1921] Grinnell: Two New Rodents from Eastern California 243 



Distribution. — Restricted so far as known to the higher parts of 

 the White Mountains, in extreme southeastern Mono County, Cali- 

 fornia; altitudes of occurrence, 10,300 to 12,400 feet; life zone. Boreal. 

 Material at hand 33 skins-with-skulls from localities as follows, all in 

 the White Mountains, Mono County : Big Prospector Meadow, 10,300 

 to 10,700 feet, 17 ; vicinity of McAfee Meadow, 11,300 to 12,400 feet, 16. 



Remarks. — ^When Mr. Arthur H. Howell worked up the American 

 marmots there were seven specimens from the White Mountains avail- 

 able to him ; but these were not in perfectly satisfactory condition, and 

 he referred them "provisionally" (Howell, 1915, p. 45) to his Marmota

flaviventris parvula. Now that he has seen some of my new material 

 (we made comparisons together at the National Museum in May, 1921), 

 he agrees with me that the animals from the White Mountains con- 

 stitute a recognizable subspecies. The real paucity of specimens now 

 lies with the Nevada form, parvula, of which there still are available 

 only the nine examples recorded by him and contained in the collection 

 of the Biological Survey.
