dc.descriptionIn this paper we analyze the topographic distribution and cell body size of neurons (ganglion and displaced amacrine) of layer 8 of the retina in the chilean reptile Callopistes palluma; using whole mount retinaswith nissl stain. Callopistes palluma retina has an area centralis without fovea in which the ganglion cell density amounts 20.000 cells / µm2 while the displaced amacrine neurons is about 7.000 cells / µm2. This neural density decreased gradually towards the peripheral retina. A horizontal streak is also present for both types of neurons. In the different areas of the retina the displaced amacrine neurons correspond to 25%-30% of the total number of neurons in layer 8. The analysis of the neuronal size shows that in the area centralis the ganglion cells have a mean body size of 32 µm2 while the displaced amacrine neurons have a mean body size of 8 µm2. In the peripheral retina the cell body size increase to 42 µm2 for the ganglion cells and to 12 µm2 for the displaced amacrine neurons. In the paper is discussed the correlation betweem retinal characteristics and styles of prey hunting
