Summary

A method is described that allows the spectral sensitivity of photoreceptors to be measured with high spectral resolution. It is shown that the sensitivity of the ocelli ofMusca andCalliphora has a vibrational fine structure in the ultraviolet, strongly indicative of a sensitizing pigment. The visual pigment has its absorption maximum close to 425 nm.
