Great Basin Spotted Skunk. 
Spilogale saxatilis Merriam, A^. A. Fauna, No. 4, p. 13 (1890). 
Type locality. — Provo, Utah. 
Measurements. — Total length, 1 7.75 ; tail vert., 6.00 ; hind foot, 2.0. 
Description. — Markings as described for genus, terminal third 
of tail white. Auditory bullae and mastoid capsules not much 
inflated, and not very noticeable from above; brain-case flattened; 
fronto-parietal region depressed to general level of upper surface of 
skull; postorbital constriction pronounced; teeth rather small; 
ridge on mastoids pronounced ; posterior end of skull lower than 
in tenuis, and when skull is viewed from behind the brain-case 
shows quite high above the lambdoidal ridge. This is one of the 
characters distinguishing this species from 5. tennis, and others 
are the much less inflated bullae and mastoid capsules, more 
pronounced postorbital constriction, and ridge on mastoids.
