ca, the former generally distributed in the drainage of the Mississippi basin, the 

 latter contined, so far as known, to the southern Alleghany region. Protonopgis hoi-- 

 rida is the well-known hell-bender of the Ohio. It is aquatic in its habits, and is fre- 

 quently caught by fishermen on their set-hooks. The following accounts of its habits 

 are given by Messre. Townsend and Frear in the American Naturalist for February 

 and April, 1882. 



" The Protonopsis, called ' alligator ' and ' water-dog,' is an exceedingly vora- 

 cious animal, feeding on fish, worms, crayfish, etc. ; some of those taken by me 

 dis^oro-ed cra}'fish shortly after being caught. May it not be a scavenger of the

 region, from its troublesome habit of taking bait placed in the water for nobler game.

When thus hooked, its vicious biting and squirming, together with the slime which 

 its skin secretes, render it exceedingly disagreeable to handle. It is often hooked in

 the amphibian's flat head is often rendered still flatter by a lively application of the 

 sjjortsman's boot-heel. 



"In the early summer, when the water is clear, Protonopses arc often to be 

 seen on the bottom in considerable numbers. Once, when fi.shing with some friends 

 from off a large rock in the Loyalhanna creek, we saw quite a shoal of them moving 

 sluggishly about among the stones on the bottom. They would quickly take our 

 hooks baited with a piece of meat or a fish head. In one instance two large ones laid 

 hold of the same bait and were promptly landed on the rock. In a few minutes we 

 had a dozen. Last August I fished the same spot for them, but without success. 

 Acting on the advice of a ' native ' (which was to droj) some bait — dead fish, etc.,
