DESCRIPTION OF A NEW SPECIES OF LAGOMYS 

 FROM ALASKA .* 



BY E. W. NELSON. 



Lagomys collaris sp. nov. 



THE COLLARED PIKA. 



Lagomys princeps Nelson and True, Report upon Natural History Col- 

 lections in Alaska, pp. 273, 274, 1887 (not Richardson). 



Type collected about 200 miles south of Fort Yukon, Alaska, near the 

 head of the Tanana river. No. Uilf. U. S. National Museum. Col- 

 lected by E. W. Nelson, 1880. (Original No., 164.) 



Distribution. Mountains south of Fort Yukon, about the head 

 of the Tanana river, to the Chigmit mountains, near the head of 

 Bristol bay, Alaska. 



Among the mammals secured by me in Alaska were three 

 specimens of Lagomys which appear to belong to an undescribed 

 species. They were obtained, at my req uest, through the kind- 

 ness of Mr. L. N. McQuesten, from the mountains south of Fort 

 Yukon, by the Indians of that district. 



Mr. McQuesten informed me that the Indians report these 

 animals as common everywhere in the highest ranges south of 

 Fort Yukon, where they are usually found above timber line. 

 From native accounts their habits appear to be identical with 

 those of the more southern species. I showed the skins to a fur- 

 trader who had lived for many years at Kolmakovsky Redoubt,
