Liparis ochotensis Schmidt, 1904o, p. 163. 



Cydogaster ochotensis Gilbert and Burke, 19126, p. 359. 



T?/^es.— Male, No. 12963 and 12964, Museum of the Imperial 

 Academy of Sciences, St. Petersburg. Saghalin Island. 



Distribution. — Shallow waters about Saghalin Island, Okhotsk 

 Sea, our specimens from Cape Terpenis and Anuva Bay, Saghalin; 

 depth 21-43 fathoms. Six specimens examined. 



Relationships. — L. ochotensis appears to be most closely related to 

 L. ingens. It differs from the latter species in the characters of the 

 teeth, equal jaws, and stouter body. It is readily distinguished from 

 L. agassizii by the larger gill slit and smaller number of pyloric coeca. 

 See descriptions of L. gibhus, and L. rhodosoma for comparisons with 

 these species. 



Description of type. — No. 12963, male, length 195 mm. Dorsal 

 45, anal 36; pectoral 39; pyloric coeca 25. Depth 3.5 in length 

 without caudal; head 3.3. Disk 2.6 in head. 



Body rather deep, dorsal outline sloping gradually. Head broad, 



depth greater than mdth; 

 profile gradual, slightly 

 depressed over the eyes; 

 occiput not swollen. 

 Mouth broad; maxillary 

 reaching pupil. Teeth 

 trilobed, recurved; the 

 lateral lobes not so prom- 

 inent on the larger teeth; 

 in broad bands, arranged 

 in about 17 oblique rows in the half of each jaw. Snout short, de- 

 pressed; jaws nearly equal. Anterior nostril in a tube; posterior 

 nostril with a prominent rim. Eye small, 6.1 in head. Gill slit ex- 

 tending down in front of 18 pectoral rays, equal to snout. A few 

 minute prickles on head, these consisting of a small round base and 

 a short thick conical spine. 



Dorsal fm high, the rays increasing in length to middle of fin or 

 beyond, at this point 1.5 times the length of the snout. Anal resem- 

 bling dorsal, the rays not quite so long. Caudal slightly rounded, 

 connected for nearly one-half its length to the dorsal. Pectoral 

 broad; the lower lobe of six rays, reacliing three-fourths the distance 

 from disk to vent. Disk large, with a broad flap. Vent separated 

 from disk by nearly diameter of disk. 



Color grayish; narrow, paired, dusky stripes on head, body, and 

 base of dorsal; these sometimes united anteriorly to form single 

 stripes; margin of dorsal and anal mottled and dusky; caudal mottled 

 and barred with dusky marldngs; margin of pectoral dusky; peri- 

 toneum pale, with scattered dots.
