FISHES OF HAWAIIAN ISLANDS. 
637 
The species of Txnianotus have been very insufficiently described and figured. It is by no means 
evident that all the specimens listed as Txnianotus triacanthus Lacepede are conspecific. Gunther’s 2 
figures (Fische der Siidsee, I, pi. 57, figs. A & B) differ widely in other respects besides color, and 
must, if correct, represent more than one species. It is impossible to identify T. citrinellus with any of 
these, or with T. garretti Gunther, the latter from the Hawaiian Islands and described from a colored 
drawing only. It is represented with very broad, short pectorals, strong cephalic spines, and very 
short anal spines, and differs in many other important details in addition to the color. 
Dendrochirus barberi Steindachner. 
One young specimen from station 3849, off the south coast of Molokai, depth 43 to 73 fathoms. 
Family BEMBRM. 
Bembradium, new genus. 
Related to Parabembras, from which it differs in having much larger scales, a lateral line running 
near middle of body (as in Bembras), not parallel with the back, and a short mandible included within 
the upper jaw. 
Bembradium Gilbert, new genus of Bembridx ( roseum ). 
Bembradium roseum, new species. Plate 82 . a 
Type, 90 mm. long, from station 3859, Pailolo Channel, depth 138 fathoms; type, No. 51617, 
U. S. Nat. Mus. 
Head 40 hundredths of total length without caudal; depth 18; width of snout 14; length of snout 
13 (to front of eyeball); eye 11; interorbital width 2; maxillary 18. D. ix-12; A. 11; Y. i, 5; P. 25. 
Lateral line 28; 3J horizontal series of scales above lateral line. 
Body elongate, gently compressed along dorsal region; head narrow, depressed, with long snout; 
lower profile perfectly straight from tip of snout to tail, upper profile gently and evenly curved, highest 
under spinous dorsal; mouth horizontal, lower jaw shorter than upper and included within it when 
the mouth is closed, maxillary reaching slightly beyond front of pupil; teeth uniformly minute, 
forming narrow bands in jaws and on vomer and palatine bones; interorbital space a very narrow 
groove, the raised margins of which are minutely serrate with backwardly directed teeth; they are 
nearly parallel, diverging gently forward and continuing to middle of length of snout, and diverging 
posteriorly more rapidly, not continuing behind line of orbits; a strong triangular backwardly directed 
spine immediately in front of orbit and behind posterior nostril; nasal bones curved, channeled, the 
raised margins with uniform small teeth directed backward; a low ridge traversing cheeks from 
preorbital to upper portion of preopercle, passing anteriorly to the inner side of a low sharp ridge 
which runs the length of the preorbital; suborbital ridge rising posteriorly, almost uniformly serrate 
with backwardly directed teeth, 18 to 20 in number, a few of the posterior teeth only becoming 
slightly larger; where the suborbital ridge joins the preopercle the margin of the latter is abruptly 
produced to form a sharp triangular prominence which bears a double spine but little larger than the 
last of the suborbital series; below this, the margin of the preopercle bears 3 or 4 small spinous points, 
confined to the region above the angle; opercle with 2 curved diverging ridges, ending each in a spine; 
upper rib curving around a thinner semicircular portion of membrane at upper end of opercular flap; 
seen from above, this has a pore-like appearance, and functions as does the pore in Callionymus; top 
of head with short ridges ending in spines, an occipital pair, one behind each eye, and 2 pairs on 
post-temporals; gill-openings widely cleft, the membranes wholly free from each other; gills 34, the 
laminse very narrow; a wide slit behind last gill-arch; gill-rakers short but strong, the longest about i 
diameter of pupil, decreasing in length anteriorly from angle of arch; 6 on horizontal limb of outer 
arch, the anterior 1 or 2 rudimentary and immovable; branchiostegal rays 7. 
First dorsal short, of sharp moderately strong spines, the third spine longest, 16 hundredths of 
length to base of caudal; base of first dorsal 19; base of second dorsal 30; space between dorsals 2; 
first ray of soft dorsal simple, all the other rays forked for distal third or fourth of their length, 
a By error labeled Bembradium roseus on plate.
