PROCEEDINGS OF THE NATIONAL MUSEUM.. branchiostegal rays, preorbital and apex Leading forward to almost the extreme tip of the snout. A number of specimens 15 inches long obtained by Dr. Gilbert (Albatrosfi Collection) on Clarion Island of the Eevilla-Gigedo Group in Mexico.
Gill Rakers less, the starting points on the front i)art of the forelimb apparently forming a continuous spinulosus ridge.

Interorbitalspace, preorbitals, maxillaries, the rays of the dorsal, anal, and caudal fins, and the median rays of the pectorals, scaly. The pectoral organs are moderate, reaching a little beyond, the middle rays lv;ngest, 3iin length of the body; the bottom of the fin a little bit of path;. A small pale pink spot immediately below the base of the fourth spine, and another small immediately below the base of the eighth spine; a third larger spot just above the lateral line and below the ninth spine; a fourth place immediately below the first and a fifth place. below the last dorsal rays.
452 FISHES COLLECTED BY THE ALBATROSS— GILBERT
Color.-Brownish above, greyish below; head and front parts more or less distinctly vermiculated with dark olivaceous, these markings especially on legs or head; sides with (> to 15 narrow brown oblique bands extending downwards and backwards from lateral line about halfway to anal fin, this obsolete or less conspicuous anterior portion of body; both dorsals spotted with olive; caudal with 3 broad, black-kisli -bars not crossing the upper and lower rays, the last beam broad and very conspicuous icons; upper ray of caudal dark olive; no black spot base of caudal; anal andventrales white;. Head very large and broad, wider than the body; mouth large , vertical, a fringe of barbels curving over mouth on each jaw, their length a little greater than the diameter of the eye; .. tongue very large and fleshy, forming a cushion under the membrane of lower jaw, which somewhat projecting forward; teeth conical, small and movable, in many bands in the upper jaw: in the lower jaw the teeth are larger and in two or three rows; vomer and palatines with teeth. Eyes very small but prominent; interorbital very wide, four times as wide as the eye; bone sun top of head coarsely granular;.
-shaped crest on head prominent, with a wide bare area on each side; the shape of these and other bones of the head exactly as in A. y-f/ra'cvni; the ends of the nostrils are tightly closed; anterior nostril round, ridge between it .. and eye not very high or prominent; posterior nostril terminating in a long curved furrow which runs obliquely across the bare area behind the eyes; at its posterior end it turns strongly forward, its length 2| . how many times the diameter of the eye; two very short blunt spines in front of eye; surface of operculum, paraoperculum. and humeral process granular, not so rough as in A. ygrcecum; Gill rakers not developed; small pseudo-branching. Head completely scaleless; abdomen bare below line drawn from first ray .. anal to middle of pectoral base; fins without scales; scales small and nearly square, grown together side by side, forming oblique series. Width of base of chest slightly less than half length of head; .. fin isi) painted and slightly turned upwards, which predates in all from the base of the third dorsal ray; ventral rays thick and inflated, inner rays longest, reaching almost midway between base and apex of thorax; insertion of the abdomen into the front of the chest at a distance equal to the width of the pectoral base; soft dorsal somewhat higher than anal, its posterior rays reaching vertical from base of last anal ray; apex of last rays reaching base of caudal rays; caudal or slightly rounded cut; a fold skin along- .. midline of abdomen from ventralsto vent.
Color.— Dark brown above, lighter below; upper parts with numerous round white spots of various sizes, edged with dark brown rings .. spiny back black, light behind; soft backlight at bottom, ends of rays with black and white stripes; i) ectoral and anal dark with a light edge, caudal with longitudinal black and white stripes. This fish was distinctly electrocuted when alive, the electrical organs apparently being in the fleshy area on top of the head behind the eyes. Body slender, nioderatelj^compressed; dorsal profile forming an almost straight line from the back to the first dorsal ray, thence descending very gently to the base of the tail; ventral profile approximately straight.
Teeth present on both jaws, (;anine-like; onion)parcible with -S eidarged teeth in front, about 2 or 3 series of much smaller teeth behind, of which only 1 series extends into the posterior part of the mouth; lower, . jaw with a series of teeth in front and on the sides, which are greatly enlarged in front; a patch of very small teeth behind the enlarged one. No cirria upper eyes, nor filaments on the neck. Body covered with cycloid scales, those on the neck much smaller; belly naked. Lateral lines simple, straight, running from the upper edge of the gill opening to the last ray of the back when it disappears, without reaching the tail. Placed very high, and gradually approaches the dorsal fin, from which. it is only separated by a very small distance.
It extends dorsally from the tip a short distance behind the occiput almost to the base of the tail; the fin is marginal, with the last spine the shortest, about 2^ in the first soft strand, the latter 2^ in the head; longest dorsal spines about 3 in head, all spines slender and flexible. Ventrals well developed, inserted very slightly in front of base of sternum, with broad base, rays thick. It is the type of a separate genus {Emmfiion), somewhat related to Labrosomus and Pseudoblennius, and is chiefly distinguished by a straight dorsal lateral line terminating at the base of the last dorsal ray, a scaly body, and denticles.
456 FISHES COLLECTED BY THE ALBATROSS— GILBEIIT
Eyepiece large (young), 2|in head; snout short, depressed, not pointed, and with lateral keel, head with 5 fins. Mouth quite large, sloping, the upper jaw reaches below the front of the facade, L':| in head; lower jaw slightly longer, the tip with a stitisli pointed projection representing the barbell; teeth small, in bands, some on tip. small membranes somewhat united, free from isthmus. First dorsal rather low ami lonii, . none of his rays produced, the longest about half a head...mental, half a head; chest muscles about half head; caudal left. Head: Anally deeply notched behind the center, the posterior lobe highest.
Young specimen, 5.5 cm long, from Albatross station 2993, 364 fathoms, near Clarion Island of the Revilla-Gigcdo group, Mexico. Eye small, 5.5 cm long; interorbital area moderately prominent, narrow, about two-thirds of the eye length. Scales cycloid, small anteriorly and larger in size posteriorly, covering the head and cans; about 100 on the lateral line.
Origin of dorsally opposite anterior margin of eye; caudal end at an obtuse angle, not doubly concave; caudal pedunclewide. Body and parts colored with dark brown and pearly white spots and speckled with very dark brown spots, the spots more yellowish on the median, especially on the tail, where there are three lines of spots crossing the skin. It was then thought to be Pdralichthiis adspersus, from which species it differs but little, except in the number and length of the gill teeth.
