A previous light microscopic study of the retina of Telescopus fallax has showed the presence of three types of photoreceptors: large single cones (type A), large double cones (type B), and small single rods (type D). The present electron microscopic study has demonstrated that the small single rod is a morphological cone characterized by possessing a slightly tapering outer segment and a very extensive zone of continuity between the discs and the plasma membrane of the outer segment.
