Dk. Hikoshichiko Matsumoto, of the Tohoku Imperial 

 University, Seiidai, Japan, has recently been studying 

 the Fayiim collections of primitive proboscideans and 

 hyracoids in The American Museum of Natural History, 

 followed by a visit to the British Museum where he has 

 been making comparisons with the types of these mam- 

 mals, described by Dr. C. W. Andrew^s in his series of 

 papers beginning in 1901. In 1918 Doctor Matsumoto^ 

 published a series of five papers on the elephants, turtles, 

 sireniaii^,, cer\ idis, and bisons of Japan compared with 

 tho.^c ot India. He pointed out that the Japanese archi- 

 ])elag() was an integral part of the continent from the be- 

 ginning of the Miocene to the middle of the Pleistocene, 

 and that the period of separation seems to have dated 

 from tlie recent Pleistocene. Consequently its relations 

 with the animal life of southern China and with the more 

 distant peninsula of India are very close. 



The ancient Japanese proboscideans are chiefly of 

 three kinds, ot which the most numerous are the foVest-
