edly only in pectoral count. In those species 

 where means of characteristics differ noticeably 

 but ranges overlap broadly, S. variegatiis usu- 

 ally is of central value, which suggests that it 

 may be a more generalized member of the group. 



Comparisons of morphometric characters be- 

 tween S. rariegatus and the other species lead 

 to a similar conclusion. Ranges for the species 

 overlap broadly, based on Phillips (1957) and 

 my own measurements (head length, longest 

 dorsal fin spine, least depth of caudal peduncle, 

 pelvic insertion to vent, raker at bend of gill 

 arch, width of pectoral fin base, body depth at 

 pelvic girdle, bony interorbital, orbit, length of 

 pectoral fin, length of pelvic fin, and length of 

 upper jaw — in percent of standard length). 



To assist difl'erentiating S. raiiegatus from 

 similar species a table of discriminatory charac- 

 ters is presented (Table 6). 



GEOGRAPHIC AND BATHYMETRIC RANGE 



Present known range of S. variegatns is from 

 Unimak Pass, Aleutian Islands, to Goose Island 

 Bank, Queen Charlotte Sound' (Figure 5). 

 Depth of capture ranges from 70 to 305 m.
