talis and the nasalis, Varanus agrees with Anolis in so far as no 
branches are given off from the nasalis between the ciliaris and the _ 
posterior extremity of the internal nares, where, as she states, the “r. — 
comm. cum ramo platinus VII”’ is “composed of at least two distinet 
fiber bundles,’ which communicate with palatine VII; then follow 
the same divisions as noted for Anolis anterior to this, i. e., “r. latera- 
lis” and “r. medialis,’ these having much the same distribution as in 
Anolis. To the medialis are assigned the following branches, r. pre- 
maxillaris superior (dorsal) and r. premaxillaris inferior, these inner- 
vating the skin of the nose and the lips. | 
Ethmoidal ganglion (gn. eth.). This is a ganglion of oval form and 
one fourth mm. in length, which lies closely applied to the ventral 
and lateral sides of the nasalis nerve (Plates 2, 3; Plate 4, fig. 10). 
The ganglionic cells do not entirely surround this nerve, and there is 
no passage of medullated fibers from nerve to ganglion. The gan- 
glion is in connection with the median branch of the palatine nerve 
through communicating bundles of fibers; these fibers are also accom- 
panied by sympathetic ganglion cells, which form a sort of column of 
cells extending from the side of the ganglion opposite the nasalis — 
nerve to the palatine ramus (Plate 4, fig. 10). A dissection of this 
ganglion and its connections, mounted in balsam, shows some fine, 
lightly medullated fibers from the stalk passing both caudad and 
cephalad in the palatine. The almost complete lack of medullated 
fibers among the cells indicates that the ganglion has to do largely with 
non-medullated fibers. A very small bundle of such fibers joins the 
ganglion on its posterior side close to the nasalis nerve. To what 
extent this ganglion may be in connection with non-medullated fibers 
of the nasalis, could not be determined, but Such a relation would 
appear to be the only explanation of the anatomical relations observed. 
The cells of the ganglion are smaller and less clearly defined than 
those of the cerebral ganglia, showing in this their sympathetic char- 
acter (Carpenter, :06). 
The ethmoidal ganglion occurs regularly in birds, as far as they have 
been studied, as a group of ganglion cells on the ophthalmic branch of 
V. Bonsdorff (’52) gave it the name of “ganglion ethmoidale,” and 
Rochas (’85) “g. orbitonasale.” In the goose Cords (:04, p. 59) de- 
scribes this gdnglion as being 1 mm. long and 4 to 3 mm. broad, and as 
having the same connections as we find in Anolis, i. e., with the ophthal- 
mic branch of V and the palatine branch of VII. There can be no 
doubt of the homology of this ganglion as described for birds with the 
structure to which the name has been given in Anolis. _
