Willard: — Cranial Nerves of Anolis carolinensis 



PLATE 6. 



Fig. 16. Transverse section (No. 1175) through the pituitary body (not 

 lettered) and origin of the retractor oculi and bursaUs muscles. The roots of 

 nerves III and IV here have an intracranial course. Ramus frontalis V is 

 shown (/.) mesad to the origin of the protrusor oculi muscle. The insertion 

 of the m. pterygoparietalis on the pterygoid bone is shown. 



Fig. 17. Transverse section (No. 1226). This falls in a plane where few 

 main nerve rami are cut, as reference to the plotting will show. The ophthalmic 

 ganglion is shown as completely separate from the mandibular-maxillary part 

 of the Gasserian ganglion. Nerve IV is labelled V by mistake. 



Fig. 18. Transverse section (No. 1320) through the geniculate ganglion 

 and also showing a portion of the ganglion of nerve VIII. The otic capsule 

 and the tympanic chamber are just appearing. The insertion of m. pterygo- 

 sphenoidalis posterior on the pterygo-quadrate process {prt. pt-qd.) is showTi. 



Fig. 19. Transverse section (No. 1399) through the inner, middle and outer 

 ear, showing the root of nerve IX about to emerge from the cranium. The 

 chorda tympani, which is shown in this and preceding sections occupying a 

 position in the lower jaw, is here cut at a second place, where it is still in com- 

 bination with the motor part (hy-rnd.) of nerve VII, although its components 

 are distinctly segregated on the lateral side of the. hyomandibular ramus.
