. Bumper. Chlaroscombrus chrysurus. 



While the bumper is found from Cape Cod to Brazil, it is not common north 

 of Charleston and has rarely been taken in North Carolina waters. One small 

 specimen was collected at Beaufort by Dr. Jenkins in the summer of 1885, and 

 another 1.87 inches long, now in the Beaufort laboratory, was obtained in the 

 harbor Sept. 4, 1901, from the bell-cavity of a medusa (Dactylometra.) Three 

 other specimens., the largest 4.25 inches long, were taken inthelaboratorypound 

 net in Beaufort Harbor, in July and August, 1905. The species reaches a length 

 of a foot and is very handsome, but has no food value, the flesh being dry and 

 bony. The North Carolina fishermen do not appear to know the species.
