This small species, for it seldom exceeds five inches in length, agrees in the general characters of the genus; 
but is distinguished by the length of the first ray of the second dorsal fin, which measured nearly two inches; 
the first dorsal consists of seven soft spines; there is a recumbent spine in front, and the appearance of several 
others under the skin, as in No. CXLIV. and CXLVI. The dorsal and anal fins in grooves; the second com¬ 
posed of rays and pinnulae united. The pectoral long, falcate; the caudal bifid, the lobes lanceolate. 
The mouth nearly middle; the lips and cheeks membranous, white, pellucid; the jaws extractile, but the 
upper capable of wider extension than the under, raising the rostrum along with it, which returns to its place 
when the mouth shuts. Teeth linear. 
The colour. The crown, pale-green; the face and trunk, mother-of-pearl; the rest silvery white. The fins 
yellowish. 
Length of the subject, five inches and a half. 
No. CLII. 
Scomber pinmdis dorsalibus unitis quatuordecem ; cauda bifida; pectore alepidoto , prominente; 
spinis ante pinnam dorsalem nullis ; pinnula prima anali carens. 
The Scomber with fourteen united dorsal pinnulae ; a bifid tail ,* a prominent, naked, 
breast; no spines in front of the dorsal fin ; and no first anal fin.

This agrees with the species last described in the structure and motion of the upper jaw, the membranous 
cheeks, the linear teeth, and the form of the dorsal, anal, and caudal fins; but it differs in other respects. 
The body in the fore part, is broader, and rounder; the hind part, from the beginning of the second dorsal and 
anal fin, trigonal; the abdomen straight and flat; there is no recumbent dorsal spine; the biradiate anal fin is 
wanting; the first dorsal has only five spines; and the branchial membrane six rays. The pectoral fin in both 
is long and falcate; but the ventral are remarkably long and setaceous, with only five rays. In the opercula, 
smooth tongue, palate, and branchiae, they agree. The lateral line undulates a little above the pectoral fin. 
The colour, to the best of my recollection, was much the same as that of the species last described; but the 
only circumstance noted in my memoranda, is, that the iris was silvery.
