This fish is an occasional visitor to our shores. In 1S15, several dozen of these followed 

 a ship into the harbor of New-York, and one of them was taken by a hook at the wharves, 

 in the month of August. It is this which is figured by Mitchill in lus Memoir on the Fishes 

 of New- York, but not accompanied with any description. On the plate it is marked Rudder- 

 fish or Perch Coryphene, and not C. hippuris, as has been erroneously stated. The description 

 was afterwards supplied by Mitchill himself, in a Supplement to his Memoir, published in 

 the American Monthly Magazine cited above. MM. Cuvier and Valenciennes were unac- 

 quainted with this description, and from the figure alone, supposed it to be their Trachinotus 

 argenteus. In this they are followed by the eminent American ichthyologist. Dr. Storer of 

 Boston, who was equally unacquainted with Mitchill's description. Finally, Mr. I. Cozzcns 

 of New-York, to whom I am indebted for an opportunity of describing this fish, not being 

 aware of Mitchill's description, described it in a paper read before the Lyceum some years 

 since, as a new species, under the name of Trachinotus cumhcrlandi. On a drawing of this 

 species found among the papers of Dr. Mitchill, which is now in the possession of Mr. Coz- 

 zens, it is labelled Coryphcna atra, or Black Rudder-fish. 



The specimen described above, was taken by hook near Shrewsbury inlet, in .Inly. It 

 appears now to be common enough to have received a popular name. Among the fishermen, 

 it is called the iS nip-nosed Mullet. In its stomach were found numerous shrimps, and it is 

 represented as being exceedingly active. It has been noticed by Dr. Slorer on the coast of 

 Massachusetts.
