nized. It is much more like the high pitched note of some small bird 

 and lacks all the nasal tone so characteristic of our species. The old 

 animals, from July 1 to 25, were chiefly in the left-over winter pelage, 

 or in a ragged state of molt. The young were already nearly grown, 

 some of them molting the post-juvenal pelage and renewing into the 

 brown fall coat of the adult. Numbers were caught in rat traps 

 baited with rolled oats, a method I have never found at all successful 

 with various America-ti species. 



In the heavily forested mountains near Tapucha we found pikas 

 on the rocky tops, and even in dry rocky creek beds far below timber- 

 line. In these latter localities they seemed entirely out of place to 

 us, but were nevertheless fully at home. The specimens taken here 

 from August 7 to 10 are in full fresh fall coat. Our Tartar and 

 Kalmuk camp men called the pika ^ ' seen-d-staft' ." 



I beUeve that true 0. alpina, from which I have separated this 

 species, will be found to inhabit the Bia-Altai, the region north of 

 Lake Teletzkoi, and between the Bia and the Katun Rivers. There 

 is a specimen of alpina in the United States National Museum labeled 

 "Barnaul."

We met with this hare only in the Tapucha forests where, with 

 difficulty, we secured three specimens; a skin and skull of a male in
