showed the continuity of the cutaneous fibers, which is indicated in 

 Plate 3, fig. 6, by dotted Hues. This ramus divides into several 

 branches to suppl}^ the skin at the posterior angle of the eyelids, and 

 also the posterior half of the lower eyelid, (c) Another branch (mx.^), 

 similar to (nix.-), runs forward to supply the anterior half of the lower 

 eyelid. This shows an anastomosis with vix} (Plate 3, figs. 6, 7). 

 (d) A branch (mx.'^) 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 {if 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. l,for. if 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. I.), 

 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 {yal. i'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 {ah. 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 loith the ramus maxillaris trigemini. 

 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 infraorbital ganglion (Plate 2, 3, figs. 4, 7, gn. if 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 meduUated, 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
