General form of Elacate,but the dorsal and anal fins are much shorter_, andthere are two ridges on each side of the tail^ at thebase of the caudal (a) ; before the dorsal a series ofdetached spines; scales small but hard^ deeply stri-ated (6), and crenated on the edges; mouth nearlyvertical ; lower jaw with a row of acute teeth, andothers in the palate and vomer : the cheloniform type ?T. Cuvieri Risso. Griff. Cuv. pi. 51. fig. Chorinemus Cuv.* Body elongated as in the mackerel, butthe general shape of the head and position of the dor-sal and anal fins as in Elacate ; mouth large, openingobliquely; gape reaching in a line with the eye;detached spines before the dorsal and anal; both finslong, falcate before and very narrow behind, wherethe ravs are detached into finlets; caudal lunate,without any carinated ridges at its base ; pectoralsmall, equal to the ventral; lateral hne maculatus Sw. Cuv. pi. 236. Forthmeus Cuv. Small, oblong-oval ; head pointed ;mouth very wide^ opening beyond the eye; lowerjaw much the longest; the chin rather pointed;dorsal spines connected at their base by a slight mem-brane ; pectoral and ventral as in the last; caudalforked ; preoperculum obsoletely argenteus Cuv. pi. 264. fig. 2. * This sub-genus bears a strong resemblance to that of Scomber proper,by the detached dorsal finlet
