Lightentering the eye from any point between c-d illuminates only certain rhabdomesof the unshaded regions. Light from any point between b-c may illuminate rhab-domes of both the shaded and unshaded regions. when light enters the right eye from a point directly in front ofthe eye, or slightly to the left of this point, the only rhabdomeswhich are illuminated are those lying along the outer, posterioredge (fig. 12, A, a-b). The remaining rhabdomes are shadedby the anterior edge of the pigment-cup. In the same manner,when light enters t
