The anatomical and clinical evidence for the presence of gen- 

 eral cutaneous fibers in the nervus facialis is meager in amount 

 and inconclusive. In petromyzonts, Johnston ('08) describes gen- 

 eral cutaneous fibers arising from the geniculate ganglion and 

 passing to the ventrolateral surface of the head below and behind

the orbit. In bony fish, Herrick ('99, '00, '01) found a general 

 cutaneous component in the facial nerve for the region of the 

 operculum, the fibers, however, being derived from the Gasserian 

 ganglion. In the amphibia, Norris ('13) found a general cutane- 

 ous component in Siren, and Herrick ('14) described fibers from 

 the geniculate ganglion in Amblystoma larva which enter the
