Tho skull of the Z>. ursinus is short, very broad, and 
somewhat depressed; the great breadth is produced by the 
bold arch formed by the zygoma, near the posterior root of 
which the skull is broadest, and from that point it gradually 
tapers to the front. The temporal region is much contracted, 
and the sagittal crest considerably elevated, circumstance* 
which, combined with n strong zygoma, much arched in the 
horizontal direction, and nlso in the vertical, indicate great 
power in the muscles which work the lower jaw. The 
interorbital space is broader than in other Dasyuri, and the 
frontals tlirow out a distinct post-orbital process; a smaller 
post-orbital process arises from the innlar bone 1 . The 
posterior palatine openings are of moderate size, and remote 
from the hinder boundary of the palate, being situated 
opposite the interspace of the second and third true molars. 
1 In having a small post.orhit.il proceas to the frontal and malar bon«, 
Dasyurus macula tun approaches most near to the Ursine sjtrrics.
