ACANTHOPTERYGIANS. ;89 



because to the characters of a Perch, they add teeth somewhat resembling 

 those of the Pike. The edge of their preoperculum has but one simple 

 emargination ; their dorsal fins are separate ; some of the maxiUary and 

 palatine teeth are long and pointed. 



Lue. Sandra, Cviv.\ Perca lucio-perca, h. ; Sandre d' Europe ; 

 Bl. pi. li; Cuv. and Val. II, pi. xv. Is an excellent fish, of the 

 lakes and rivers of Germany, and of Eastern Europe. Longer 

 than the Perch ; greenish, with vertical brown bands ; from three to 

 four feet in length*. 



A second division comprises the Perches with seven branchial rays and 

 one dorsal. They are subdivided on grounds nearly analogous to those 

 which have led to the subdivision of the preceding ones; their teeth are 

 either hooked, or are all dense like the pile on velvet ; notches and spines 

 on the opercula, &c. 



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



Serranus, Cuv. 

 The Serrans have the preoperculum dentate ; the bony operculum ter- 

 minating 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. Several 

 beautiful species inhabit the Mediterranean, such as, 



Perca scriba, L. ; Cuv. and Val. II, xxviii, so named from having 

 some irregular blue lines on the head-i". 



Perca cahrilla, L. ; Cuv. and Val. II, xxix. Three oblique bands 

 on the cheek J. It is also found in the ocean. This species, and 

 perhaps the preceding one, were known to the Greeks by the name 

 of Chane, and were thought to consist exclusively of females. Ca- 

 volini assures us, that, in every specimen he examined, he found a 

 roe, at the lower end of which was a whitish part, which might be 

 considered as the milt. He believes them to be hermaphroditical. 

 The 



Anthias, bl, partini, 

 Are Serrani, in which both jaws and the end of the muzzle are armed 

 with very obvious scales §. The most remarkable species is,

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



f It is also the Perca marina, Brunnich; the Holocentrits maibms oi haxoche; the 

 IIol. argus of Spinola, and the Hoi. maroccanus of Bloch. The Hoi. fasciatus, Bl. 240, 

 appears to us nothing more than the same species somewhat changed.

 Lttbrus chanus of Gniel., or Holocentre chani, Lacep. ; the Bodian hiatule, Id. &c. Add

§ Most of our Merrffi are placed by Bloch among his Anthias, but we restrict this 

 genus to the species answering to our definition of the same. So little regard has
