Fig. 5. Typical absorbance spectra of oil droplets from the cones of Anolis
cristatellus (A) and A. valencienni (B). The absorbances of the
ellipsoid region of the accessory member of the double cones are also shown.
All absorbances that saturated the microspectrophotometer output (optical
density >2.5) were normalized to 1.0, while absorbances below saturation
are shown relative to the normalized absorbances. Thus, the ellipsoid
absorbance in A indicates a very pale ellipsoid and the absorbance of the C1
droplet in B indicates a pale droplet. Although the G and Y droplets always
show very steep cut-offs, as seen here, the ellipsoid and C1 absorbances can
be quite variable. The absorbance of the C2 droplet associated with the
ultraviolet single cone is the dashed line in A and falls on the zero line in
B.
