338 FAUNA ANTIQUA SIVALENSIS. 



The camassier consists of three lobes : the anterior one is a low 

 three-sided pyramid ; the middle one is an elevated acute lobe, as in 

 the Otter (it is partly broken off in the specimen), with a small tu- 

 bercle at the rear of the inner side, which is smaller than in the Otter ; 

 the rear lobe consisting of a flattened, nearly horizontal tubercle, 

 nearly plain, as in the Bear, but with a worn low maxillary process or 

 facet at the outside and inside. The tubercular or rear molar is an 

 oblong tooth with an obUque facet directed forwards ; then comes an 

 anterior lobe, and then a posterior lobe with a re-entering angle 

 between ; the posterior lobe consists of a single flattened point. The 

 corresponding tooth in the Otter is nearly circular in either central 

 point, from which four small facets are given off.
