Table 2. — Lengths at Different Ages op 65 Examples of Cynoscion regalis as Calculated 

 FROM THE Scales and as Averages of Measured Year Classes, with the Number of Fish 

 Measured in Each Case. 



« As the number i, 2, 3, and 4 year-old 6sh used in table i was small the present table includes 27 additional specimens 

 employed for length measurements, their distribution is indicated by the numbers in parentheses.

Table 4. — Relative Distance Apart of the Annuli (Arbitrary Standard), and the Number 



OF Circuli Between Each Two. 



<■ Different series from table z. The fortuity that the small number of scales more than three years old includes, No. 4, 

 10. and 39 which have an unusually large number of radii, serves in a measure to obscure the purpose of the table; with these 

 abnormal figures omitted throughout, the averages corroborate the fact that it is otherwise obvious to one who examines the 

 scales.
