WILLARD: CRANIAL NERVES OF ANOLIS CAROLINENSIS. 67 
points sympathetic ganglion cells are to be found. When formed, the 
ramus is a mixed nerve containing some fine medullated viscero- 
sensory fibers from the palatine VII, some coarser medullated fibers 
of the cutaneous type from the maxillary V, and likewise non-medul- 
lated sympathetic fibers. The distribution of the medullated fibers 
of this ramus (Plate 4, figs. 9-11) is along the median side of the 
glandular gustatory strip (Plate 4, fig. 9, gm. gus. l.), which begins at 
the angle of the mouth and extends to the anterior end of the upper 
jaw. Posterior to the distribution of this ramus the glandular band 
is narrower and is innervated wholly from the ramus lateralis (Figs. 
10, 11); here however, it broadens. By the narrowing of the jaw the 
two rami (r. lateralis and r. intermedius) are brought closer together, 
until finally their terminal branches mingle (Plates 2, 8, figs. 4, 6; 
Plate 4, fig. 9). 
(c) Ramus lateralis (pal. |.). This, like the preceding, is a mixed 
ramus; but contains a larger proportion of cutaneous fibers. These 
are drawn off from the maxillary ramus at the anastomoses indicated 
in the plotting and dissection (an’stm. pal. l.). In the dissection 
(Plate 3, fig. 7) these anastomoses of the intermediate and lateral 
palatine branches with maxillary V are effected at the same point. 
The ramus lateralis passes cephalad along the median side of the 
maxillary bone and innervates taste buds and general epithelial sur- 
faces (Plate 4, fig. 10). As described above, it has a terminal area of 
distribution which is common to it and to the intermediate ramus. 
The relation between nerves V and VII, described here as the infra- 
orbital plexus, may be taken as representative of the group. About 
the only constant feature in the complex, however, is the palatine 
ganglion or the point corresponding to it. It is believed that this 
junction of V and VII would always disclose a ganglion if examined 
| 
microscopically, and the apparent importance of this ganglion as a 
structural feature in Hatteria (Osawa, ’98, p. 603, fig. 45) may be due. 
to the fact that the cells are clustered instead of being scattered along 
the nerve. The latter condition is probably due to the position of 
the nerve, compressed/as it is against the floor of the orbit. There is 
seen to be some evidence, from the character of the fibers in these 
anastomosing branches, to justify the acceptance, in a general way, 
(of Fischer’s (’52, p. 138, 139) distinction between a posterior and an 
| anterior anastomosis, the posterior being a “sling’”’ of the sympathetic 
system, while the anterior is a mixture of fibers from V and VII for 
‘distribution. Fischer did not recognize the sympathetic ganglia 
present in this region, but based his view on the proximity of the
