Twenty-three specimens: i, Agness, Curry Co., 5,000 feet alt.; 

 8, Gardiner; and 14 Florence, Oregon. 



Of this species at Gardiner, Mr. Heller writes that it was "com- 

 mon everywhere on ridges and side hills. Bunches of freshly cut 

 ferns were seen about the entrances of the burrows. A few of the 

 fronds were carried into the burrows, but the greater part remained 

 in bunches at the entrance. The fronds were all cut near the root- 

 stock and were placed with their cut ends toward the burrow, usually 

 within a few inches of the opening. Burrows which were placed in 

 salal, were surrounded by freshly cut twigs of the shrub." At 

 Florence in addition to the ferns and salal gathered about the 

 burrows "Oregon grape" was also frequently present. I cannot sepa- 

 rate the example from Agness taken at a high elevation from the 

 present species.

Ten examples: 2, Nicasio; 2, Point Reyes (topotypes) ; 6, Eureka, 

 California. 



A few colonies of this species occur at Nicasio (which is appar- 

 ently its eastern limit), at the head of two or three canons in moist 

 places on the hillside. At Point Reyes, the type locality, only a few 

 burrows were seen, but the species was said to be much more common 

 on the coast slope of the hills which in places, are stated to be covered 

 with them. At Eureka this animal was "abundant in forests, on damp 

 hillsides, and along streams. It is said to live only in places where 

 it can burrow down to water. They seldom dig their burrows in culti-
