108 IS'EW FISHES FROM PACIFIC COAST GILBERT. 



71. Lycodapus fierasfer sp. nov. 



Bodj- compressed, elongate, tapering rather rapidly backwards, the 

 tail not produced to a filament. Head flat above, the cheeks deep, ver- 

 tical, the mouth very oblique, with the lower jaw slightly the longest 

 and nearly entering the upper profile. Skull very thin and papery, 

 translucent. 



Jaws weak; gape of mouth wide, the maxillary reaching vertical 

 from behind front of pupil, 2 to 2i- in head ; eye 4i ; snout 3^. Teeth 

 all small, in a very narrow band in jaws, in a single series on vomer 

 and palatines. Interorbital width two-thirds of eye. 



Snout broad, depressed, spatulate; its tip prominent, turned upwards, 

 the upper profile thus longitudinally concave. An evident median 

 ridge on snout and interorbital space. Gill slits continued forwards 

 below to vertical from middle of eye, the membranes united for a dis- 

 tance equaling diameter of pupil. Gill-rakers short, less than diame- 

 ter of pupil, strongly toothed, about ten on horizontal limb of arch. 

 Head without conspicuous mucous pores or cavities. 



Dorsal beginning well forwards, its distance from occiput slightly 

 less than that from occiput to nostril. The dorsal and anal rays are 

 slender, all articulated, branched only at tips. Caudal not distinct, 

 the rays springing from end of tail not projecting beyond the others. 



Origin of anal immediately behind vent, its distance from snout 

 nearly equaling one-third total length. Ventrals narrow, varying in 

 length, about 2 J in head. Body and fins invested in a rather lax trans 

 parent skin, without trace of scales. 



D. 82 ; A. 70. Head 5^ in length ; depth 10. 



Color : Body translucent, dusted with black specks. Abdomen black- 

 ish. Lips, inside of mouth, lining of gill cavity, and peritoneum jet- 

 black. Iris silvery. 



Several specimens, the longest 5^^ inches, from stations 2980, .3010, 

 3072, in 610 to 1,005 fathoms. 



72. Leptophidium pardale sp. nov. 



Light-olive, a series of eight black bars downwards from back, scarcely 

 reaching lateral line, sometimes continuous with their fellows of the 

 other side, and alternating with smaller black spots on dorsal outline; 

 below the smaller spots a series of round spots nearly as large as eye 

 along middle line of sides. Sides and lower parts of head and body 

 dusted with rather coarse black specks. Dorsal light, the margin with 

 ten elongate black blotches, usually longer than the intersi)aces. Caudal 

 dusky at base, its distal half white. Anal wholly black. Peritoneum 

 ■and lining of gill cavity white. 



Head 5i in length; depth 8^; L. 7^ inches. 



Body very slender, with a short head and small mouth; maxillary 

 scarcely reaching vertical from posterior border of orbit, its length 2^ 

 in head. Outer teeth very little enlarged, noc movable; teeth present
