American food and game fishes : a popular account of all the species found in America, north of the equator, with keys for ready identification, life histories and methods of capture . hjust below lateral line, some of these forming reticulations enclosingpale spots; more than 20 black specks or mucous pores on base ofpreopercle, generally arranged in more than i row; belly and sidessilvery, but always with roundish dusky spots or cloudings in theadult; a black axillary spot. GENUS AUXIS CUVIERThe Frigate Mackerels Body oblong, plump, mostly naked posteriorly, anteriorlycovered with small cycloid scales, those of the pectoral regionenlarged, forming a corselet; snout very short, conical, scarcelycompressed; mouth rather small, the jaws equal; teeth verysmall, mostly in a single series, on jaws only; tail very slender, 276 The Frigate Mackerel depressed, with a rather large keel on each side; first dorsal short,some distance from second; second dorsal and anal small, eachwith 7 or 8 tlnlets; no air-bladder; gillrakers numerous, very longand slender. The only species of this genus is the frigate mackerel (^). This fish occurs in all warm seas. On our Atlantic. Coast it is seen occasionally as far north as Cape Cod. It ap-pears to be very erratic in its movements, and rarely reaches theUnited States coasts. It swims in large schools and sometimesappears in immense numbers. In the Adriatic it is called Tim-berello. It resembles in some respects the common mackerel; in othercharacters it resembles the bonito, the genus Aiixis being inter-mediate between Scomber and the related genera Pelamys andOrcyntis. It is not much valued as food. Colour, blue, variegated with darker above, becoming palerwith age; belly silvery. GENUS GYMNOSARDA GILLThe Little Tunnies This genus differs from that of the great tunnies in the ab-sence of teeth on the vomer, the complete absence of scalesoutside the corselet, and in the peculiar development, in theform of a network or trellis,
