provisionally referred until further material is received bearing 

 on their relationship to ^ . s. chevrieri and draco, of the S. W. and 

 S. of China.

 bushes."— If. P. A.

S . 1550, 1554, 1557. Imperial Tombs, 65 miles E. of Peking. 



As with most of the other Imperial Tombs animals the nearest 

 relationship of this striped rat seems to be with the Korean sub- 

 species, but in such a variable group the present series is not large 

 enough for me to be very positive on the point.

 ■certain open valleys." — M. P. A.

 stack in his threshing-ground." — M. P. A.
