100 NEW FISHES FROM PACIFIC COAST GILBERT. 



Teeth in a rather broad cardiform baud on front of upper jaw, becom- 

 ing narrow laterally. In lower jaw a single series, or an irregular 

 double series anteriorly. Vomer and palatines toothless. 



Eyes small, very close together, the interorbital width about half their 

 diameter, which equals length of snout, and is about one-eighth head. 

 Gill laminPB much reduced in size; a small round pore behind inner 

 arch. Gill rakers obsolete; pseudobranchiiTe small but evident. Oper- 

 cular fringes composed of eighteen filaments. 



Dorsal beginning at a distance behind occiput equaling diameter of 

 orbit. The anterior rays are but partly joined by membrane, the first 

 ten or eleven slender and not articulated. The last ray is distant from 

 base of caudal about a diameter of orbit. Origin of anal under sixth 

 dorsal spine, the two anterior rays not articulated. Pectorals short, 

 1| in head, containing fourteen or fifteen rays. Caudal very small, with 

 ten developed rays, its length 2f in head. 



D. X or XI, 29 or 30; A. II, 32 or 33; lateral line running high in its 

 anterior portion, declining on three or four scales, the posterior portion 

 on middle of sides with twenty-nine or thirty tubes. Four scales be- 

 tween median portions of lateral line and base of dorsal. 



Color : Light olivaceous, a dark streak along back, one along middle 

 of sides, and a fainter one along base of anal, formed by darker margins 

 to the scales. Median dorsal line with ten or eleven more or less evi- 

 dent narrow pearly white cross bars. Top of head and front of man- 

 dible colored like the back, the pearly blotches varying in size and shape, 

 but symmetrically arranged, many of them narrowly edged with black. 

 Nasal tentacle white. White streaks on preopercle. Caudal with a 

 narrow black bar at base. 



Three specimens, the longest 3 inches, from Stations 2797 and 3012^ 

 the latter in 22 fathoms. 



63. Labrosomus cremnobates sp. nov. 



Differing from other described species of this genus in the much 

 larger scales. Head 3^ in length; depth 4f. D. XXI or XXII, 8; A, 

 II, 19, Lat. 1. 37. L. 3 J inches. 



In appearance resembling very strongly the species of the genus 

 Attchenopterus. Body slender, snout sharp, the jaws equal. Mouth 

 wide, oblique, the maxillary reaching vertical from posterior margin of 

 orbit, 2^ in head. 



Teeth small, villiform, forming a band in front of upper jaw, the outer 

 series enlarged. In lower jaw a single series laterally, becoming double 

 in front. Similar teeth on vomer and palatines. Eye longer than 

 snout, 4 in head. Interorbital width less than diameter of pupils. 

 Opercle terminating in an evenly convex process behind, without spin- 

 ous points. Gill membranes broadly united, free from isthmus. No 

 hook on inner edge of shoulder girdle. Nostrils with a flap. A single 

 slender filament on eye and one or more on each side of the nape.
