UNGULATA PERISSODACTYLA. 
Brojstotherid.®.^^ 
O. C. Marsh gives further particulars as to this remarkable Miocene 
family [r/. Zool. Rec. x. p. 14]. It was truly perissodactyle, though 
with affinities to the Dinocerata and Proboscidea. It was most nearly 
allied to the lihinoccrotidce, but had four sub-equal toes in the manus, 
and three in the pes. The naskls supported two large horn-cores placed 
transversely, canine teeth were present in each jaw, and the molars 
resembled those of CJialicotJierium. Sgmborodon, Cope \infra^ p. 14], = 
Miobasileus, Cope, = Brontotherivm. Leidy’s genera Titanotherium and 
Megacerops probably belong to this family. Am. J. Sc. (3) vii. pp. 81-85 ; 
Am. Nat. 1874, pp. 79-85, pis. i. & ii.
