paratively short distance anterior to the anastomosis. The re- 
maining general cutaneous fibers, profundus and maxillaris, unite 
with the medial palatine (pal.1) in two or three anastomoses. As 
the medial palatine has already divided it is only with the lateral 
of its two divisions that these unions take place. The exact 
composition of the general cutaneous constituents of the profundus- 
palatine anastomosis usually cannot be determined with accuracy, 
but in one instance where the lateral profundus constituent 
arose from the ramulus nasalis externus it was possible to see that 
the maxillaris element from the infra-orbital trunk passed into 
both the lateral and the medial resulting nerves. This excep- 
tional origin of the lateral profundus constituent from the ramu- 
lus nasalis externus is reported by Coghill (’06, p. 254) in Triton. 
An anastomosing of branches of the ramus buccalis VII and 
the ramus ophthalmicus profundus V is not uncommon, it would 
seem, in the Urodela. In Amphiuma, as shown by Wilder and 
the writer, the buccalis anastomoses with two branches of the 
ramus ophthalmicus profundus, (op.(4) and op.(5)) which may 
be considered as collectively representing the ramulus nasalis 
externus V. In Cryptobranchus (Menopoma) alleghaniensis 
Wilder describes similar anastomoses which are evidently be- 
tween the buccalis and branches of the ophthalmicus profundus, 
similar to those in Amphiuma. In C. japonicus (Osawa ’02) 
the anastomoses appear to be almost identical with those in C. 
alleghaniensis. It is possible that this particular kind of anasto- 
mosing may be peculiar to the derotreme Urodela, for in Siren 
and in Triton the relations are somewhat different. A study 
should be made of both species of Cryptobranchus from the 
standpoint of nerve components. 
5. Trigeminal fibers entering the facial nerve 
Groups of fibers (V ad VII), after becoming ganglionated 
in the Gasserian ganglion, may be traced dorsally into the great 
lateral line trunks which pass anteriorly out of the dorsal lateral 
line ganglion (fig. 12). Their subsequent course will be noticed 
in the description of the rami of the facial nerve.
