CARNIVORA 



less convex throughout and in particular less bent downward 

 anteriorly ; depth of rostrum at level of front of carnassial 

 barely equal to distance from carnassial to front of premaxillary 

 instead of appreciably greater ; orbit larger and more widely 

 open posteriorly than in M. putorius, a peculiarity due chiefly to 

 the very slight development of postorbital angle on upper margin 

 of zygoma ; auditory bulla moderately inflated, irregularly almond- 

 shaped in outline, its width barely half its length, the meatus 

 slightly projecting but not tubular. 



Teeth. — The teeth are less robust but more prehensive than 

 those of Mustela putorius, the former peculiarity best shown by 

 the upper carnassial, the latter by the premolars seen in profile 

 when jaws are closed. In the upper carnassial the transverse 

 diameter behind inner lobe is distinctly less than in M. putorius, 

 the anterior cingulum cusp is better developed, the main cusp is 

 lower, and the posterior cutting edge has a concave or nearly 

 horizontal posterior portion rather longer than the abruptly 

 sloping anterior portion (in M. putorius the cutting edge when 

 unworn slopes directly from apex of main cusp to base of 

 posterior cusp). Small premolars fitting closely against each 

 other when jaws are shut ; posterior lower premolar cutting 

 against anterior surface of upper carnassial and posterior surface 

 of pm 3 , instead of being widely removed from carnassial and 

 fitting distinctly inside of pm 3 .
