(3) Ramus communicans n. glossopharyngei cum n. maxillari.— 
This nerve includes the ramus recurrens n. maxillaris ad n. facialem of 
Fischer, 52, and Watkinson, 06, which, as described by these authors, 
runs from the ramus maxillaris V over the top of the head to the ramus 
posterior VII. A study of Lacerta and Monitor has shown, however, 
that Fisher’s nerve is really but a part of a longer tract which con- 
nects the glossopharyngeus with the ramus mavyillaris V. This nerve,
