OF CERTAIN KINDS OF FISH. 21 



Prof. Ackley claims that the muscalonge actu- 

 ally copulates, and extrudes a limited number of 

 eggs after each copulation. Having never had an 

 opportunity of observing the habits of this fish, 

 while engaged in spawning, I am unable to give 

 an opinion respecting it.
