t'ANIS ANDERSONI, n. sp. 



Type specimen no. 12249. Univ. Calif. Col. Vert. Palae., from 

 the asphalt beds of Rancho La Brea near Los Angeles, California. 



This species is represented by a young adult skull of a small 

 wolf with a much smaller and also relatively broader skull than 

 C. orcutti. Though this specimen represents a young individual 

 it differs so much in form from all the other known species in 

 this region that it seems necessary to refer it to a distinct specific 

 group. Measurements.

CANIS OCCIDENTALIS FUELONGI, n. var. 



Type specimen no. 11283, Univ. Calif. Col. Vert. Palae., from 

 the asphalt beds of Rancho La Brea near Los Angeles. California. 



There are in the Rancho La Brea collections several frag- 

 mentary specimens representing a wolf considerably smaller than 

 the smallest individuals of Can is indianensis type, and evidently 

 representing a form closely related to the existing North Amer- 

 ican timber wolves. In the details of structure the teeth are. 

 however, distinguishable from those of the living forms. 



In the type specimen, which is a right maxillary with the 

 molars and carnassial. the anterior region of the palate seems 

 relatively narrow, though perhaps not narrower than in the ex- 

 isting species. 



The superior carnassial is massive and the deuterocone seems 

 to have been small. On M 1 the hypocone is much larger than 

 in C. indianensis and has approximately the same size as in C. 

 pambasileus. The anterior end of the hypocone cusp is extended 

 around the anterior side of the protocone as a faint ridge, in- 

 stead of beino- interrupted on the antero-internal portion of the
