FISHES OF HAWAIIAN ISLANDS. (537 



The species of Txmanotux have been very insufficiently described and figured. It is by no means 

 evident tliat all tlie specimens listed as T:i:iiiniiotns triacantJius Lacepede are conspecific. tiiinthei-'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. cilrindhis with any of 

 these, or with T. ii<m-etti Giinther, 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 Stcinilachner. 



One yciuMg specimen from station .■W4it, off the south coast of Jlolokai, depth 4.') to 7.'! fathoms. 



Family BEMBRID.^i. 



Bembradium, new genus. 



Related to ParahemhmK, from which it differs in having much larger scales, a lateral line running 

 near middle of Ixidy (as in Ikmhras), not parallel with the back, and a short mandilile included within 

 tlie upjier jaw. 



Ill iiihiiuUuin tiilbert, now genus of Bnnhrida' (rotnum). 



Bembradium roseum, new species. Plate 82." 



Type, 90 mm. long, from station 3S.jl», I'ailolo Channel, depth l.'iS fathoms; type. No. .51(517, 

 U. S. Nat. JIus. 



Head 40 hundredths of total length without caudal; depth IS; width of snout 14; length of snout 

 13 (to front of eyeball); eye 11; interorbital width 2; maxillary IS. D. ix-12; A. 11; V. i, .5; I'. 25. 

 Lateral line 2S; oi horizontal series of scales aliove lateral line. 



Body elongate, gently compressed along dorsal regifin; 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 nuddle of length of snout, and iliverging 

 posteriorly more rapidly, not eontimiing 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 jireopercle the margin of the latter is abruptly 

 produced to form a sharp triangular prominence which liears a doulile spini' 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 aliove the angle; opercle with 2 curved diverging ridges, ending each in a S])ini'; 

 upper rib curving around a thinner semicircular ])ortion of memlirane at upper end of opercular flaj); 

 seen from aliove, this has a pore-like appearance, and functions as does the pore in Callioniiitius; 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 3i, the 

 laminic very narrow; a wide slit behind last gill-arch; gill-rakers short but strong, the longest about ^ 

 diameter of pupil, decreasing iu 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 abort, of sharp moderately strong spines, the third .spine longest, 1(> 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 ncmliradiunt roacus on plate.
