 WHITE-FOOTED RACCOON-FOX. 



Type locality. Near Vera Cruz, State of Vera Cruz, Mexico. 



Genl. Char. Size large, color dark, feet white. Skull long, nar- 

 row, nasals pointed posteriorly (rounded in B. astutus and B. a.

 posteriorly to an equal extent as that of B. astutus; the pterygoid 

 fossa is long and rather broad, and the processes of the pterygoids are 

 thickened and heavy, very different from the slender processes of the 

 species compared; infraorbital foramina very large and triangular in 

 shape; palate anteriorly much broader for its length than either of 

 the other forms; postorbital processes short.

 base and tipped with black, the dark color predominating to such an 

 extent on the dorsal region that this part seems in certain lights all 

 black; sides of neck and body slightly paler; top of head nearly black 

 like the back, mixed slightly with white and buff hairs; above the
