secondary and unimportant connection with the vagus, 
and the N. vagus sensw stricto. There are no intracranial 
branches from the vagus Complex, as stated by 
Stannius. 
R. lateralis vagi (r. /at. v.).—Arises from the tuber- 
culum acusticum, like the auditory nerve and other lateral 
line nerves, but appreciably below the exit of the latter 
and considerably above and somewhat in front of the root 
of the glossopharyngeus. It also arises considerably in 
front of the roots of the true vagus. The root (r. lat. 2.*) 
passes downwards and backwards, lying immediately 
external to that of the vagus proper, and for a time 
between it and the posterior division of the acusticus, as 
above described. It has, however, no connection with 
either, and passes out of the same foramen (indicated by 
a ving in the chart) as the rest of the vagus, but external 
to the latter. As in Mentdia the lateralis consists mostly 
of the large strongly myelinated nerve fibres, but also has 
many smaller ones. 
immediately on leaving the skull the lateralis gives 
off the R. supratemporalis vagi (1. st. #.), at the base of 
which is a small ganglion distinct from the main lateralis 
ganglion. The supratemporal branch, as shown in the 
chart, is distributed on the ocular side to the 4 sense 
organs so far developed in the supratemporal portion of 
the lateral canal, and also to the first two sense organs in 
the main portion of the same, 2.e., sense organs 1 to 6. 
After giving off this branch the lateralis expands into the 
lateralis ganglion (/. g. w.). The nerve arising from the 
ganglion passes upwards, and divides, as in the Cod, into. 
the R. lateralis superficialis vagi (7. lat. swp. #.), coursing 
just under the skin in the neighbourhood of the main 
portion of the lateral canal the sense organs of the anterior 
half of which it supplies, and the R. lateralis profundus
