ern type south of Dixon Entrance and the north- 

 ern type North of Dixon Entrance and in the Gulf 

 of Alaska, Differences in gene frequencies would 

 add to the support of their separations. This 

 approach may also prove useful in studying com- 

 plexes such as found in S. aleutianus, S. reedi, 

 and S. diploproa (Tsuyuki et al., 1968). 



SUMMARY 



An investigation of muscle protein and six en- 

 zymatic systems by starch-gel electrophoresis 

 was presented. Samples of 31 species of three 

 genera of the family Scorpaenidae were com- 

 pared which resulted in the conclusion that a 

 relatively greater similarity existed between the 

 Pacific Sebastes and the Atlantic Sebastes than 

 between the other genera. 



Ten of the 27 species of Pacific Sebastes had 

 unique profiles when the systems were compared.
