blind side wavy; snout slightly curved, its upper margin indented 

 at posterior end of premaxillary spine, its length from upper orbit 

 0.05, its outline not quite perpendicular to upper margin of pre- 

 maxillary; maxillary not reaching vertical of anterior margin of 

 pupil by about two-thirds diameter of pupil; jaws of each side 

 nearly straight, the mouth being nearly symmetrical; maxillaries 

 not so wide posteriorly as in L. aspera, their greatest width 0.02; 

 length of maxillary of eyed side 0.075, of blind side 0.08; teeth 

 conical on both sides of jaws, a few along sides of both jaws some- 

 what enlarged, making the series more irregular than in L. aspera; 

 gill-rakers longer than in L. aspera, more constant in size, the ante- 

 rior 4 or 5 on the lower limb not being greatly reduced, the number 

 5 + 10; length of longest gill-raker 0.016. 



Body oval, rather angular at both extremes, its greatest width 0.18 

 of its depth; depth of caudal peduncle, 0.11 ; tip of mandible to anus, 

 0.33; anus partly on blind side. 



Scales on eyed side provided with a single row of sharp but rather 

 weak spines, to 10 in number. Lateral line with an arch, about 7 

 rows of scales between its highest point and the horizontal part; 

 height of arch 12 in straight part, length 3.8; the suborbital branch of 

 lateral line less semicircular than in L. aspera, with 13 pores, clearing 

 the margin of the lower orbit below pupil by 0.01 ; pores in lateral 

 line, both on head and body, in much more pronounced tubes than 

 in L. aspera; interorbital with 3 rows of spinous scales, widening 

 posteriorly to 4 rows; snout, except for anterior margin of orbits, 

 lips on both sides, and on the blind side the exposed portion of the 

 opercular bones and the ridge anterior to nape, naked; fins of eyed 

 side with a few small scales on rays. 



Fins as in L. aspera, except that the ventral is shorter, extending 

 only to anal spine. Height of dorsal, 0.145; of anal, 0.13; length of 

 caudal, 0.21; of pectoral, eyed side, 0.14; blind side, 0.10; ventrals 

 almost perfectly symmetrical, each 0.09. 



Color uniform brown, without spots on fins or body. 



Paratype. — No. 22530, Stanford University Museum. A male 128 

 mm. long, from Albatross station 5025, in 52 fathoms off the east 

 coast of Sakhalin Island. 



Length of head, 0.24 of total length without caudal; depth, 0.39; 

 dorsal, 69 ; anal, 54 ; pores in the lateral line, 83 ; greatest width of 

 head, 0.07; diameter of upper eye, 0.06; entire width of interorbital, 

 0.015; posterior nostril of the blind side with indented edges; length 

 of snout from upper orbit, 0.04; maxillary of eyed side, 0.07, its 

 greatest width, 0.02; gill-rakers 5 + 9, length of longest, 0.016; 

 greatest width of body 0.20 of its depth; tip of mandible to anus, 

 0.30; length of arch in lateral line 3.5 in straight part, its height 14 

 in straight part; interorbital with a single series of ctenoid scales,
