It does not appear to me altogether probable, judging from the facts 
given above, and those that follow from the older groups, that all the 
turbot up to 13cm. (53 inches) are under one year of age. It will be 
observed that the young turbot are rather smaller than the young brill, 
and it must be borne in mind that the addition of a unit of length toa 
turbot means a much greater increase in growth than to any other 
fiat fish, owing to its breadth and thickness and its consequent greater 
proportional weight.* 
If regarded provisionally as approaching their second year, then the 
next group, from 13cm. to 17em. or 18cm. (5% to 7 inches), must be looked 
upon as nearing their third year; the fourth group, from 17cm. or 18cm. 
to 22cm. (7 to 8? inches), as nearing their fourth year; and those from 
22cm. to 26cm. (8? to 107 inches) as approaching their fifth year.

The possibility of each of these groups being a year younger must not 
be lost sight of ; in any event, those of the latter size can scarcely be less 
than four years of age or near it. 
Turning now to the collections which contain the larger fishes, we have 
some in October, November, December, and February, which are of 
interest. The measurements are given in Table XVII. 
Although the numbers are not large in any instance, the arrangement 
and order of the figures are such as te lead to the supposition that the 
groups are of small dimensions. 
The group above referred to, from the stake-nets, as extending from 
about 22cm. to 26cm., is represented by only a single specimen, at 23cm., 
taken in December at Burghead Bay. It is at the end of either its fourth 
or fifth summer.
