Hist. 1861, 133 {nomen nudum): tyj}Q Embiotoca carji L. Agassiz.) Body oblong, compressed, moderately elevated, tapering abruptly to a very slender and short caudal peduncle. Head moderate, rather acute, lower jaw included. Lips moderate, the lower with a frenum. Teeth few, conical, blunt, in one series, those of the upper jaw some- times partly in 2 series. Gill-rakers slender, rather short. Pharyn- geals normal. Dorsal fin rather low, the spines all lower than the soft rays. Caudal broad and short, iVidely forked. Anal fin extremely short, although many rayed, beginning far back, the length of its base being less than half the distance between its first spine and the root of the ventrals, the abdomen being therefore extremely long. Scales rather small. Vertebrje 17 + 20. This genus is distinguished from Ditrema chiefly hy the great length of the abdominal region. Species of
