The peripheral facial nerve and facial muscles were investigated Tupaia glis from the phylogenic point of view by a special dissection technique through the bone surface.The facial nerve of Tupaia glis spread out in a six branch like fan without diverging to the superior and inferior as in man.The peripheral branches of the facial nerve could be easily distinguished one by one, because the divergence of the principle branches was simple and orderly.The auther found some thin muscles which passed deeply into the m. maxillo-naso-labialis and named it Pars transversus m. nasalis. However, Clark and Lightoller have reported that only the m. naso-labialis was found there.The m. depressor palpebrae inferioris indicated by Huber in Lemur variegatus also existed in Tupaia glis.
