Summary The spectral sensitivities of the four eyes ofNereis mediator (Polychaeta, Annelida) were measured from 400 nm to 600 nm by determining the reciprocal of the number of quanta required to elicit a constant electroretinogram of 350 μV.N. mediator is maximally sensitive at 480 nm, although it is very sensitive over a broad range from 400 nm to 540 nm (Fig. 4). Selective adaptation experiments (Fig. 5) and changes in the time characteristics of the electroretinogram under conditions of dark and green adaptation (Fig. 2) indicate the presence of a multi-receptor system.
