In the latter the V . central rings are as a \ rule very large, the ^v subsequent rings be- coming narrower as the fish grows older. If the rings in the scale of Bathygadus signify periods of growth, thesewouldseem to be of a peculiar character, cm. in length from the. Fig. 564. Scale of Canthariis lineatus, Montagu (White). Length of fish, 42 cm. Fig. 564 is the scale of coast banks of Africa, Cantharus lineatus, taken in shallow water at a high temperature. This scale also shows rings which are very distinct, especially to- wards the periphery of the scale. In Fig. 565 I have represented a scale from a surface fish, Polyprioii americanus, 49 cm. in length, taken in the surface waters at Station 56. In the scales of all these fishes, taken under such various conditions, we observe peculiarities of struc- ture, resembling the ⢠1 1 r rings produced by the periodicity of growth m the scales ot fish from boreal waters. There seems thus to be every reason for subjecting the growth of the scales and other organs of.
