i8 9 6. THE TEETH OF FISHES. 391 



The substance of this article agrees, in the main, with the 

 information supplied by the explanatory labels attached to a series of 

 preparations, illustrating the dental system of fishes, recently added 

 to Sir William Flower's educational collection, or " Index Museum," 

 in the entrance hall of the Natural History Museum. My grateful 

 acknowledgments are due to Sir William Flower for kindly per- 

 mitting the reproduction of several of the specimens to illustrate this 

 paper.
