106 NEW FISHES FROM PACIFIC COAST GILBERT. 



tinct, running obliquely downwards to near base of anal, thence back- 

 wards, not reaching' base of caudal fin. 



Color: Dark-brown, black on opercles, sides of snout, fins, and lower 

 parts generally. A broad light bar across head behind eyes, extend- 

 ing down on cheeks; some light mottling on mandible and gular mem- 

 brane. Lower rays of pectorals margined with whitish. Lining of 

 mouth, gill cavity, and peritoneum jet-black. 



A single specimen, 13 inches long, from Station 2980, in 603 fathoms. 



69. Lycodopsis crassilabris sp. nov. 



Body exceedingly slender, the depth 16 in length; head 6f. Occiput 

 flat, forming a right angle with the descending cheeks, the snout short 

 and wide, the upper lip conspicuously thickened and fleshy on the 

 sides. J\[asillary reaching vertical from front of pupil, 3 in head; ex- 

 posed portion of eye 6; snout 4; width of snout 3. 



Upper jaw with a single series of rather large distant teeth ; mandi- 

 ble with a broad patch of cardiforiu teeth anteriorly, which becomes 

 abruptly constricted on middle of lateral portion of jaw, the inner series 

 alone continued backwards towards angle. Palate smooth. 



Head not conspicuously excavated with mucous canals; series of 

 pores present on mandible and sides of head. Gill openings continued 

 forwards to below pectorals, and about to vertical from middle of oper- 

 cle; the width of the isthmus one-fourth the length of slit. Opercular 

 flap with a wide membranous border, produced backwards and largely 

 covering base of pectorals. Gill rakers very little dev-eloped, about 

 twelve movable rudiments on horizontal limb of arch. 



Origin of dorsal in front of middle of pectorals, slightly farther from 

 occiput than is the latter from front of eye. Distance from origin of 

 anal to tip of snout 3^ in total length. Ventrals nearly as long as eye, 

 inserted under middle of opercle. Pectorals with fourteen or fifteen 

 rays, the upper portion of fin longest, the lower rays rapidly shortened, 

 the longest rays half as long as head. 



Scales small, circular, covering nape, breast, and under side of pec- 

 torals, but absent on head. Lateral line single, inconspicuous, running 

 below middle of sides, the pores not developed on the scales. 



Color: Light-brownish above, dark below; lower side of head, mar- 

 gins of snout, gill membranes, part of opercles, and margins of vertical 

 fins jet black. Ventrals and posterior face of pectorals black ; anterior 

 face of pectorals light glaucous-blue, margined with black. Lining of 

 mouth and gill cavity and peritoneum black. 



A single specimen, 12 inches long, from Station 2839. 



Aprodon gen. nov. 



Dift'ering from Lyco 'es only in dentition, the teeth being present in 

 a single strong series on the palatines, but none on the vomer. The 

 genus is thus intermediate between Lycodes and Lycodopsis. 



Type, Aprodon corteziana sp. nov.
