Fig. 1 : Exterior and top view of the right lower jaw of the 
type specimen. Approximately two-fifths natural size, the full 
length of the specimen as preserved being 260 mm. Fla. Surv. 
coll. No. 6856. 
The lower margin is convex and the jaw has great depth below 
the molars. The canines are extraordinarily large; the molars are 
greatly developed; the premolars are reduced in number as well as 
in size, only two being present; of these the anterior premolar, 
located just behind the canine is wanting in this specimen although 
its place in the jaw is indicated by an alveolus. Pm 4 is relatively 
large, the anteroposterior measurement being fully one-half that 
of M j. 
Fig. 2 : The molars and Pm 4 , natural size. The largest tooth 
of the series is the carnassial, AIAs in the old world species of 
the genus the paraconid and protoccnid are large and although 
rather thick afford an effective shearing blade. The metaconid is 
reduced and is placed well behind the protoconid. The hypoconid 
is large and receives heavy wear, while the entoconid is reduced 
The heel or talonid of AI , is wide exceeding the width of M 2 , in 
this respect differing from modern bears in which M 2 is the broad¬ 
est tooth of the series.
