catch in traps, and the greater number, composing the series 

 we secured, were taken in butterfly nets. One of the men 

 would go carefully through the grass holding the net before 

 him, and when one of the little animals would disclose, his 

 presence by leaping forward, the net holder would throw the 

 net at him, frequently following it himself with his whole length 

 on the ground. In this way as many as seven were taken in one 

 afternoon. Once in the net, the mouse made no effort to escape, 

 and was easily secured. It is the largest species of the genus, 

 and while resembling Z. princeps, Allen from Colorado, is differ- 

 ently colored from that species, and readily distinguishable. 

 We found this kangaroo mouse at timber line, and some speci- 

 mens were taken at the farthest point we reached. One very 

 fine adult, having been picked up dead in our camp at Boulder 

 Lake, presumably stepped upon, or struck by a horse as it was 

 sitting in the thick grass. It is a very attractive little creature, 

 the immaculate white of the under parts presenting a pleasing 

 contrast to the dark back and buff sides. 



Twenty - six specimens: McDonald's Ranch, i; Johnson's 

 Ranch (Elwah River), 6 ; Sieg's Ranch (Elwah River), 9 ; 

 Boulder Creek, 3 ; Happy Lake, 5 ; Boulder Lake, 2. 



The skull as shown below exhibits the inferior surface, and 

 the upper tooth row enlarged six times.

This handsome hare was rather plentiful in all parts of the 

 mountains visited by us. The settlers state that it never turns 

 white in winter, and certainly up to the latter part of October, 

 when there was plenty of snow around, they presented no indi- 

 cation of changing the hues of their pelage. Those taken were 

 caught in cyclone traps, very few opportunities ever being 

 afforded for the use of the shot gun. They were, perhaps, more 

 abundant near timber line ; at least we took a number of speci-
