HISTORY OF THE FISHES OF MASSACHUSETTS, iD 



Remarhs. This species, which, while preparing mj Report, I considered to be the 

 Trachinotus argeiiteus of Cuvierj is occasiooallv found in New Yorkj according to Dekaj^ 

 and is not unfrequeiitly met with at Holmes's Hole. Dr. Yale writes me, from the latter 

 place : " It follows vessels, or keeps near old casks or plaoks that are floatingj and 

 sometimes is found about the wharf-logs in our harbor." The only specimen I hare 

 known to be captured north of Cape Cod was taken at one of the wharves in this citj, 

 September 12, 1846. 



It is known by the fishermen at Martha's Vineyard as the Rudder-Jisfu
