Nerve fiber counts and the spectral distribution of the myelinated nerve fiber diameters were determined for the vestibular nerve of the White King pigeon. An analysis of variance indicated that the raw data for the utricular, saccular, neglectar, anterior ampullary, and horizontal ampullary nerve branches could be pooled to give am overall unimodal distribution having a mode in the range of 1-2 micrometers. This could not be done for the posterior ampullary nerve and an intraspecific variation was considered to be the cause of the discrepancy. The utricular nerve had more fibers smaller than 3 micrometers in diameter 84.9 than the other branches. Overall, 63.8 of fibers exclusive of posterior ampullary nerve were less than 3 micrometers in diameter. Modified author abstract
