Isopsetta, LorKiNGTON MS., in Jordan & Gilbeut, Synopsis, 832,1883 (isolepii). Body much compressed, elliptical in form; mouth rather large; the teeth chiefly uniserial, all more or less hluut, separated, not inciBor-like; scales closely imbricated, all strongly ctenoid; lower pharyngeals each with a double row of bluntish teeth. A single species found on the coast of California. Jsopaetta approaches in many respects very close to the large-mouthed flounders of the type of Hi^pogloaaoidca, and it may fairly be said to be intermediate between Fsettichthya .and Lepidopsctta. Its aOinities on the whole are nearest the latter, but the close of the llippogloaxina! and Pleuronectinw is clearly shown, (i'doi, equal; ipffrra, flounder.) soil. ISOPSETTA I$(»LEPI8 (Lockington). Head 4; depth 2^. D. 88; A. 65; scales 88; vertebra; 10 + 32 = 42. Body elliptical, much compressed, moderately deep, the curvature very regular; head moderate, strongly compressed, the prolile little depressed above the eye; eyes rather large; interorbital space broad, flattish, with several series of scales. Scales on cheeks similar to those on body, rather large, ctenoid, and closely imbricated. Mouth comparatively large, maxillary reaching pupil, 3| in head; teeth not large, about .jxiu, conical, close set, in 1 somewhat irregular series, or partly in 2 series, those on colored side small; lower pharyngeals each with a double row of bluntish teeth. On the blind side the scales are more or less ctenoid, sometimes smooth; those on the cheeks weakly ctenoid; most of the opercle, the pn^operde, interopercle, and subopercle on blind side naked; lateral line with a very
