complex, runs craniad between the V—VII complex and the electric 
nerve where it exhibits a small ganglionic enlargement (Ganglion, Fig. 13). 
From this ganglion two small ciliary branches run forward in the 
electric organ. The ventral one of these (Ciliary N. Fig. 12 and 13) 
accompanies the branch of the third nerve which supplies the rectus 
inferior and enters the eye with the ophthalmic artery. The dorsal 
branch (Fig. 13) runs craniad and mingles so intimately with the 
electric and third nerves that it was impossible with the material at 
hand to trace it further. A small strand, however, which accompanies 
one of the more dorsally situated branches of the electric nerve and 
enters the eyeball just ventral to the insertion of thg rectus superior, 
may be the continuation of this nerve. This ganglionic enlargement 
is also connected with two very fine nerve strands which probably 
belong to the sympathetic system. 
The ramus palatinus runs directly through the ventral portion of 
the electric organ immediately ventral to the carotid artery. Ventral 
to the eyeball, this nerve makes a curve mesad on to the cranial 
surface of the electric organ and then runs craniad, dorsal to the’ 
anterior division of the M. adductor arcus palatini, to its termination in 
the roof of the mouth. 
-The Blood Vessels!). 
The ophthalmic artery leaves the pseudobranch, runs craniodorsad 
along the ventral portion of the lateral surface of the electric organ, 
and enters the eye with one of the ciliary nerves, directly lateral to 
the entrance of the optic nerve. This artery, caudoventral to the 
eyeball, curves mesad around the external carotid artery and the nerve 
to the obliquus inferior, and at this point sends a small branch through 
the electric tissue to the median line where it anastomoses with the 
corresponding artery of the opposite side (Fig. 13). 
The external carotid artery runs craniad through the electric organ 
dorsal to and accompanied by the ramus palatinus. The arterial 
branches to the recti eye muscles could not all be made out; it was 
evident however, that several were given off to the electric tissue. 
The largest of these electric branches arises from the artery to the 
rectus inferior, which is given off from the carotid just before the 
latter crosses the ophthalmic artery (Fig. 13). After its exit from
