摘要：

Measurements of the percentages of retinal area occupied by visual cell outer segments in cross section were completed for two geckos, Gekko gekko and Eublipharis macularis, and found to be 63 and 57 per cent respectively. From these measurements, the visual pigment density at λmax per individual rod was calculated to be 0.58 and 0.71 respectively, and the corrected densities for the entire central retina 0.48 and 0.52 respectively. These latter values correspond to mean values of 67 and 70 per cent, for the percentage of light absorbed at λmax by the entire retina. Errors associated with these measurements are discussed. © 1969.
