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 Clupea, Salmo, Spams, &c. which are 

 very large, acute flat scaly adipose, and on the exter- 

 nal and lateral side of the base of each abdominal 

 fin. This genus differs from Clupea and the fore- 

 going genera by its mouth and teeth, abdomen and 

 abdominal fins; it approximates also to Erythrinus 

 and Chirocentrus. There are already five species 

 known, all called Herrings on the Ohio : they appear 

 early in the spring and disappear in the fall. They 

 live on small fishes, insects, worms, and spawn : they 

 often bite at the hook ; and are taken in great quan- 

 tities with the seines. I have adopted Mr. Lesueur's 

 name, although it is not without objection, particu- 

 larly 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. 



1 st Subgenus. Amphiodon. 



Body lanceolate, lower jaw longer, dorsal fin be- 

 ginning opposite to the base of the anal fin. The 

 name means toothed all over.
