1. Spectral absorption is measured in a single cone from the carp retina, by a specially designed microspectrophotometer.
2. Five photopigments having λmax 490-500mμ, 520-540mμ, 560-580mμ, 620-640mμ and670-680mμ are detected in various cone outer segments. The occurrence frequency is high for the first three.
3. As to the rod pigment, the λmax, is between520-530mμ in the carp and between500-505mμ in the frog.
4. A few cones which seem to possess two photopigments are observed in the carp.
