| Abstract |
|
1. Fresh and fixed eyes of the diurnal gecko, Phelsuma madagascariensis longinsulae, were examined. 2. This species was found to have a spectacle and no eyelids, a round pupil and a yellow lens. 3. The retina showed the usual three types of gecko visual cell with slender outer segments and colourless oil droplets in one member of Underwood's class B double. It also had a shallow temporal fovea. The general neural structure of the retina was consistent with a diurnal habit. 4. The ocular characteristics of Phelsuma madagascariensis longinsulae are considered to confirm Walls' transmutation theory and to prove that this species has become tertiarily diurnal. © 1961 Springer-Verlag
