ACANTHOPTERYGIANS . Wo 



SCOLOPSIDES, CllV. 



Have the second infra-orbital dentated and terminating near the edge 

 of the orbit in a point directed backwards, which crosses another point of 

 the third infra-orbital running in a contrary direction. The body is ob- 

 long, the mouth but slightly cleft, the teeth small and dense as the pile on 

 velvet, and the scales large. There are no pores in the jaws. From the 

 Indian Ocean*. 



Micropterus, Lacep. 



Have the body oblong; three pores on each side of the symphysis; the 

 last rays of the soft part of the dorsal separated from the others, and form- 

 ing a small particular fin; operculum without dentation "f~. 



Those Scienoides which have less than seven branchial rays and an in- 

 terrupted lateral line, form several genera of small, oval fishes, prettily 

 diversified in their colours, which may be distinguished as follows by the 

 armature of their head. They are manifestly related to the genus Cha?- 

 todon, and resemble, externally, several of our fishes with labyrinthian 

 branchiae. 



Amphiprion X, Bl. Schn. 



Have the preoperculum and the three opercular pieces dentated, the lat- 

 ter even furrowed; a single range of obtuse teeth §. 



Premnas, Cuv. 



Have one or two stout spines on the infra-orbital, and the preoperculum 

 dentated || . 



PoMACENTRUS^[, Lacep. 



Preoperculum dentated, operculum unarmed; a single range of tren- 

 chant teeth **. 



* Scol.kate, Cuv., named by Bloch Anthias japonicus, 325, f. 2; — Anth. Vosmeri, 

 Bl., 321, a poor figure, and the same as the Perca aurata, Mungo Park, Lin. Trans. 



III, 35; — Anth. bilineatus, Bl. 325, 1 ;— Scol. kuriata, Cuv. Russel. 106; — Scot. iy. 

 cogenis, Cuv., or Holoc. cilie, Lacep. IV, 371; — Scicgna ghanam, t Forsk., and several 

 new species. 



f But one species is known, the Microptere Dolomieu, Lacep., IV, iii, 3. We have 

 also some few more Subgenera of this subdivision, which we shall speak of in our 5th 

 vol. of Icthyology. 



% I greatly reduce the number of species of this genus, as composed by Bloch. 



§ Amph. ephippum, BL, 250, 2; — Amph. bifasciatus, BL, 316, 2; — Amph. polymnus, 

 BL, 316, \;—percula, Cuv., or Lutj. perchot, Lacep., IV, 239, Klein., Misc., IV, xi, 

 8; — Amph. leucurus, Cuv., Renard, VI, 49, and various new species. 



|| Clmtudon biaculeatus, BL, 219, 2, which is also the Helocentre Sonnerat, Lacep., 



IV, 391; and the Lutj. trifascialus, Bl„ Schn., 567; and Ksehlreuter, Nov. Com. 

 Petrop., X, viii, 6; Seb., Ill, xxvi, 29, is a variety of it; — Pr. Uiricolor, Cuv., Seb. 

 Ill, xxvi, 19, which is also the Scorpene aiguillonnee, Lacep. Ill, 268. 



^| We define them differently from Lacepede, and greatly diminish their number 

 by divisions. 



** Cluctodon pavo, BL, 19S, 1, which is the Pomacentre paon, Lacep., and his Holm: 

 diacanthe, IV, 338; — Pomacentrus cocruleus, Quoy et Gaym., Voy. Freycin., pi. 64, 

 f. 2;— P. punctatus, lb., \:—P. cmurginaius, Seb. Ill, xxvi, 26, 27, 28; — the Hoi 

 negrillon, Lacep. IV, 367.
