PLATE 3 
A continuation of figures of plate 2. All references are to the right side of 
figures. 
Fig. 8 passes through middle of dorso-lateral VII and through the geniculate 
ganglion at the point where the placode was attached to the epidermis. The 
area blocked out in this figure lies in the middle of the series of figures on succeed- 
ing plate (fig. 18). 
Fig. 9 passes through the posterior end of dorso-lateral VII and through the 
middle of ventro-lateral VII. The geniculate is cut posterior to the placodal 
ganglion. 
Fig. 10 passes through the middle region of the auditory capsule and through the 
IX ganglion at the point of origin of its visceral trunk. 
Fig. 11 passes through the epibranchial placode of the first branchial ganglion 
of X and the root of the lateralis X ganglion. 
Fig. 12 passes through the middle of the lateralis X ganglion and through the 
visceral X just anterior to the epibranchial placode of the second branchial gan- 
glion of X. The visceral root of X is cut in this section. 
Fig. 13 passes through the posterior end of the lateralis X ganglion posterior 
to the posterior end of visceral X. The visceral root of X is cut in this section 
quite close to the medulla.
