 
but, escaping from cultivation, has become generally distributed over the 
state and occurs in streams as well as ponds and lakes. Recorded for the 
state by Henshall, 1889, in Ross lake and Little Miami river; Lorain County, 
occasionally taken in the rivers, McCormick, 1892; Maumee river at Toledo 
(abundant), St. Marys river at Rockford, Tiffin river at West Unity, and 
west end of Lake Erie (abundant), Kirsch, 1893; Franklin County, ‘‘ of 
general distribution throughout the county,’’ Williamson and Osburn, 1897; 
Knox County, Big Jelloway creek, ‘‘ very common,’’ Parker, Williamson 
and Osburn, 1898; very common in Sandusky Bay, R. C. Osburn, 1899; 
Wheeling creek at Bridgeport, Ohio river at Bellaire, and Licking reservoir,. 
R. C. Osburn, Ig00. 
Genus: CARASSIUS. 
Carassius auratus (Linnaeus). GOLDFISH. 
The Goldfish may be distinguished from our native Minnows by the very long dorsal’ 
fin, preceded bya stout, serrated spine; the anal of 7 rays, witha similar spine. From 
the Carp it is distinguished by the absence of the barbels about the mouth, and by the 
teeth, which are 4-4. Asin the Carp, cultivation has produced many varieties. 
It has escaped from cultivation in some parts of Ohio, and has been 
reported by Henshall, 1888, as ‘‘not rare in the canal basin near Elmwood,. 
Hamilton County. 
Genus: TINCA. 
Tinca tinca (Linnaeus). TENCH. 
In the spring of 1898 a freshet carried away the banks of an artificial’ 
lake on the grounds of the Ohio State University, at Columbus, and many 
of the Tench, with which the lake was stocked, escaped into the Olentangy 
river, In September of the same year specimens were taken at the mouth 
of the small stream flowing from the lake to the river. Whether the Tench 
will hold its own in the streams of Ohio yet remains to be seen.
