Inner molecular layer: d, inner nuclei; e, outer molecular layer; /, coue-flbres with their outer nuclei; g, cones. externa. For this reason, the rest of the outer nuclear layer is occupied by the cone-Hbres only, which in the fovea centralis pass in a slanting, or almost horizontal, direction sideways into the outer molecular layer. The ganglion cells fi)rm several strata in the macula lutea. In the fovea centralis are present the cones (very long and thin), the limitans externa, the few nuclei repre- senting the outer nuclear laj^er, a thin continuation of the inner molecular layer, and the limitans interna. 448.
