. MERRIAM: THE FAUNA OP RANCTIO LA BREA. 261 



this specimen represents a young individual, the permanent dentition had been 

 complete and there is no reason to believe that the form and proportions of 

 the skull would have changed materially in later life. Of the dentition only the 

 superior carnassials have been preserved. These teeth have approximately the 

 size of those in C. ocliropus, but appear slightly thicker. A number of minor 

 differences between this specimen and typical representatives of the known 

 coyotes may have specific or subspecific value, but their estimation is not 

 possible with any degree of satisfaction when only one specimen is available 

 for comparison. 



It is to be hoped that other material representing this form may be ob- 

 tained so that some conception of the outlines of the body may be possible.
