WILLARD: — Cranial Nerves of Anolis carolinensis. 
PLATE 4. 
The sections represented in Plates 4-7 were selected at intervals through th 
series from which the projection drawings (Plates 1 and 2, figs. 4-6) were made 
The scale included in these drawings (Figs. 4, 6) shows the position of every 
hundredth section in the series. The planes of the sections shown in figure: 
8-24 may be determined by referring their numbers to this scale. Branches 
of minor importance which are not included in the plottings may appear in thy 
sections. No importance can be placed on a close comparison of the relative 
diameters of the nerves. These have suffered shrinkage to a different degree 
in different parts of the head and are represented approximately as they appeal 
in the sections, while they are for the most part enlarged and made uniform ir 
the plottings in order to demonstrate their components. The sections were 
drawn as projected by the camera and are accurate in respect to those struc. 
tures which are considered. 
Fig. 8. Transverse section (No. 130) anterior to external nares. The space 
between the nasal cartilage and the premaxillary bone is filled with pericapsular 
vascular tissue. The median palatine rami are here united. The sublingual 
gland opens by three ducts (one median, two lateral) anterior to this section. 
Labial glands open by numerous ducts. The mucous membrane in the floor 
of the mouth has numerous taste buds located between the gland openings and 
in the epithelium just median to the upper and lower jaws. 
Fig.9. Transverse section (No. 319) through nasal organ, showing externa 
and internal nasal chamber and external nasal gland. The tongue is cu’ 
through the region of the greatest development of the lingual papillae, the ou’ 
lines of which are represented somewhat diagrammatically. The muscle fiber: 
extend to the ends of these, which are provided with long protruding epithelia. 
cells. The taste buds are seen along both upper and lower lingual gum a 
points indicated (gm. gus. l.). No taste buds were observed on the papillae 
A single taste bud was found near the median line in the roof of the mouth 
while on the floor of the mouth they appear to be limited to the lingual gum. 
Fig. 10. Transverse section (No. 579), through ethmoidal ganglion ani 
internal nares, just anterior to the orbit and the larynx. In addition to th 
series of taste buds found in section No. 319, they appear along the latera’ 
border of the tongue in the stratified epithelium between the openings of th 
tubular glands. . 
Fig. 11. Transverse section (No. 659) cutting into the anterior wall of th 
eyeball and through the Harderian gland. The muscles at the root of th’ 
tongue are diverging to each side of the larynx, which is here cut through th 
glottis. The two laryngeal muscles appear.
