 Liparis ochotensis Schmidt, Pisces Marium Orientaliuni, 190-1, p. 103 (Okhotsk Sea). 



Tlio following description will servo for comparison with other 

 allied species of our collection: 



Head 3.3 in length; depth 2.8. Dorsal 45; anal 30; pectoral 42. 

 Eye 8.8 in head; snout 2.6; gill sht 2.2; disk 2.5; pyloric cseca 23. 



Body heavy and deep anteriorly, ta])ering rapidly to the caudal, 

 the greatest depth at shoulders. Head short and deep, the occiput 

 slightly swollen, the profde steep; interorbital space broad; the 

 distance between the anterior nostrils contained 3.6 times in the 

 head. Snout short and broad, rising abruptly; jaws equal. Anterior 

 nostrils in a prominent tube; posterior nostril -with a raised rim. 

 Eye small, round. Mouth broad; maxillary reaching vertical from 

 just behind the eye. Teeth slender, weakly trilobed, in a broad 

 band, arranged in about 25 oblique rows in the half of each jaw, those 

 of the anterior series minute. Gill slit broad, extending down in 

 front of 18 pectoral rays. 



Anterior dorsal rays buried in a gelatinous tissue; distance from 

 tip of snout to dorsal 2.8 in body. Caudal broad, slightly rounded. 

 Dorsal and anal joined to basal half of caudal, the anal a little more 

 widely joined than the dorsal; last rays of both dorsal and anal 

 shortened, forming rounded lobes, pectoral broad, notched; the 

 lower lobe thickened, vntli partly free ra3's reaching two-thirds the 

 distance from disk to vent. Disk nearly round; distance from tip 

 of lower jaw to disk 8.4 in length; from disk to origin of anal 4.8. 

 Vent separated from disk by a little less than diameter of disk. 



Coloration: Top of head and sides and back of body with bluish 

 black stripes, these darker along the edges and sometimes dividing 

 posteriorly to form two stripes; lower parts of body pale; margin of 

 pectoral, doi-sal, and anal bluish black; caudal blackish; lower lobe 

 of pectoral not so dark as the upper. 



Thumb-tack prickles on top of head and on back; those on sides 

 smaller; lower surfaces smooth. 



This species differs from C. agassizii in the increased number of 

 pectoral rays. The description is from a female sj^ecimen 465 mm. 

 long, from station 5008, in Aniva Bay, Sagalin Island, at a depth of 

 40 fathoms. Young specimens were taken in the same locality at 

 stations 5010 and 5012, depths 21 and 42 fathoms; and others from 

 stations 5016, 5017, 5020, 5021, and 5023, off the eastern coast of 

 Sagalin, at depths of 64 to 75 fathoms. 



As in certain other species of the genus, C. ochotensis displays 

 distinct color patterns. Certain of our specimens are conspicuously 

 marked with longitudinal black streaks, others with light blotches 

 of var3'ing size and shape, narrowly margined with dusky, while the 

 majority are gray, finely spotted or variegated with darker.
