ACANTHOPTERYGII. 155 



Argyreiosus, Cuv. 



The profile still more elevated^ the first dorsal decidedly mark- 

 ed, and some of its rays prolonged into filaments like those of the 

 second. Their ventrals also are much lengthened.(l) In 



Vomer, properly so called^ 



The body is compressed, and the profile vertical, as in Gallus 

 and Argyreiosus, but there is no prolongation to any of the fins.(2) 

 The genus 



Zeus, Lin. 



After abstracting the Galli and Argyreiosi, Sec, comprehends 

 fishes with a compressed body, an extremely protractile mouth like 

 that of the Menides, and having but few and weak teeth. They re- 

 quire however to be greatly subdivided. 



Zeus, Cuv. 



Dorsal emarginate, its spines accompanied by long slips of the 

 membrane; a series of bifurcated spines along the base of the dorsal 

 and the anal. 



Z.faber, L., Bl. 41. (The Common Dory.) Yellowish, with 

 a round black spot on the flank; an excellent fish, that is some- 

 times styled the Fish of St Peter. 



Z.pungio, Cuv.; Rond. 328, is another species, distinguished 

 by a stout bifurcated spine on the shoulder. From the Medi- 

 terranean. 



Capros, Lacep. 



The emarginaled dorsal of the Dories, and a mouth still more pro- 

 tractile; but no spines along the dorsal and anal; the entire body co- 

 vered with very rough scales. 



But one species is known, Zeus aper, L., which is small and 

 yellowish. It inhabits the Mediterranean. (3) The 



(1) Zeus vomer, Mus., Ad. Fred, xxxi, 9, and better, Bl. 93, 2, or Macatuia, 

 Marcgr. 161; Zeus rostratus, Mitch., op. cit. II, 1. N.B. The Zeus niger, Bl., 

 Schn., is founded on a mistake; a figure of the Macatuia, in the work of Marcgrave, 

 p. 145, having been placed next to the description of the Guaperva, or Chxtodon 

 arcuaius. The Selene argtntie, Lacep. IV, ix, 2, is an Macatuia, whose first dorsal 

 and ventrals had been worn. His Selene quadrangulaire, is the Chaet. faher.

(3) It is also the Perca pusilla of Brunnich.
