willard: cranial nerves of anolis carolinensis. 109 



EXPLANATION OF PLATES. 



All figures are from A7iolis carolinensis. The projection drawings, figures 

 4, 5, and 6, and the drawings of transverse sections are from the same series 

 of sections (designated "Anolis trans. 30")- In figures 4, 5, and 6 the outlines 

 of the head, the brain and the eye are indicated. The places of passage of the 

 nerves through bony foramina are indicated by cu-cles. The drawing from a 

 dissection, figure 7, is made to conform as nearly as possible to the size of the 

 projection drawings, although it was taken from a somewhat larger specimen. 



Note. — Since the nerves and muscles are readily distinguishable in the 

 figures, the abbreviations mu. (for muscles), n. (for nerve) and rm. (for ramus) 

 are omitted in text and plates. The colors used have the following meanings : —
