ORDER I. BONY FISHES. ACANTHOPTERYGII (SPINY-FINS). 155 
TremMNopON (Blue-fish). Tail unarmed, spines or small fins before the anal, 
first dorsal small, second and anal small, scales, one row of trenchant teeth in 
each jaw, with small, crowded ones behind, and on the vomer, the parietals, 
and tongue; seven rays on the gills, and the gill-lid forked. There are spe- 
cies common to both oceans, and about the size of the common mackerel. 
Caranx, have the lateral line, with scaly plates, keeled, and often spinous, 
horizontal spine before the first of the two dorsals, last rays of the second 
dorsal often detached, some spines or a small fin before the anal. These 
fishes do not appear to have any geographical limits, but are found in all 
seas. They resemble mackerel, and are called Bastard or Horse-mackerel, 
and they sometimes make their appearance in immense shoals, literally 
“banking the sea.” They feed on the fry of herrings, and are not in much 
estimation as food. 
“Vomer. — This genus have the body more and more compressed and cle- 
vated in the different sub-genera, while the armature on the lateral line 
diminishes, and the skin becomes smooth, like satin, without any apparent 
scales. They have no teeth, except short and fine ones crowded together ; 
and the sub-genera are chiefly distinguished from each other by various fila- 
mentary prolongations of some of the fins. The following are the sub- 
genera : — 
© Olistus. — These resemble Scttu/w, a sub-genus of Caranx, but the mid- 
dle rays of the second dorsal are not branched, but merely articulated, and 
extend in long filaments. 
“ Scyris. — Nearly the same in form and filaments, but the spines of the 
first dorsal hidden in the edge of the second, and the ventrals short. 
* Blepharis, has long filaments to the second dorsal and anal, the ventrals 
very long, and the spine scarcely above the skin; their body is very ele- 
vated, but their profile not so vertical as that of some of the other sub- 
genera found in the warm seas; and, in the West Indies, one species is 
called the “ Cobbler.” Gallus, similar to the last in all respects except hay- 
ing the profile more vertical. Argyrezosws, has the profile still more ver- 
tical, the first dorsal definitely formed, and some of its rays extended in 
filaments, as well as those of the second dorsal; the ventrals are also very 
long.” 
Zeus, the Dory, has the first dorsal deeply notched between the spines, 
and the intermediate membranes extend into long filaments, together with 
the forked spines along the basis of the dorsals and the anal. One species, 
the Common Dory (John Dory), is yellowish-brown, with golden or silvery 
reflections, according to the position of the light, with a round black spot 
margined with white on the shoulders. “The Dory has been a renowned fish 
since the days of the ancients, who styled it not the fish of Jove, but Zeus,
