BULLETIN OF THE UNITED STATES FISH COMMISSION. 
even, the upper encroaching on the profile; head without spines or tubercles; mouth small, oblique, 
with equal jaws; length of maxillary less than 0.3 length of head; teeth slender, villiform, arranged in 
wide bands in jaws; more numerous on blind side, where the bands are wider and longer; on eyed 
side, the bands taper rapidly, becoming single series in upper jaw, soon disappearing in lower jaw; 
vomer and palatines toothless; gill-rakers very short, toothless, developed on both vertical and hori- 
zontal limbs of arch, 8 + 12 in number. 
Dorsal fin beginning above middle of upper eye, extending, like the anal fin, to base of outer 
caudal rays; dorsal and anal rays all simple, scaleless, low, none of them prolonged; caudal double- 
truncate; the right pectoral longer than the left, its rays densely covered with series of scales; ventrals 
nearly symmetrical, with narrow bases, the right slightly in advance of the left. 
Scales rough-ctenoid on the right side, smooth and cycloid on the left; lateral line developed on 
right side only, with a high anterior arch, which is obliquely truncate above, its upper line nearly 
straight and rising posteriorly. 
Color in spirits, light olive-brown, with very fine brown spots and some faint dark spots and bars, 
the spots apparently arranged in a series just within upper and lower outlines, the bars apparently 
4 in number, with ill-defined edges, narrower than interspaces; a series of brown blotches on basal 
portion of dorsal and anal fins; right pectoral narrowly black-edged; caudal with a pair of large black 
spots occupying middle of outer rays. 
In 6 specimens, which do not include the type, the following fin and scale counts are observed : 
Dorsal 62, 64, 65, 65, 66, and 67; anal 53, 57, 55, 56, 58, and 58; pectoral 9, 10, 12, 11, 10, and 9; scales 
85, 84, 97, 84, 84, and 90. 
The species was taken at the following stations: Nos. 3832, off the south coast of Molokai, 142 to 
153 fathoms; 3858, Pailolo Channel, 128 to 138 fathoms; 3957, near Laysan, 173 to 220 fathoms; 4079, 
off the north coast of Maui, 143 to 178 fathoms; 4080, off the north coast of Maui, 178 to 202 fathoms; 
4081, off the north coast of Maui, 202 to 220 fathoms; 4082, off the north coast of Maui, 220 to 238 
fathoms; 4120, off the northwest coast of Oahu, 167 to 216 fathoms. 
Taeniopsetta, new genus. 
Body sinistral; ventral fins lateral in position, nearly symmetrical; mouth small, teeth small, 
conical, equally developed on both sides, in single series; scales minute, strongly ciliated in the typical 
species; a strong anterior arch to lateral line; no lateral line on blind side; a narrow sharp interocular 
ridge in both sexes; some of anterior dorsal and anal rays prolonged and filamentous. 
In addition to the typical species, the genus may include Pseudorhombus ocellatus Gunther (Shore- 
fishes, Challenger, 1880, p. 56, pi. xxiv, figs. A and B) , from the Admiralty Islands, although in this 
species the scales are said to be not ciliated. 
Taeniopsetta Gilbert, new genus of Pleuronedidx ( radula ). 
Taeniopsetta radula, new species. Fig. 266. 
Type, a male, 115 mm. long, from station 3858, Pailolo Channel between Molokai and Maui, depth 
128 to 138 fathoms; type, No. 51639, U. S. Nat. Mus. 
Length of head 26 hundredths of total length without caudal; length of snout from lower eye 5.5, 
from upper eye 9; diameter of upper eye 9; length of maxillary 7.5; depth of body 62; least depth of 
caudal peduncle 10; longest dorsal ray 43 (27 in female cotype); longest anal ray 45 (30 in female); 
longest non-filamentous dorsal ray 13; longest caudal ray 22; longest pectoral ray 16; chord of arch of 
lateral line 15. D. 88; A. 72; P. 13; pores in lateral lines about 110; rows of scales running upward and 
forward above lateral line about 140. Vertebrae 9 + 31. 
Body deeply ovate; ventral outline more arched than dorsal; snout very short, its anterior profile 
nearly vertical, very slightly incurved opposite origin of dorsal fin; eyes large, separated by a sharp 
scaleless ridge, which bears a series of spinous prickles, more or less numerous in both sexes; one Or 
more spines also present on the anterior rim of each orbit, one above premaxillaries, and one at sym- 
physis of lower jaw; lower eye but little in advance of upper; mouth very small, oblique, maxillary 
not nearly reaching vertical from front of pupil, about .3 length of head; teeth close-set, conical, equal, 
in a single series, with a few declined teeth forming an inner series in left premaxillary near angle of 
mouth ; vomer and palate toothless ; gill-rakers nearly obsolete, but 5 very short rudiments on horizontal 
limb of arch.
