Teeth small, conical, somewhat recur> >d, arranged in villiform bands. Origin of first dorsal to snout 4^ times its base, its distance from anterior margin of orbit much less than length of head; first spine very short, hardly perceptible above tho skin; second spine about 2 in head, slender and unarmed, when laid back its tip reaching to or beyond origin of second dorsal, the spines decreasing in length very gradually, the sixth being nearly as long as second, so that the fin is not so triangular as in If. hairdii', second dorsal beginning in a perpendicular from seventh anal ray; anal much higher than in M. bairdii, nearly e<|ual to ^ inter- orbital width, its origin under eighteenth scale of lateral line, its longest rays as long as interorbital width; distance of pectoral from snout equal- ing twice its own length, which about equals longest dorsal sjiine; origin of pectoral below middle of depth of body .and below level of middle of orbit, its tip not reaching origin of anal; insertion of ventrals behind ])ectoral, slightly in advance of first dorsal, its distance from snout greater than twice its length, the long filament not reaching anal.
