Speciyjiens examined. — Nine, all from the type locality. 



Remarks. — One of the specimens of this species ( $ No. 101617, 

 August i) is in very abraded pelage, the longer hairs of the back be- 

 ing for the most part worn away. Yet there is no appreciable change 

 in color. The tail has become a dark, indefinite brown, but the re- 

 mainder of the pelage retains its colors practically unaltered.
