Anal fin anteriorly nearly as high as the dorsal, its posterior rays low. The number of rays apparently I, 25, possibly I, 24 or I, 26. Ventral fins totally obliterated. Pectoral fins placed low, rather short, about as long as the maxillary. Caudal fin short, narrow, apparently forked.

The coloration is apparently light olive, the sides silvery, with dark punctulations. Fins plain. Peritoneum silvery, underlaid by black pigment.

This species differs from Sudis hyalina as described by Dr. Günther (Cat. Fishes Brit. Mus., v, 420) chiefly in the dentition, canine teeth. being present on the premaxillaries and palatines, as well as on the mandible. The head is also shorter and the mouth apparently larger in proportion.

Myctophum crenulare, sp. nov.

Form much compressed, deepest in front of the base of the pectorals, bluntly convex anteriorily, tapering behind. Ventral region much more arched than dorsal. Caudal peduncle long and very slender. Head short and high, abruptly rounded in profile, the snout very blunt. Jaws equal, the snout not projecting beyond the mouth. Maxillary very slender, scarcely widened to its tip, and not dilated, its extremity reaching beyond the eye to the margin of the preopercle.

Premaxillaries anteriorly on a level of the pupil. Teeth very small, present on all the dentigerous bones. Rami of the mandible nearly par allel, coming together in a sharp keel below.

Orbital margin above and in front with a thin membranaceous rim, that in front distinct and formed by the upturned edge of the preorbital. Nasal bones membranaceous, their edges upturned, forming a horizontal

groove. A groove between the frontal bones. Orbital margins separated by a groove from the preopercle. Margin of preopercle very oblique. All the membrane bones extremely thin, membranaceous. Eye large, 33 in head. Gill-rakers long and slender. Head 33 in length to base of caudal; depth 44.

Head and body completely covered with thin membranaceous scales, those on the middle of the sides not elevated and not noticeably larger than the others. Free edges of all the scales crenulate, some of them, especially on the back, with the crenations acute, but without spines, the scales not being really ctenoid or spinous. About 45 scales in a longitudinal series.

A phosphorescent spot on each mandible near the symphysis, 33 pairs of spots along the belly, 6 in front of ventrals, 6 between ventrals and origin of anal, and 21 between front of anal and base of caudal.

Caudal peduncle above and below with two or three backward-directed spines, which are apparently the exserted tips of vertebral pro

cesses.

Fin rays (not quite certain, the tips being frayed out): Dorsal about 12, anal about 16, the fins rather low.

Origin of dorsal nearer the snout than the base of caudal, much behind the base of the ventrals. Ventrals short, not reaching half way to vent. Pectorals reaching base of ventrals.

Color very dark steel-blue above, silvery on sides and below, with dark metallic luster. The usual phosphorescent spots present, as above described. No evident cream-colored blotch on the back of tail.

Myctophum crenulare is known to us at present from a single specimen, about 1 inches long, taken from the stomach of an Albicore (Orcynus alalonga) in Santa Barbara Channel, July 11, 1880. It had evidently just been swallowed, and is in fairly good condition.

It belongs to that division of the genus "Scopelus" called by Dr. Günther" Myctophum" (Cat Fishes Brit. Mus., v, 405). As the latter name has priority over Scopelus, it must be retained as a generic name for some or all of these fishes.

DESCRIPTION OF TWO NEW SPECIES OF FLOUNDERS (PAROPHRYS ISCHYRUS AND HIPPOGLOSSOIDES ELASSODON,) FROM PUGET'S SOUND.

By DAVID S. JORDAN and CHARLES H. GILBERT. Parophrys ischyrus, sp. nov.

Body rhombic-oblong, less deep than in Platichthys stellatus or Lepidop setta bilincata, and with the head more pointed and protruding, but less so than in Parophrys vetulus. Body tapering from the middle to the head and tail, the four bounding lines but little curved and quite regu lar. Caudal peduncle strong, compressed, and rather long. Head comparatively long, a slight angle over the eye, and the snout protruding and not obtuse. Lips full, simple. Mouth moderate, oblique, the lower jaw slightly projecting and somewhat more developed on the blind side, 5 + 25 Teeth about in number. 10+ 22

Teeth in one series, rather close set, some on both sides of the jaw. but more numerous on the blind side, somewhat irregular in length, some of them movable. In form the teeth are somewhat compressed and incisor-like and bluntish, but not as notably so as in some related species. No teeth on vomer and palatines.

Maxillary reaching past the front of the orbit, nearly to the pupil. Anterior nostril with a flap. Posterior nostril almost simple. Tongue free. Eyes rather large, the upper directed upward, the lower slightly in advance of the other. An area covered with smooth skin in and be hind orbit of upper eye.

Interorbital space rather broad, somewhat elevated mesially, continuous, with a slightly marked ridge above the opercle and forking forwards, the lower branch ending in a blunt prominence.

Snout behind nostrils, interocular ridge, and posterior part of head covered with scales like those on the body, but smaller and rougher. Preorbital very narrow, naked. Skin of head continuous over the edge of the preopercle. Gill openings above not continued forward. Gillrakers short, slender, and weak, about 12 below the angle of the arch. Branchiostegals seven. Lower pharyngeal bones separate, each with two rows of coarse, blunt teeth.

Scales moderate in size, thick and firm, adherent, not closely imbri cated, anteriorly separated. Those on the tail oblong and a little im

bedded, those on the head and anterior regions rather regularly arranged, but not close together.

Scales strongly ctenoid everywhere, each with a semicircle of six to ten upward-directed spinules on its posterior edge. Those on the head and body are similar, the former being a little smaller and rougher, especially behind the eyes, where they are somewhat stellate.

Left or blind side of the body uniformly scaled like the eyed side, the scales similar and almost as strongly ctenoid. Preopercle nearly smooth. Rest of head with small rough scales, similar to those on the right side, but farther apart.

Caudal, middle part of dorsal and anal, and bases of pectorals and ventrals with small rough scales in series, running up the rays on the right side. On the blind side the base of the caudal with small rough scales. Other fins naked.

Lateral line conspicuous, its scales less rough than the others; a very slight curve anteriorly, otherwise straight. A distinct short accessory lateral line on both sides, extending to about the tenth dorsal ray. A series of pores around lower eye behind. No enlarged scales along lateral line or at the bases of the fins.

Lateral line with about 88 pores; about 80 scales in a longitudinal series above the lateral line.

Dorsal fin beginning over the pupil, its first rays turned slightly toward the blind side, low in front, the rays regularly increasing to behind the middle of the body,then similarly diminishing. Anal fin similarly formed, preceded by an antrorse spine. Highest rays of dorsal and anal about equal and nearly half the length of the head.

Caudal fin large, somewhat double-truncate, the middle rays produced Pectoral a little more than half the length of the head, that on blind side shorter. Ventrals reaching to anal. Rays of dorsal and anal all simple.

Dorsal rays, 70-76; anal, 52-57; ventrals, 6. Eyes and color on the right side.

Color above light olive-brown, vaguely clouded with light and dark Fins reddish-brown; a few roundish dusky blotches on dorsal and anal, resembling in position the black vertical bars found in Platichthys stel. latus. Pectoral and caudal tipped with dusky. Blind side white, either immaculate or else with small round rusty spots. Left side of head sometimes rusty tinged.

This species is known to us from four examples obtained with a seine in the harbor of Seattle, Washington Territory. We place it temporarily in the genus Parophrys, inasmuch as it has the technical characters at present assigned to that genus, i. e., the small mouth with blunt uniserial teeth, and the straight lateral line with its accessory dorsal branch. The character of cycloid scales assigned to Parophrys needs modification, as in Parophrys vetulus most of the scales on the cheeks and tail are slightly ctenoid.

It is, however, evident that there is no special affinity existing between the present species and Parophrys vetulus, and no very close relation between either and Lepidopsetta isolepis Lockington, which, by its technical characters, would be also a Parophrys. The nearest natural ally of Parophrys ischyrus is perhaps Lepidopsetta bilineata, and the present arrangement is to be accepted only until the relations of these forms can be more fully investigated.

Hippoglossoides elassodon, sp. nov.

Body oblong-elliptical, strongly compressed, the dorsal and ventral outlines regularly and pretty strongly arched. Caudal peduncle moderate, about as long as deep and growing wider behind.

Head rather large, bluntish, its upper profile continuous with the outline of the back. Depression over the eye slight. Mouth comparatively large, very oblique, the upper jaw somewhat concave in outline, the lower correspondingly convex, the gape considerably wider on the blind side than on the right side. Lower jaw rather strongly protruding, with a considerable symphyseal knob. Maxillary rather narrow, reaching to opposite the middle of the pupil or beyond, the maxillary on the blind side much longer than the other. Premaxillary anteriorly on the level of the interocular space.

Upper jaw with a single series of small conical teeth, which are not very sharp. These teeth are somewhat larger in front than on the sides, and also more widely set. Everywhere they are quite small, much smaller than in Hippoglossoides jordani, and not larger than in H. exilis. Lower jaw with a single series of rather close-set teeth similar to those in the upper jaw, or slightly larger; those on the sides smaller than the 35 + 45 anterior teeth. Number of teeth about

25+ 35'

Eyes large, nearly even in front, the upper eye directed somewhat upward, but not reaching the dorsal line. Interorbital space a narrow sharp ridge, with about two rows of minute scales; 10 to 15 rows of scales in an oblique series on the cheeks. A series of mucous pores around lower eye behind. Preorbital narrow. Anterior nostril with a rather long flap, posterior with a slight tube

Gill-rakers long, slender, and straight, 15 to 17 below the angle of the arch, their inner margins feebly dentate. Pyloric cœca 4.

Scales small, firm, less readily deciduous even than in H. jordani, rough to the touch, with the spinules short and firm. Scales on head similar, but more imbedded, those on the tail larger and rougher

Scales on blind side small, mostly smooth, except on the caudal pedun cle, where they are larger and rough ctenoid, like the scales on the right side. The scales along the base of the dorsal and anal and those near the lateral line more or less ctenoid. Scales along left side of head small, non-imbricate, those on the preopercle and posterior part of the cheeks becoming obsolete. The amount of roughness on the scales below is subject to considerable variation.
