looking upwards. Eyes small and black, iris narrow 

 and yellow, the white patch appears as a second iris. 

 Chin and forehead between the eyes depressed, which 

 form a kind of rounded snout, mouth small, jaws 

 equal. I describe it from a drawing of Mr. Audubon. 



IX Genus. Hogfish. Etheostoma. Etheostome. 



Body nearly cylindrical and scaly. Mouth variable 

 with small teeth. Gill cover double or triple unser- 

 rate, with a spine on the opercule and without scales: 

 six branchial rays. Thoracic fins with six rays, one 

 of which is spiny; no appendage. One dorsal fin 

 more or less divided in two parts, the anterior one 

 with entirely spiny rays. Vent medial or rather 

 anterior. 



A singular new genus, of which I have already 

 detected five species, so different from each other 

 that they might form as many subgenera. Yet they 

 agree in the above characters, and differ from the 

 genus Scicna by the shape of the body and [II. 56] [jd] 

 mouth, and the divided dorsal fin. The name means 

 different mouths. I divide it into two subgenera. 

 They are all very small fishes, hardly noticed, and 

 only employed for bait; yet they are good to eat, 

 fried, and may often be taken with baskets at the 

 falls and mill races. They feed on worms and 

 spawn. 



ist Subgenus. Aplesion. 



Dorsal fin single, split in the middle. Meaning 

 nearly simple. 



2ist Species. Bass Hogfish. Etheostoma calliura. 

 Etheostome calliure. 



Body slightly fusiform and compressed, silvery,
