On Evidence of a New Species of Titanosuchus. 143 



smaller and rounder. Another difference is in the arrangement 

 of the anterior molars. In T. fcrox the line of the molars is 

 much on the inside of the large canine, but in T. cloetei a line 

 drawn along the inner sides of the molars also forms a tangent ta 

 the canine. The front of the jaw is also very much squarer in the 

 smaller species, owing to the canine being relatively further forward. 

 If a line be drawn across the front of the jaw at right angles to the 

 symphysis, the back of the canine lies -067 m. from the line and the 

 back of the 4th molar -116 m. 



The symphysis has a transverse diameter of "043 m., and a vertical 

 diameter (somewhat imperfect) of about -080 m. 



I have pleasure in naming the species after the donor, who has 

 presented some interesting fossils to the Museum.
