This beautiful little fish, which furnishes a delicate article of food, is usually rare in our 

 waters, but visits us in almost incredible numbers at irregular and generally distant intervals. 

 One of these visits happened to coincide with the arrival of the great and the good La Fayette 

 at New-York, in the sununer of 1824. His name was unanimously given to a fish, which 

 was considered as entirely new, and this name it still retains. It must be very common on 

 the southern coast, but I cannot find that it has in those parts received any popular name. If 

 I am correct in supposing that the S. multifasciata of Lesueur, described from a dried spe- 

 cimen, is identical with the Lafayette, it is common on the coast of Florida. Thus far, there 

 is reason to believe that the coast of New-York forms its extreme northern geographic limits. 

 I see no good reason for changing the prior and characteristic name given to it by Dr. 

 Mitchill.
