WILLARD: CRANIAL NERVES OF ANOLIS CAROLINENSIS. 57 
_ showed the continuity of the cutaneous fibers, which is indicated in 
Plate 3, fig. 6, by dotted lines. This ramus divides into several 
‘branches to supply the skin at the posterior angle of the eyelids, and 
also the posterior half of the lower eyelid. (c) Another branch (mz.’), 
similar to (mx.?), runs forward to supply the anterior half of the lower 
eyelid. This shows an anastomosis with mz.? (Plate 3, figs. 6, 7). 
(d) A branch (mz.*) which passes into the cavity of the ventral bony 
arch of the orbit supplies the skin over it as far forward as the anterior 
limits of the orbit. The rest of the nerve (2f’orb.) now passes cephalad 
across the orbit to enter the infraorbital foramen, an opening bounded 
by the maxillary, lachrymal and jugal bones (Plate 1, fig. 1, for. 2f’orb.). 
Before entering this foramen it gives off cutaneous fibers at two points, 
which, however, are not free from connection with the palatine rami 
and are indicated only by the somatic sensory component (yellow) 
included in these palatine rami. One of these combines with the 
visceral components of VII to form a good sized branch (pal. /.), 
which passes cephalad under the fold of epithelium on the median side 
of the maxillary bone. This fold is rich in tubular glands and taste 
buds (Plate 4, figs. 9-11). The other passes mesad to meet the inter- 
mediate ramus of the palatine (pal. 2’m.), and the combined nerve 
comes out to the mucous membrane farther cephalad, where it con- 
tinues the innervation of the lateral field (Plates 2, 3). 
Ramus alveolaris superior (alv. su.). This is the term applied to 
the intra-maxillary portion of the maxillary nerve. In Anolis its 
distribution is wholly to the integument at the side of the jaw, which 
it reaches through numerous foramina that are indicated in the skull 
(Plate 1, fig. 2), and to the teeth, as described more fully for the lower 
Jaw. 
| Connection of the sympathetic with the ramus maxillaris trigemine. 
| There is one well defined and constant sympathetic ganglion on the 
main trunk of the maxillary nerve. This, because of its position at 
| the beginning of the infraorbital course of this nerve, is known as 
the ifraorbital ganglion (Plate 2, 3, figs. 4, 7, gn. 2f’orb.). It is 
| much flattened laterally (Plate 5, fig. 14), the flattening being due, 
no doubt, to its location. It is connected with the main superficial 
; sympathetic ramus of the head by a strand of non-medullated, or 
very slightly medullated, fibers. The medullation is so slight that 
the connection is very difficult to establish in the sections, the dis- 
section preparations, however, leave no doubt on this point. It is 
| impossible to tell to what extent recurrent fibers may connect with 
the trigeminal ganglion. It is certain, however, that the main
