This species differs considerably in color from either L. 

 trimucronatus or L. alascensis, and still more in cranial details. 



Of this species Mr. Anderson says: "The short-tailed yel- 

 lowish voles taken at Telegraph Creek inhabited a long, 

 rather dry little valley near the top of the 'Summit.' At 

 the time I attempted to trap them, a light snow fell during 

 the first night, and in the morning we saw a number of places 

 where these animals had burrowed through the snow and 

 made long winding trails to the surface, not merely tracks, 

 but trails, as if they had dragged their bodies through the 

 soft snow. I followed one of these for more than twenty 

 yards. It ended in a little tunnel in the snow." At Level 

 Mountain he says: "The small number of the short-tailed 

 yellowish voles which I took here was from holes beneath 

 rocks imbedded in the moss and lichen in places back from the 

 streams, but nevertheless often very damp." 



The following schedule is of interest as showing the relative 

 abundance of the different species of Muridae at the five 

 principal localities in the Telegraph Creek region where col- 

 lections were made, as from Mr. Anderson's report it is evi- 

 dent that the collecting was indiscriminate at each of the 

 localities. The time spent at each was of course unequal, but 

 the ratio of abundance, as indicated by the specimens taken, 

 is not thereby affected.
