Dlstribittloii. — Mountains south of Fort Yukon, about the head 

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

 Bristol bay, Alaska. 



Among the mammals secured by me in Alaska were three 

 specimens of Lagomys which ap[)ear to belong to an undescril)ed 

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

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

 Yukon, ])y the Indians of that district. 



Mr. McQuesten informed me that the Indians rejDort these 

 animals as common everywhere in the highest ranges south of 

 Fort Yidcon, 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,
