JAPANESE FISHES. 
623 
Head, 3.5 in length; depth, 2.66; length of upper eye, 3.75 in head; snout from upper eye, 4.66; 
pectoral of eyed side, 2.1; pectoral of blind side, 3; ventral, 3; length of middle dorsal rays, 2.16; 
middle anal rays, 2.16; caudal, 1.4; interorbital space narrower and more concave than in adult; 
color light, with fine points scattered over a flesh-colored ground, these following more especially 
the outline of scales; indefinite dark brown spots scattered over body; one always present on 
lateral line at beginning of posterior third; one or two usually placed irregularly along lateral line 
anteriorly; a few following dorsal and ventral outlines of body; fins light, mottled with grayish brown. 
All of our numerous specimens were dredged off Kinkwazan Island, Matsushima Bay, at stations 
3769 and 3770. The type is 22 cm. in length, No. 51403, U. S. Nat. Mus. ; cotypes are No. 8391, Stanford 
University. 
110 . Xystrias grigorjewi (Herzenstein) . 
Hipjmglosms grigorjewi Herzenstein, Bull. Ac. Imp. Sci., Petersb. , 1890, p. 134. 
Verasper otakii Jordan & Snyder, Proc. U. S. Nat. Mus., xxm, 1901, p. 378; Tokyo. 
A large specimen, taken at station 3699, Suruga Bay, in 400 to 726 fathoms. 
This species differs from others referred to Verasper in having long, slender gillrakers, the scales 
all cycloid on blind side, and those of eyed side more finely ctenoid; spinules more even and numerous. 
It may be made the type of a distinct group or genus, called Xystrias, from the long gillrakers. 
111 . Pleuronichthys cornutus (Schlegel). 
Two specimens taken in Suruga Bay, station 3708, off Ose Point, in 65 to 125 fathoms, and station 
2356. A larva with the eyes still symmetrical perhaps belongs to this species. 
112 . Iiimanda herzensteini Jordan & Snyder. 
IHeuronectes japonicus Herzenstein, not of Houttuyn. Limanda herzensteini Jordan & Snyder Proc. U. S. Nat. Mus., 
xxm, 1901, p. 746, after Herzenstein. 
One specimen dredged in Matsushima Bay, station 3768, 25 cm. in entire length, differs from 
Herzenstein’s description in having 84 series of scales (88 pores). Others collected by Jordan & Snyder 
at Tsuruga, Matsushima, Hakodate, and Aomori have from 80 to 85 scales. 
AL7E0PS Jordan & Starks, new genus. 
Alseops Jordan & Starks, new genus of Pleuronectidx (plinthus). 
Allied to Pcecilopsetta, but with large ctenoid scales which are somewhat caducous. Eyes and color 
on the right side. Lateral line simple, with a broad flat-topped arch in front; mouth moderate; teeth 
small, in bands. Gillrakers short and sharp. 
113 . Alseops plinthus Jordan & Starks, new species. (PI. 5, fig. 2.) 
Head 4 in length; depth 2.4; D. 61; A. 53; scales 65 (pores); upper eye 3 in head; snout from 
upper eye, 4.16; maxillary 3.16; pectoral of eyed side 2.25; ventral median; caudal rays 1. 
Anterior body outline strongly arched above; orbital rim of upper eye protruding beyond rest of 
profile; snout a little produced, blunt; anterior nostril in rather broad, short tube, which does not 
reach to edge of preorbital; maxillary curved, reaching to below or very slightly past anterior rim of 
pupil of lower eye; teeth small, in a very narrow band on eyed side, growing wider anteriorly, some- 
what smaller on premaxillary. On blind side the teeth on both jaws are in moderately wide bands. 
Eyes equal in size, the lower slightly more anterior, separated by a narrow naked ridge; vertical limb 
of premaxillary short; gillrakers short and rather sharp, the longest one-half to one-third diameter of 
pupil, 5+10 in number; caudal peduncle very wide and flat, its length one-third of its width; scales 
large, rather finely but very evidently ctenoid on eyed side, cycloid on blind side; head on eyed side, 
anterior to posterior rim of pupil above, and posterior end of mandible below, without scales; lateral 
line turning abruptly upward at a sharp angle two-thirds the head’s length behind head, and forming 
a conspicuous flat-topped arch, as high as half length of head; dorsal beginning slightly on blind side, 
a little behind middle of eye, length of first ray contained 1.1 in upper eye, longest lavs near posterior 
end of fin, the longest 2. 25 in head; pectorals equal in size; caudal broad and pointed behind; no 
lateral angles, the sides broadly rounded from tips of the long median rays to lateral edges of fin base. 
Color pinkish slaty-brown, usually mottled with black; 2 inconspicuous semiocellated spots, one 
near dorsal and one near anal base a head’s length anterior to base of caudal; less conspicuous dark 
irregular spots along side above anal and below dorsal, one below arch of lateral line; a black spot on
