SCLENOIDEjE.

seven brancliiostegous rays. Scolopsides, Amphiprion, Premnas, Dascyllus, and 

 Etroplus, which are peculiar to the Red Sea, Indian Ocean, and Polynesia, have 

 one continuous dorsal, and fewer than seven gill-rays. Diagramma and Poma- 

 centrus, which have also seventeen or eighteen species each in these seas, have 

 also a single dorsal, but the former has seven gill-rays- Maquaria, containing a 

 solitary species which inhabits the Macquarie, a river of New Holland, belongs to 

 the same subdivision with the genera peculiar to the Polynesian seas. We have 

 enumerated eighteen genera, twelve only remain, and of these Scicena, Otolithus, 

 Corvina, Umbrina, and Pristipoma, typical forms of the Scisenoidese that have 

 seven gill-rays, and all but the last, having a double dorsal, are the most widely 

 diffused, as the subjoined table shows. Glyphisodon and Heliases, Avhich have the 

 widest distribution among the genera with fewer than seven gill-rays, have smooth 

 preopercula, and are aberrant forms leading to the Sparoideas, or in some points of 

 view to the Labroideee.
