 which is one and three fifths times the depth of the body; dorsal 

 and anal fins high in front, rapidly decreased backwards; caudal 

 fin low, and with a wavy outline; depth always more than half 

 length, and in the young the vertical diameter exceeding the 

 longitudinal; form varying with age, the body becoming more

 caught off Great Harbor, was kept alive at the station for about
