Relationships. — P. simushirae is closely allied to P. greeni and P. 

 heringianus. An account of the differences between these three 

 species is given in the discussion of P. greeni. 



Synopsis. — Dorsal 44; anal 34; pectoral 40; pyloric coeca about 300. 

 Disk 2.7 in the head. Dentition resembling that in P. greeni and P. 



Figure 23.— Polypera simushirae. Teeth from type 



heringianus. Dorsal fin notched, connected slightly with the caudal. 

 Color olive brown. Reaching a length of 138 mm.

 and deepened in sharp contrast to the condition typical of the species 

 of Liparis. 



Head. — The head of the species of this genus is typically compressed, 

 the depth being greater than the width. We should note that the
