The vast majority of ‘oil-droplets’ in the dark and light-adapted retinal twin-cones ofPoecilia reticulata is of the ‘matrix-type’. In bright light (day light+overhead strip light) there occurs in some regions a very pronounced numerical change from ‘matrix’ to ‘cristate-type’, whereas other regions remain unaffected. The functional significance of these differences is discussed.
