 Ahramis americanus (L.) Giinther. 



A very good description, correct in every particular. This fish is 

 rarely or never called Shiner in the Ohio Basin, and it is very often con- 

 sidered by the fisherman as a Shad. If this genus be really distinct 

 from the European Ahramis^ as its serrated teeth indicate, the generic 

 name of Notemigonus must be adopted.

Hyodon tergisus Le Sueur. 



It is now generally conceded that there is but one species of Hyodon. 

 I find some variation in form of body and number of fin-rays in speci- 

 mens from dijQfereut waters, but nothing indicating specific distinction. 

 No author, so far as I know, has paid any attention to the numerous 



* Body fusiform, compressed, scaly. Vent posterior. Abdomen oblusehi carinaied, 

 not serrate; hack similar before the dorsal fin. Head scaleless, mouth small, nithoul tvdh, 

 lower jaw longer ; gill-cover double, opercule simple. Abdominal fins witli nine rays 

 and «o lateral appendage. Dorsal fin behind them above the vent. This genus differs from 

 Clupea by the carinated back and belly, without serratures, and the posterior dorsal. 

 The name means back half angular. 14th G. of my Prodr. N. G. Animals, 



tBack gilt olivaceous, remainder gilt silvery; fins yellow; lateral line following the 

 curve of the belly ; dorsal loith 9 rays, anal tvith 12 ; tail equally forked. 



Length from 4 to 8 inches, diameter one-fifth of the total length. Iris gilt. Tongue 

 short, toothless. Scales large, radiating with nerves. Head convex above and small. 

 Dorsal fin broad trapezoidal, the first ray longer. Anal broad also, but not so much. 

 Pectoral small with 16 ravs. Tail 24. Not uncommon in the Ohio, Kentucky, Miami, 

 &c. T.ift vulgar names are Gold Herring and Yellow Herring. It appears in the fall. 

 It does not bite at the hook. Flesh pretty good.
