Henle says that this is the most con-stant of the muscles of the auricle, and that it is often thestrongest of the intrinsic muscles. It is a fan-shaped muscle,and is found on the lateral surface of the helix between itsroot and spine. (Fig. 3, 3.) 4. Helicis Major.—This muscle runs over the anterior mar-gin of the helix, and is only loosely connected with it, andpasses over by a kind of tendinous termination into the levatorof the auricle.
