anteriorly and other posteriorly in distribution to the dorsal and 
lateral walls of the pharynx. Between some of them and similar 
branches of the ramus posttrematicus there may occur anastomo- 
ses. One of these small branches of the ramus pretrematicus (or 
one given off more posteriorly, or two anastomosing branches) 
connects with the so-called posterior palatine branch of the alveo- 
lar-palatine trunk of the facial nerve, thus forming a Jacobson’s

anastomosis (jc.). The middle portion of the anastomosis is 
very much attenuated, but it is larger at the ends, showing that 
it is made up largely of pharyngeal fibers of the ninth and seventh 
nerves, and only a small part of it extends from one nerve to the 
other. In some instances it is double in character almost its 
entire length. 
Anastomoses of communis fibers between the ninth and seventh 
nerves seem to be common if not universal in the Urodela. In
