Reviewing the eight years for which we have here presented records variously 

 complete or incomplete, we find that the Karluk race is most diversified in its lines 

 of development, apparently more so than is the case with any other race we have 

 examined. Seventeen distinct age groups have been represented in one or more of 

 these runs, all but three of them being detected in the run of 1926. The complete 

 list is as follows, the principal figure representing the year of its age in which the 

 fish matured and the smaller figure the year of its age in which it migrated seawards : 

 3i, 3 2 , 3 3 , fi, 4 2 , 4 3 , 4 4 , 5 2 , 5 3 , 5 4 , 5 5 , 6 3 , 6 4 , 6 5 , 7 4 , 7 5 , 8 4 . 



For comparison with previous years, we present Table 19, giving the age-group 

 composition of the run, as evidenced by our daily samplings. The dominant group, 

 5 3 , does not vary widely during the season but is relatively most numerous in the 

 spring and late summer, with an intervening period in July when it is obviously 

 less abundantly represented. The next two groups, in order of importance, are 6 3 

 and 6 4 , which follow their usual procedure, the former increasing in abundance as 

 the season progresses, while the 6 3 group is in relatively greater number early in the 

 spring and almost wholly disappears before fall. 



The minor groups, in general, make their entrances and exits and are present 

 most abundantly during the periods already indicated for previous runs. The 3 s 

 and 4i groups vary in 1926 from what we have previously observed, inasmuch as they
