REVISION OF THE FISH FAMILY LIPARIDAE 71 



Distribution. — Japan Sea, only the type known, apparently a deep- 

 water species. 



Relationship. — L. frenatus is not closely related to any known 

 species. It can be distinguished from L. cyclopus, which it resembles 

 in many characters, by the increased number of fin rays, the large 

 gill slit, and the narrow head. 



Synopsis. — Dorsal 37; anal 31; pecto- 

 ral 34; pyloric coeca 21; disk 2.5 in the 

 head. Gill slit extending down in front 

 of nine pectoral raj^s. Dorsal fin un- 

 notched, connected to the caudal fin 

 for less than one-fifth of the length of 

 the latter. 



RemarJcs. — L. frenatus has an unusu- -n ., ■, 



•' . . FlQUEE 7.— LiPARIS FRENATUS. TeETH 



ally narrow head and in this respect from type 



resembles the tj'pical forms of Care- 



proctus. The reddish color also suggests an approach to the condition 

 found in Careprodus.

Figure 8. — Liparis fucensis. Teeth from type 



Type.— Femsile, No. 48600, U.S.N.M., Straits of Juan de Fuca, 

 Albatross Station 3451; depth 106 fathoms. Length 110 mm. 



Distribution. — Coast of Washington and southeastern Alaska, 

 Albatross Stations 2865, 3451, 3452, 3461, 4302, and from Port Ludlow, 

 Wash.; depth, shallow water dovm to 212 fathoms, at present not 

 known to inhabit the tide pools. Thirteen specimens examined. 



Relationship.— L. fucensis apparently is not closely related to any 

 known species. In the character of gill opening and increased 

 number of pectoral rays it represents a transition stage between
