common in the Ohio, Kentucky, Miami, &:c. The vulgaj* 

 names are Gold Herring and Yellow Herring;. It appears in 

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

This genus has been minutely described by Mr. Lesueur; yet 

 it is strange that he should have hardly noticed the abdominal 

 appendages, similar to those of the genera Clufiea^ Salmo, Spa- 

 7'USj Sec. which are very large, acute flat scaly adipose, and on 

 the external and lateral side of the base of each abdominal fin. 

 This genus differs from Clu/iea and the foregoing genera by its 

 mouth and teetn, abdomen and abdominal fins; it approximates 

 also to Erijthrinus and Chirocentrus. There are alreadyfive spe- 

 cies known, all railed Herrings on the Ohio: they appear early 

 in the spring and disappear in ths fall. They live on small 

 fishes, insects, worms, and spawn: they often bite at the hook; 

 and are taken in great quantities with the seines. I have adopt- 

 ed Mr. Lesueur's name, although it is not without objection, 

 particularly by its similarity with Diodon in sound; but having 

 divided the genus into three subgenera, one of the names given 

 to them might, if needful, be adopted as the proper generic 

 name. 



1st Subgenus. Amphiodcn. 

 Body lanceolate, lower jaw longer, dorsal fin beginning oppo- 

 site to the base of the anal fin. The name means toothed all 

 over.
