The Sun-fish therefore comes into line with the typical Teleostean con- dition. I have nothing to add to the description of the general relations of the parts of the auditory organ. An attempt to obtain histological details only demonstrated the internal lining of flattened cells be- coming columnar in the recessus and ampullae, and the external fibrous layer containing the blood vessels and transmitting the nerves to the ampullae and the reduced and conjoined utriculus and sacculus. But it was some days after its capture before the specimen came into my hands. Orbit. The eye as has often before been pointed out is large — in the present case it measured 4 cm in diameter. It does not seem to have been previously noticed that the optic nerve does not emerge from the group of recti muscles, but in front of them, and that the nerve is supported by a strong fibro-elastic band proceeding from the closely set origins of these muscles. The ligament is inser- ted into the sheath of the nerve just before the latter passes into the eye (Fig. 3). A so-called nictitating membrane or third eyelid has been.
