The work of this paper is based upon the photographic and descriptive material presented by Dr. A. A. Gray in his two volumes on 'The Labyrinth of Animals,’ published by J. and A. Churchill, London, in 1907 and 1908. I have succeeded in extracting from that impressive mass of material definite results that seem to be of some importance. The dimensions of the cochlea measured by Dr. Gray are: (1) the diameter of the lowest whorl and (2) of the second whorl (“taken in a plane which passes vertically through the apex of the cochlea and the anterior margin of the round window”); (3) the diameter of the tube of the cochlea in front of the round window; (4) the major axis of the oval window: (5) the slant height of the cochlea (“the distance from the upper margin of the round window to the apex of the organ”); and (6) the number of turns of the cochlea.
