Ehinoceros leptorhinus (E. megarhinus). 



Fio-s. 1 and 2. Represent the penultimate and last upper molars of S. 

 leptorhinus, about three-fourths of the natural size, and are taken

 obtained by Dr. Falconer at Stuttgart. The original teeth are 

 those upon which Jager founded his Ehinoceros Merchii. The 

 casts are now in the British Museum.
