Anterior to this a second branch of the pro- fundus V leaves the nasal cavity through the canal opening into the anterior palatal recess (Fig. 3, ). I have termed this branch the "ramus rostralis" of the ramus medialis narium (Fig. 6, ). The canal carrying this nerve has a slight connection with that carrying the ophthalmicus superficialis VII nerve, but anastomosis between these two nerves in this position seems un- likely and the connecting canal probably contained a small vessel. A third set of branches of the ramus medialis narium, which I have termed the "anterior rami" (Fig. 6, ), pass through the anterior nasal Figure 7. Ectosieorhachis.
