Fig. 183. Hog-choker. Achirus fasciatiis. 



The hog-choker is found from Massachusetts to Texas, and is the best known 

 of the American soles. It has the interesting habit of ascending streams, and in 

 p!aces is found permanently in fresh water. As it rarely exceeds 6 inches in 

 length, it is of practically no food value. 



At Beaufort it is apparently rare, but in the lower courses of the North Car- 

 olina rivers it is common, it is a regular but uncommon inhabitant of Neuse 

 River as high up as Raleigh, is abundant in the western end of Albemarle Sound,
