obtained by Mr. C. H. McCharles from the Miocene six miles 

 north of Santa Ana. It may represent a new species or it may 

 be inseparable from Carcharodon branneri. The whole tooth 

 must have been three or four inches high, and its thickness must 

 have been fully an inch, or nearly half the breadth of the tooth 

 at base. The tooth is nearly flat on the inner edge, and very con- 

 vex on the outer edge. The serrae are small and close set. About

fifty are seen on the fragment of one side. This indicates that 

 about one hundred and twenty must have existed on each side, a 

 number comparable to that seen in the huge Carcharodon megal- 

 odon of the Atlantic Miocene. But in that species the tooth is 

 much flatter and less elevated on the median frontal edge. 



Still another tooth, referable to Carcharodon branneri, is from 

 Miocene rocks, Oil City. It is two and one-half inches high, 

 rather narrowly trangular, with wavy edges, incurved tip and 

 fine serrations, about seventy in number, on each side. 



The following analysis of the characters of the California 

 species of Gareharodon may be found convenient :
