Notes on a New Fossil Mammal. 



By 



S. YOSHIWARA 



AND 



J. IWASAKI. 



With S Plates. 



In 1898 a Ibssil skull of a large mammal apparently of an 

 unknown type came into po.s.ses.sion of Mr. Iwasaki. Accordingly, in 

 the followino- year, Mr. Yoshiwara visited the locality where the 

 skull was reported to have been discovered, in order, if possible, to 

 ascertain its exact mode of occurrence. The place is called Togari, 

 situated in Kanigöri, province of Mino, and the rock in which the 

 fossil was found is a tufaceous sandstone belonging to the Xeogene 

 Tertiary, probably Miocene. In this sandstone Mr. Yoshiwara found 

 a specimen of a tooth belonging to the same inammal, a iact which 

 confirms the discovery of the skull in the same rock. The strata 

 lying considerably below the sandstone contain Vicarija callosa 

 Jenkins f and many other marine shells, which are generally 

 considered to be Pliocene. Associated with the above bones there are
