EXPLANATION OF PLATES. 



Plates I to VIII, figs. 1, 3, 5, 7, 9, 11, and 13, show the ampullary canals of the several species as 

 seen on removing the skin from the dorsal surface. The hyoid and superficial ophthalmic ampullae only 

 are shown, the outer buccal ampullae becoming exposed only when a deeper dissection is made. 



Plates II to VIII, figs. 2, 4, 6, 8, 10, 12, and 14, show the ampullary canals of the several species as 

 seen on removing the skin from the ventral surface. In most cases the hyoid and mandibular ampullary
