The inner ear of the caecilian Ichthyophis glutinosus is briefly described. An analysis of the fine structure of the utricular macula show the presence of several varieties of hair cells. At least one type seems to be degenerating, another developing. A slow hair cell turnover is proposed. The number of afferent nerve endings in contact with a few hair cells were found to be 6–13 as reconstructed from electron microscopical serial sectioning.
