48- Paralichthys albiguttus, 12 cm long, fully adapted to a very light gray background. This specimen continuously appeared somewhat darker than the background. Note that the three ocelli have almost entirely disappeared. 49- Individual (B)..., on black and white background (dots 0.5 mm. in diameter).... Dots of this size, no matter how numerous, had no effect except perhaps to cause the skin to become uniformly slightly grayer. 50- Individual (B) on black and white background (dots 1 mm in diameter)...after having been fully adapted to 1 cm. squares. These spots have no appreciable effect on the skin unless they are more numerous than they are in this background. 51- Individual (B) on black and white background (dots 1 mm. in diameter)....after having been fully adapted to dots 2 mm. in diameter. Note that the posterior ocellus is much darker than on white, but that the two anterior ones are not....
