formulas are as in Alticola, and the two distinguishing characters, 

 the large ears and peculiarly flattened skull, seem best considered as 

 subgeneric. 



Measurements of selected adult specimens of Alticola (Platycranius) strelzovi from the 

 Tchegan-Burgazi Pass, Altai Mountains, Siberia. 



APODEMUS NIGRITALUS Hollister.

 March 13. * 



Ten specimens from the heavy forests of Pinus cembra near 

 Tapucha, August 6-11. These were trapped in small grassy open- 

 ings in the woods, usually under logs or bushes. This species is 

 a member of the speciosus group, and is rather nearly related to 

 Apodemus peninsulse of Korea and northern China. It is readily 

 distinguishable from the smaller Apodemus sylvaticus tscherga, 

 which occurs in the same forests, by its much larger size, more 

 reddish coloration, the heavy supraorbital beads on the skuU, and 

 the presence in females of eight mammfe instead of six.
