In the portion of the maxillary present there is nothing to dis- 

 tinguish the Cape Blanco form from Elasmognathus bairdii. 



The molars do not agree exactly in all characters with those 

 of any species available for comparison. Prom Tapirus ter- 

 restris they differ considerably in the much smaller parastyle 

 of M 2 . From T. roulini they are distinguished by the relatively 

 smaller size and more nearly quadrate form of M 2 . From T. 

 ind/icus, they are separated by the more nearly square cross- 

 section of M 2 , and by the tendency to development of an external 

 cingulum on the outer side of the metacone pillar of M 2 . The 

 Cape Blanco form approaches Elasmognathus bairdii in the 

 nearly quadrate form of M 2 , and in the presence of a weak 

 cingulum on the outer side of the metacone pillar of M 2 . There 

 is also a faint suggestion of a tubercle on the inner side of M 1 

 between the protocone and hypocone pillars as in E. bairdii. It 

 seems possible to distinguish the Cape Blanco form from E. 

 bairdii by the weaker external cingulum on the outer side of M 2 , 

 by the absence of a cingulum on the corresponding region of M 3 , 

 and by the absence or imperfect development of the tubercle on 

 the inner wall of the molars between protocone and hypocone. 

 There is also a less distinctly noticeable evenness of the molars 

 in form and size in the Cape Blanco form than in the Recent 

 E. bairdii. 



With Tapirus haysii Leidy from the Pleistocene of southern 

 and eastern United States it is not possible to make an entirely 

 satisfactory comparison, as no good figures are available. The 

 specimen figured by Leidy from the Brasos River near San 

 Pillipe, Texas, is somewhat worn and the diagnostic characters 

 are not clearly shown. The dimensions are very near those of 

 the Cape Blanco specimen. This specimen is evidently near 

 Tapirus haysii, and may be referred to tentatively as Tapirus, 

 near haysii calif ornicus.
