Greatest depth of body, below origin of first dorsal, in length of head; greatest width, across' pectoral bases, ; the depth, at a distance behind snout twice the length of head, is contained only twice in the postorbital length, and is about 3 times the width of the tail at the same point. The sides of the head are convex; the snout is heavy and broad; its preocular length is contained times in length of head; it preoral length, times; its width at base, times; the width of the snout at anterolateral angles is a little less than the length anterior to that point. The in- fraorbital, occipital, supranarial, supraorbital, and postorbital ridges are exceedingly strong and heavily spined. The preopercular ridge and margin are oblique; the sharply pointed flap of the subopercle, concealed by the produced lobe at the angle of the preopercle, is. W$^§§« Fig. 30.—Coelorhynchus spinifer. Type. directed downward and backward, and is almost as long as the pupil. The orbit is oval and small; its length is equal to the least interorbital width, and is twice the least distance between the occipital ridges; orbit in head, in snout, in postorbital. Least suborbital width, in postorbital. The upper jaw extends from below the posterior nostril backward to below the hind margin of the pupil; its length is contained times in the head. The barbel is slender and very short, being contained times into the postorbital. The teeth are in rather narrow bands in the jaws; there are only about three teeth in a cross section of the mandibular band laterally. Six branchiostegals. Distance between isthmus and base of ventral, in distance from base of ventral to center of anus, in postorbital length. There are no naked areas on the breast. The scales are large, being in 4^ rows from the origin of the se
