THE NATURE OF THE LAMPREY VISUAL PIGMENT [PDF]
The Journal of General Physiology, 1956 From the retina of the land-locked population of the sea lamprey, Petromyzon marinus, a photolabile pigment was extracted which was identified spectrophotometrically as a member of the rhodopsin group of pigments. Using the absorption spectrum of a relatively pure solution and analysis by means of difference spectra, the peak of this pigment was placed

THE NATURE OF THE GECKO VISUAL PIGMENT [PDF]
The Journal of General Physiology, 1956 Retinal extracts of the Australian gecko, Phyllurus milii (White), have revealed the presence of a photosensitive pigment, unusual for terrestrial animals, because of its absorption maximum at 524 mµ. This pigment has an absorption spectrum which is identical in form with that of other visual chromoproteins.

Nature of the Pigment of Aplysia depilans [PDF]
Nature, 1955 BY heating an aqueous solution of the actual excretion of the Mediterranean sea-slug Aplysia depilans, the violet pigment is separated from its protein part. The colour of the aqueous solution varies conformably with the pH, from blue (pH 1—2) to garnet red (pH 8—12.0).
