running outward and forward above the buccalis and one run- 
ning outward and forward below it. The seven branches that 
lie above the buccalis form several anastomoses with each other 
and accompany approximately the branches of the buccalis to 
organs 5 to 10, inclusive. In this relation to the buccalis they 
agree with the branches of nerves a, c, d, and e, which accompany 
approximately the branches of the buccalis to organs II to 14. 
The one branch that lies below the buccalis (#st.mx) leaves the 
maxillaris about opposite the buccal branch to organ 8, and is 
by far the largest branch of the nerve. It runs outward and 
downward and then forward across the upper surface of the 
third and fourth divisions of the levator maxillae superioris and, 
near the front edge of the fourth division of that muscle, breaks 
up into several branches. In the specimen used for illustration 
there were four of these terminal branches on each side of the 
head. Three of them turned outward and backward to supply 
the inner and outer surfaces of the maxilla, the other continuing 
forward under the front articular end of the maxillary bone 
toward the front end of the head, and breaking up into several 
branches all of which lay above the palatine and vomer and 
below the premaxillary. At the point where the main nerve 
breaks up into its four terminal branches it lies external to and 
close to the r. palatinus posterior facialis with which there is an 
interchange of fibres or partial anastomosis. This anastomosis 
is undoubtedly the one which in Cyprinidae, according to Sage- 
mehl, represents unquestionably the ganglion sphenopalatinum 
of higher animals (No. 107, p. 558). 
The main maxillaris superior leaves the orbit under the pre- 
orbital process and between the third and fourth divisions of 
the levator maxillae superioris close to their origins. On the 
left side of the head it passed with the buccalis through Lms4 
and a branch was sent outward and forward between the two 
heads of that muscle. The main nerve then runs forward 
above the articular head of the maxillary and separates into two 
main branches and other smaller ones. One main branch runs 
forward and downward, sending one branch backward and down- 
ward along the anterior part of the lower edge of the maxilla, 
and others forward, and forward and inward to the tissues
