A single lens was found' in the eye but the retina was so macerated that no exact information could be obtained as to the distribution of the optic nerves. Summary. 1. The presence of a definite nasal septum of cartilage and the innervation of the proboscis supports Wilder's view that the frontal proboscis is a normal structure that has been prevented from taking its usual position because of the location of the median eye. 2. The inferior oblique muscles have fused into a single muscle, both ends of which are inserted in the sclera of the e3'e. 3. The optic nerves do not form a chiasma. 4. All of the regions of the brain except the telencephalon are -apparently normal, unless it is the floor of the diencephalon. AH of the 12 pairs of cranial nerves were located except the first, the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Anatomische Gesellschaft.
