16th Species. Spotted River-bass. J-cjiomia notata. Lepo-

 This species differs merely from the foregoing, by having a 

 black spot on the margin of the opcrculc, 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 narrow 

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

 the same vulgar names and is tound 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 vcty strange that the gradual changes 

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

 many vulgar opinions arc often found to be correct.
