MBRRIAM: THE FAUNA OF RANCHO LA BREA. 245 



individuals from Rancho La Brea. This may have been due in part to crush- 

 ing, as the specimen was much broken. The measurement of the canine is much 

 smaller than that in the larger individuals from Rancho La Brea, but was 

 evidently taken somewhat higher up on the cone of the tooth. Considering 

 the amount of variation known in the specimens at Rancho La Brea, there 

 seems to be good reason for including both the Livennore Valley and Tulare 

 County specimens in the group of Cants dims.

A fragment of a large wolf jaw (no. 5018) obtained in the Pleistocene 

 deposits of Potter Creek Cave, Shasta County, California 21 shows some of the 

 characters of Canis dims, as is indicated in the table of measurements below. 

 The inferior carnassial is larger than that of the Recent wolves, but the heel 

 is much narrower than in the typical G. dims, and the inferior premolars are 

 relatively very small. The only specimen known is so fragmentary that final 

 judgment as to its affinities should probably be withheld until better material 

 can be obtained, but there does not seem to be sufficient evidence available to 

 warrant definite separation of the Potter Creek form from the group of G. 

 occidentalis.
