 pome sauinone.

 ish spots, beneath white: preopercule simple, head without su- 

 tures, lower jaw hardly longer, spines flat, short, acute, and de- 

 current above and beneath, opercule acute beneath the spinest

Length from 6 to 24 inches. Vulgar names White Trout, 

 Brown Trout, Trout Pearch, Trout Bass, Brown Bass, Black 

 Bass, Black Pearch, Sec. Common in the Kentucky, Ohio, 

 Green; and Licking rivers. Sec. It offers a delicate white flesh, 

 similar to the Pei-ca Salmonea. It is a voracious fish, with 

 many rows of sharp teeth on the jaws and in the throat. It 

 bites easily at the hook, and eats suckers, minnows, and chubs.

 sal with 25 rays, whereof 10 are spiny, slightly depressed be- 

 tweeri them: anal rounderl sm^ll, S and 1 I r^iys. Pectoral acute 

 trapesoidal 18 rays. Thoracic 1 and 5, spiny ray half the length- 

 Tail with 24 rays. Iris silvery. 



16th Species. Spotted Riv^er-bass. Lepornis notata. Lepo- 

 :^ie tache. 



This species differs merely from the foregoing, by having a 

 "black spot on the margin of the opercule, two diagonal brown 

 stripes on each side of the head below the eyes, and all the fins 

 yellow, except the tail which is black at the end, with a narrovv 

 white tip. It is also smaller, from 3 to 8 inches long. It bears 

 the same vulgar names and is found along with it, of which some 

 fishermen deem that it is the young. But I have seen so many 

 false assertions of the kind elsewhere, that I am inclined to doubt 

 this fact, as it would be vet y strange that the gradual changes 

 should be so great. Yet this ought to be enquired into, since 

 many vulgar opinions are often found to be correct. 



17th Species. Suntish Riyer-bass. Lepoviu icihcloides, 

 Leporne ictheloide.
