SECOND EUROPEAN OIIGOCENE SPECIES, DESCRIBED BY 

 KIERNIK, 1913 



Titanotherium bohemicum Kiernik, 1913 



Cf. Menodus giganteus, this monograph, page 530 



Original reference. — Acad. sci. Cracovie Bull., ser. B, 

 vol. lOB, pp. 1211-1225, pi. 63, 1913 (Kiernik, 1913.1). 



Type locality. — Uncertain. The specimen, a frag- 

 ment of the lower jaw containing the third right lower 

 molar, was received with a lot of fossils from the dilu- 

 vium near Prague. It was supposed to have come 

 from the lime pits of Podbaba, near Prague, and to 

 have been sold by one of the workers in the lime pits

Fragment of a lower jaw with third right lower molar. After Kiernik. A, Outer side view; B, inner side view; C, top view, showing 

 the grinding surface of ms; D, front view, showing the exposed posterior roots of mj. Ahout one-fourth natural size. 



Diameter of second molar: 



Anteroposterior 71 



Transverse 41 



Diameter of third molar: 



Anteroposterior 99 



Transverse 43 



Space occupied by roots of third premolar (anteroposterior) 34 

 Space between fourth premolars (twice the distance of 

 fourth premolar from vertical plane through symphysis) - 60 

 Etymology. — assiniboiensis , in allusion to the geo- 

 graphic occurrence of the type. 



Present determination. — This species apparently be- 

 longs in the Brontotheriinae. It is smaller than 

 Brontotherium Tiatcheri. The nasals doubtfuUy referred 

 by Lambe to this species suggest those of Bronto- 

 therium curtum. 



to Herr Baumeister Kuchta (died 1910). He gave it, 

 along with other prehistoric specimens, to Herr 

 EoJanek, who in turn gave it to Herr Jira, who pre- 

 sented it to the Institute for Comparative Anatomy 

 at Prague. After carefully considering the possi- 

 bility that the specimen might have been of American 

 provenience the author, Herr Kiernik, inclines rather 

 to the view that it really came from Bohemia, al- 

 though not from Pfodbaba, but from the fresh-water 

 Tertiary deposits of Tuchofitz (northwestern Bo- 

 hemia). The well-known fauna of Tuchofitz is, 

 however, of lower Miocene facies. 



Type. — A lower jaw fragment containing the third 

 right lower molar. (See fig. 206.)
