The Scams carvleus of Blocli & Schneider is, however, free from any 

 confusion with chry softer urn or related species. Scams trilohatus Lac6- 

 pede is somewhat doubtful, and Sparus holocyaneos Lac. is involved in 

 confusion with Sparisoma chrysoptemm. The obtusns and michalls of 

 Poey are probably forms of cceruleus. Scams quadrispinosiis 0. & V. is 

 evidently different, having two canines on each side of the upper jaw.
