426 NEW FISHES FROM PACIFIC OCEAN— GILBERT 4' CRAMER, vol. xix. 



of orbit, about 3 in head. Teeth in villiform bands on both Jaws, the 

 outer series of i)reniaxillary teeth h)nger than the inner, but not canine- 

 like; mandibuhir teeth smaller. Orbit 3^ in head, Its upi)er margin 

 near the profile. Posterior edge of preopercle nearly vertical, slightly 

 serrulate. r>arl)el small, scar(;ely more than one-third diameter of orbit. 

 Gill membranes broadly united with a very narrow free fold behind. 

 Anterior gill slit very short, 2^ to 2| in diameter of orbit. Body 

 compressed, its width about one-half its depth. Scales of moderate 

 size, not very deciduous, with 25 to 50 very long slender backwardly 

 directed spinelets arranged in about 8 to 10 somewhat irregular par- 

 allel series; 9 to 10 scales in a transverse row between origin of 

 first dorsal and lateral line. Interorbit.il space, upper side of snout, 

 infraorbital ring, under sides of lower jaw, cheeks, and opercles com- 

 pletely scaled. Anterior part of lateral line with a strong convex curve 

 reaching middle of sides slightly in advance of origin of second dorsal. 

 Second dorsal spine serrate, prolonged into a filament, its length slightly 

 less than head. Base of first dorsal much greater than interorbital 

 space, nearly equal to orbit. Distance between dorsals equal to twice 

 the base of first dorsal. Pectorals near axis of body, slender, about 

 1| in head. Outer ventral ray prolonged in a slender filament, twice 

 as long as the other rays, which reach origin of anal. Origin of anal 

 nearly under middle of interspace between dorsals. Vent twice as far 

 from origin of anal as from axils of ventrals. Distance from base of 

 ventrals to origin of anal equal to length of snout. A small, round, 

 naked pit between bases of ventrals, its width about one- third diameter 

 of pupil. 



Color {in alcohol). — Light brownish, with minute dark ]KiiH'tulations. 

 Lips, branchiostegal membranes, mouth and gill cavities, and lower 

 half of sides of trunk brownish black. Abdomen bluish l)lack. First 

 dorsal and ventral fins blackish, the ventral filament white; basal por- 

 tion of anterior anal rays, blackish; axil of pectorals black, the fins 

 slightly dusky. Peritoneum silvery, washed and dotted with brownish 

 black. 



Three specimens, C^ to 7^ inches long, fi-om stations 3474 and 3475; 

 375 and 351 fathoms, respectively. 



Type— 1^0. 47734, U.S.X.M. 



MACROURUS GIBBER, new species. 

 (Plate XLIV, lijr. 2.) 



Head 6^; depth about 5.^; B. 7. First dorsal I, 11 or I 12; second 

 dorsal very low; anal rays well developed; pectorals 20; ventrals 12 

 to 13. 



Head compressed, deep, its greatest depth nearly equal to its length; 

 cheeks vertical. Snout short, but little overhanging the mouth, its 

 length a little less than diameter of orbit; its tip is a small, spiny
