species of Rafinesque. The name Glossodon was i)ublislied by Eafi- 

 uesqae for this genus in September, 1818, witbiu a few days of the publi- 

 cation of Hiodon by Le Sueur. It is not known which has priority, 

 but as Le Sueur's paper was first icritten, and as his name has come 

 into common use, it is probably best to retain it.

* XV. Genus, MINNY, MINNILUS, Minny. (p. 4.').) 



* Body elougated, somewhat compressed, covered with small scales. Veut medial 

 Head flat above, ami somewhat shielded. Gill-cover double, scaleless, three branchial 

 rays. Mouth diagonal, small, toothless and beardless, without lips, lower jaw shorter 

 and narrower. A small trapezoidal dorsal fin, nearer to the head than to the tail, op- 

 posite to the abdominal fins, and without spines. Abdominal fins with eight rays, and 

 without appendages. (Tail forked in all the Ohio species.) 



There are in the United States more than fifty species of small fresh-water fishes 

 (and in the Ohio waters more than sixteen species), commonly called Minnies, Min- 

 nows, Bait-fish, Chubs, and Shiners, which should belong to the genus Cyprinus of Lin- 

 ntens, or, rather, to the part of it which has been called Leuciscus by Klein and Cuvier; 

 ■which subgenus (or genus) is distinguished by a small dorsal fin, no spines nor beards ; 

 but as the genus Cyprinus forms now a large family, and even the genus Leuciscus must 

 be divided, since it contains more than one hundred anomalous species, differing in the 

 position of the dorsal fin and the vent, the number of rays to the abdominal fins, Slc, 

 I venture to propose this and the three following genera. Three other difierent genera 

 might be established upon the European species, distinguished as follows: 



Bohula. Dorsal fin nearer to the tail, abdominal fins with nine rays and an appen- 

 dage; upper jaw longer. 



Phoxinus differs by ten abdominal rays and no appendage. 



Alburnus differs from Dohula by no appendage and the lower jaw longer. 



Besides my genus Hemiplus (Aunals of Nature), which has the vent posterior, the 

 lower jaw longer, only five rays and an appendage to the abdominal fins. 



All these small fish are permanent; they feed on worms, insects, univalve shells, 

 and spawn ; they bite at a small hook, baited with worms or flies, and they form an 

 excellent bait for all the larger fish which feed upon them. They are good to eat when 

 fried.
