Pagrus bertheloti and auriga are the same fish according to the 

 observations of the Rev. I^ T. Lowe, the former representing old 

 specimens of the latter. In specimen c, which is twelve inches long, 

 the third dorsal spine also is more than one-half the height of the 

 body, whilst in the fishes on which Pagrus bertheloti was founded, 

 the length of the same spine is 2| in the height of the body.
