Sub-fam. Mustelinse.) Gen. Char.—Form tapering, moderately compressed. Five small gill-slits, the three anterior in front of pectoral. Two dorsals without spines, and moderate ventral and anal fins: caudal moderate, extremity of body scarcely elevated, a notch in distal lobe ; basal lobes moderate. Nostrils with a very long narrow triangular lobe from anterior edge, and a small lobe from posterior margin. Mouth moderately arched, with strong prominent cartilages and a deep fold about each angle. Teeth very numerous, small, rhomboidal, flat, like a tiled pave- ment, of many alternate rows ; the posterior rows in some species with a slight short median point, and one still smaller at one side. Spiracles moderate, a little behind and below the posterior corner of eye; eye elongate. A nictitating membrane. No pit in front of caudal. Scales very small, triangular, tricarinate. Cosmopolitan.] Description.—Head semi-oval, flattened, pre-oral portion about equal to the width of mouth. Eyes approximate, lengthened with a thick fold below, forming- the nictitating lid, their anterior edges about as far from tip of snout as from each other. Spiracle a little behind the eye. First dorsal small, entirely behind the inner posterior lobe of pectoral, or very slightly in front of it, a little nearer to snout than to the second dorsal; anterior and posterior bases of anal a little behind the corresponding parts of second dorsal; space between dorsals two and a half in length of the base of second dorsal. Tail very slightly elevated; notch in distal lobe of caudal fin deep and narrow. Color: Back and sides ashy-grey, with a slight pinkish-brown tinge on side of head and body ; with, from nape to second dorsal, very small lighter spots on back and sides above lateral line; lower lip, lower third of sides, whole under surface of body, and under side of pectorals and ventrals, milk-white; hind edge of dorsals and tip of caudal blackish; iris mottled green and brown bronze, darker above and below. Teeth in about seven rows, the inner angle slightly prominent as a very obtuse cusp on the inner rows. Measurements.
