SALMON AND TROUT IN ALASKA. 

 Table 7. — Anal Fin-Ray Count. 



The branchiostegal rays exhibit Kttle local variation in number. 

 The maximum in practically all cases falls on 14/13, the left over- 

 lapping membrane carrying the extra ray; about one-third the total 

 occurs on this maximum. Extremes are 12/11 and 16/15. Quadra 

 and Kegan resemble one another in rising high on 13/13 and failing 

 low on 14/14 and the higher counts. Karta and Dolomi exhibit the 

 highest counts on 14/14. In no instance was a clearly defined case 

 of right overlapping seen, though occasionall}^ the right membrane 

 carries the higher number of rays.
