102 PISCES. 



They are small Fresh-water fishes of the East Indies, which 

 swarm in the pools and rivulets j several of them are transpa- 

 rent, (l) 



One of them is common in a pond in the island of Bourbon, 

 where they are prepared as anchovies, Jlmhassis Commersonii, 

 Cuv. and Val., II, xxv.(2) 



To this division belongs the 



Lucio-PercAj Cuv. 



Called by the French Brockets-Perches, or Perch-Pike, because, in 

 addition to the characters of a Perch, they are possessed of teeth 

 somewhat resembling those of the Pike. The edge of their preoper- 

 culum has but one simple emargination; their dorsals are separate^ 

 some of the maxillary and palatine teeth are long and pointed. 



Luc. Sandra, Cuv.j Perca lucio-perca, L.; Sandre d'Europe; Bl, 

 pi. li; Cuv. and Val. II, pi. xv. Longer than the Perchj green- 

 ish, with vertical brown bands; from three to four feet in length; 

 an excellent fish, found in the lakes and rivers of Germany, and 

 of Eastern Europe.(3) 



A second division comprises the Percoides with seven 

 branchial rays and one dorsal. They are subdivided in nearly 

 the same way as the preceding ones, as by their teeth which 

 are either hooked or all small and crowded ; notches and spines 

 on the opercula, &c. 



In the subdivision, furnished with hooked teeth, we find, 



Serranus, Cuv. 



Preoperculum dentate; the bony operculum terminating in one or 

 several points. This genus contains a vast number of species, and 

 may be subdivided as follows: 



Serranus, properly so called, 

 Or the Sea-Perch. No apparent scales on either of the jaws. Se- 

 veral beautiful species inhabit the Mediterranean, such as. 



(1) Several of them are comprised by M. Ham. Buchanan among his Chandae. 



(2) It is the Centropome ambasse, Lacep., IV, 273, and his Lutjan gymnocephale, 

 IV, 216 and III, pi. xxiii, f. 3. For the other species see Cuv. and Val., II, 181, 

 etseq. 



(3) Add the Berschik, or Sandre hatard {Perca volgensis, Gm.); the Lucio- 

 perca americana, Cuv. and Val., II, pi. xvi, p. 122.
