Generic Characters. — Form of the body, the branchial apertures and fins, 

 like those of the Lampreys ; upper lip semicircular, with a straight, transverse 

 under lip ; mouth without teeth, but furnished with numerous short membra- 

 nous cirri. 



This small fish is very similar in its general appearance to 

 the young of the Lampreys found in fresh water ; but its 

 prominent lip is in the form of a horse-shoe, and the circle 

 not being complete, it has not the power of adhering to 

 stones and other substances like the true Lampreys, but 

 generally hides itself in the mud or loose sandy bottoms of 

 rivers and brooks in this country, in most of which it will be 

 found, but requires close search to detect it. It is of little 

 value, seldom exceeding six or seven inches in length, and is 

 about as thick as a large quill.
