134 FISHES. 



round black spot on the flank; an excellent fish, that is sometimes 

 styled the Fish of St. Peter (a). 



Z. pungio, Cuv. ; Rond. 828, is another species, distinguished by 

 a stout bifurcated spine on the shoulder. From the Mediterranean. 



Capros, Lacep. 



Have the emarginated dorsal of the Dories, and a mouth still more pro- 

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

 with very rough scales. 



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

 lowish. It inhabits the Mediterranean*. The 



Lampius, Reizius. — Chrysotosus, Lacep. 



Have but a single dorsal, highly elevated before, as is the case with the 

 anal; and which has but one small spine at the base of its anterior edge. 

 There are ten very long rays to each ventral; the lobes of their caudal 

 are also very long, but all these prolongations become worn away with age ; 

 sides of the tail carinated. 



Lamp, guttatus, Retz. Violet spotted with white, and has red 



fins-}-. It attains a large size, and inhabits the Arctic seas; the only 



species known. 



Equula, Cuv. 



The Equula have only a single dorsal, but with several small spines, 

 the anterior of which are sometimes very long; the snout highly protrac- 

 tile; body compressed; edges of the back and belly dentated along the 

 fins. They are small fishes, several species of which inhabit the Indian 

 Ocean J. 



The snout of some of these species, when in a state of quiescence, is 

 singularly retracted ; by suddenly protruding it they are enabled to seize 

 upon such small fishes or insects as may pass within reach §. 



* It is also the Perca pusilla of Brunnich. 



f It is the Zeus regius, Bonn at. Encycl, Icthyol., f. 155; the Z. imperialis, Shaw, 

 Nat. Misc., No. 140; the Z. luna, Gmel.j the Z. guttatus, Brunnich, Soc. des Sc. de 

 Copenh. Ill, 3SS; the Scomber pelagicus, Gunner, Mem. de Drouth. IV, xii, 1; the 

 Chrysotose lune, Lacep. IV, ix, 3; the Moon-Fish, Duham., Sect. IV, pl.vi, f. 5; the 

 Qpah of Pennant, &c. 



% The type of this genus is the Scomber equula of Forskhal, of which Gmelin has 

 made his Centvogaster equula, and Lacep. his Casio poulain. Add, Eq. ensifera, Cuv., 

 or Scomber edentulus, Bl. 428, or Leyognathe argente, Lacep.; — Eq. caret, Cuv., Buss. 

 G6; — Eq.fasciata, Cuv., or Clupea jasciata, Lacep. V, p. 4(53, Mem. du Mus. I, xxiii, 

 2;— Eq. splendens, Cuv., Buss. 61;— Eq. daura, Cuv., Buss. 65; — Eq.totta, Buss. 62; 

 — Eq. ccma, Buss, et Seb. Ill, xxvii, 4, 63; — Eq. rucotiius, Buchan, XII, 35; — Eq. 

 minuta, Cuv., or Scomber mivutus, Bl. 429, 2, which may very possibly be the same 

 as the Zeus argentarius, Forster, IX, Schn. 96. 



§ tq. insidiatrix, Cuv., or Zeus iftsidiator, Bl. 192, f. 2 and 3. 



££\ (a) The legend on which this title is founded represents the Dory to have 

 been the iish from which St, Peter took the tribute money, and the impression of his 

 finger and thumb on the sides of its body were destined to commemorate the miracle.
