dorsal behind vent; second dorsal inserted before posterior end of base of anal.

Caudal not lunate. Skin very rough, densely covered with prickles, each with a long

central cusp and a pair of short lateral cusps. Scales on the upper edge of tail

behind second dorsal scarcely enlarged.

Color in formalin reddish brown, with some irregularly scattered, whitish round

spots and dark brown blotches with similar spots ; these blotches may form transverse

large-meshed bands by uniting with one another. A\ll the fins, except anal, are colored

and marked like the body; anal dusky, without distinct markings. Under surface

pale.

with a deep notch between. Anal low, falcate. No tail filament. Six rods in the

anterior lamina of upper jaw; lateral rods behind the»lamina low, oblique. Each

lamina of lower jaw with two concavities more or less sinuate in the margin. Cephalic.

organ on the snout in front of eye, its inner surface armed with about seventy spinous

denticles. Claspers tripartite. Anterior ‘ventral clasper with five spiny denticles on

the median side. Lateral canal with fine sinuations ; jugular branch arising directly

from the suborbital a short distance behind the maxillo-mandibular.

Color in formalin dark brown with lighter dot-like and elongate spots, often

indistinctly vermiculate owing to fusion of spots. On the side of body behind the

ventral three pale broad lines below the lateral canal and one above it. Dorsals, anal,

caudal as well as free margins of pectoral and ventral blackish.

Described from a male specimen, the type, 62 cm. long as measured to tip of

Tail slightly longer than head and trunk; head rather short, moderately com-

pressed ; eye midway between tip of snout and angle of mouth ; anterior nostril tubular,

half as long as diameter of eye ; posterior nostril without tube and very close to eye. Jaws equal, completely closed, with uniserial pointed teeth ; upper jaw with ten teeth on each side, of which the anterior ones are much larger ; lower jaw also with about ten teeth on each side ; none on vomer. Mouth-cleft extending backward from eye more

than the diameter of latter ; gill openings slightly shorter than diameter of eye.

Color in formalin reddish brown, rather profusely adorned with whitish spots ; the

Same maculation on the under surface. The largest spots are half as large as eye in diameter and sometimes larger than the interspaces ; posteriorly the spots are smaller

and more distant ; inside of mouth similarly spotted ; angle of mouth, gill-opening and

vent without special coloration. Dorsal fin spotted anteriorly but plain posteriorly ;

Anal entirely without spots ; both vertical fins narrowly edged with whitish.

of both fins adnate to base of caudal ; tip of rays of both fins extending far beyond base

g, some of them bifurcated posteriorly, but the length of of caudal. Caudal rays long,

the branches can not be measured owing to the bad state of preservation. Three

dorsal caruncles perforated at tip, at a short distance in front of dorsal rays ; the median

caruncle largest, at about one-fifth head length in front of the insertion of dorsal;

lateral caruncle about one-third the median in size and slightly more advanced. Skin

covered throughout with fine shagreen ; eyes and the groove for the cephalic tentacle

are the only naked areas of the body surface.

Color in formalin jet-black ; all fins and appendages, inner surface of mouth and

gill-opening similarly colored. Terminal fringe of cephalic tentacle whitish, bulb

blackish.

The type (No. 21251, Alan Owston’s Collection) is the only specimen known.

It is 44 cm. long as measured from tip of snout to that of the longest caudal rays.

Upper lobe of caudal slightly higher than the lower ; second dorsal continuous with

caudal with a deep notch between. Caudal filament rather long. Anal very low,

falcate, continuous with the lower lobe of caudal, but with a deep notch opposite the

dorsal one, and similar to but deeper than that of Chimera phantasma. Pectoral

pointed, facate ; its tip reaches far behind the insertion of ventral when depressed.

Teeth confluent ; five or six rods in each anterior lamina of the upper jaw ; the margin

of the lamina sinuate and slightly convex ; lateral rods behind the anterior lamina low,

oblique, their tips directed toward the median line. Mandibular laminz included

within the upper laminze; rods in the laminz rather indistinct, margin of lamina with

two concavities and more or less indistinctly sinuate. Cephalic organ on the snout in

front of the anterior margin of the eye; with about sixty or more recurved spinous

denticles on its lower side. Claspers tripartite, its tip covered with fine shagreen as

usual ; its length from the insertion 12 in head ; the division occurring at two-thirds of

its length from the base, as in Chimera owstoni (see plate V, fig. 18). Anterior

ventral clasper armed with five spinous denticles on the inner side. Lateral canal

straight, almost without any sinuation. Jugular branch arising from the suborbital a

short distance behind maxillo-mandibular.

portion elevated ; ventral contour nearly straight ; caudal peduncle short, rather small,

slightly depressed ; tail a little bent upward. Head moderate in size, depressed ; eye

oblong, lateral, high up, nearer first gill-opening than tip of snout, with nictitating

membrane ; interorbital wide, broadly convex ; snout rather short, pointed ; spiracles

rather small, oblong, directly behind eye. Mouth inferior, obtusely angular ; tip of

mandible not entirely before eye; lips thin; labial fold distinct ; teeth in both jaws

subequal, rhombic, pavement like, middie of each tooth somewhat elevated, number

of teeth rows in upper jaw about thirty five, in lower jaw about thirty eight. Nostrils

well separated from each other and mouth, nearer anterior tip of upper jaw or eye than

tip of snout or angles of mouth. Gill openings five in number, subequal, equidistant,

last one entirely above pectoral, but penultimate one very close to anterior tip of base

of pectoral. Two dorsals without spines, concave in the upper border, similiar in

shape; First dorsal larger than the second, nearer anterior end of base of ventral than

outer end of base of pectoral and also nearer second dorsal than tip of snout ; second

dorsal nearer root of upper caudal lobe than anterior end of base of ventral and also

much nearer the former than to first dorsal. Anal similar to second dorsal in shape, but

smaller, first two-thirds of its base before posterior end of base of second dorsal.

slightly nearer root of caudal than to origin of first dorsal, the outer margin emarginate,

its second ray longest. Anal a little larger in size than, but similar in form to the

second dorsal, its second soft ray below origin of the latter fin. Pectorals lateral,

from each other, inserted below end of two-thirds of length of pectoral, not extending

halfway between its origin and vent ; vent directly in front of anal. Caudal emarginate.

Scales ctenoid ; no lateral line, but the furrows are deepened at the middle of each scale

so as to form lateral streaks ; preorbital scaled.

Erratum to vol. II. (Issued Oct. 15, 1911.)

There is now no doubt that Hemzrhamphus elongaius described as new in vol. II

(p. 22) of this monograph 1s identical with Lz/eptorhamphus longirostris (Cuvier), as

suggested by President David Starr Jordan of Stanford University and Mr. David G.

Stead, naturalist to the Board of Fisheries for New South Wales, to both of whom I

am deeply obliged. The name and synonyms must therefore be corrected as

follows :—

downward, and disappears abruptly; the third in front of dorsal going on downward

and forward disappears nearly in level with end of the second band; the fourth form-

ing a saddle above the caudal peduncle runs a short distance downward and forward

in a more pronouncedly oblique direction. four narrow short bands radiate backward

from posterior rim of eye. Body with reticulation of pale color, this being most dis-

or palatines ; no barbel about mouth; gill-openings small, in a level with eye, oper-

cular flap slightly pointed. Two dorsals well separated, the first rather hidden in the

skin. Ventral disk rather large, much longer than wide, its length 12 in the length

of head measured as above. Body thickly covered with large tubercles which are armed

with small projections on the sides and base ; interspaces between the tubercles very

narrow and entirely naked ; largest tubercles on the sides of body above pectoral ; those

on head much smaller, and those on chin and caudal peduncle still smaller; narrow

posterior part of head, axil of pectoral, and small space immediately posterior to the

ventral disk entirely free from tubercles ; basal part of all the fins with a few small

tubercles. Color dark reddish yellow, paler below; all the fins pale.

Described and figured from a dried specimen 9.2 cm. long as measured to tip of

caudal, obtained about Niigata, Prov. Echigo, by Mr. Yamaguchi.

Cyclolumpus, the new genus with Cyclolumpus asperrimuts as type is defined as

follows :

Body somewhat oblong, closely covered with large tubercles all over except fins,

narrow posterior part of head, axil of pectoral etc.; ventral disk smaller than in Ay7-

crotremus, a Closely allied genus.

without median tooth ; eye without nictitating membrane ; spiracies distinct, at some

distance behind eye ; gill-openings five in number, narrow, entirely in front of pectoral.

‘Two dorsals, without spine in front ; first dorsal larger than second, inserted almost midway between pectoral and ventral ; second dorsal just behind ventral; no anal ;

upper and lower lobes of caudal well developed, with a slight notch between. Body

uniformly covered with minute scales.

The genus differs from the allied genus, fLuprotomicrus, in having first dorsal

108 Eleotris.

Color in formalin blackish brown, lighter below; several narrow longitudinal,

darker bands faintly visible; no distintt lines running from eye; dorsals and anal

paler, each with several rows of backish spots’and pale free margin ; pectoral and caudal

pale, each with numerous vertical rows of blackish spots ; ventral dusky, with cross

rows of faint blackish spots.


taken in River Tansui near Taihoku, Formosa, by Mr. Akamatsu.

The species is closely allied to Eleotris oxycephala (Temminck and Schlegel), but

differs from it in having a much more robust body and head, much smaller scales,

much more convex interorbital, and in having more scales in transverse series.
