as subspecifically distinct, and would suggest the name, *Neo- 

 toma cinerea columbiana for it. 



Twenty-three specimens in all were captured, but few of them 

 were old individuals, the greater portion being young or young 

 adults. This species is apparently the darkest in color of the 

 bushy-tailed rats. 



Twenty-three examples : Campbell's Ranch, Elwah River, i; 

 Boulder Creek, 7 ; Johnson's Ranch, Elwah River, i ; Happy 

 Lake, 14.

This distinct species was quite scarce, and during all our stay 

 in the Olympics we only obtained six specimens. It seems to be 

 a dweller of the high ranges, as we first met with it at Happy 

 Lake just below the timber line, and saw no trace of it anywhere 

 at lower levels. It is quite a different looking animal from P. 

 orophilus, the species I compared it with, being darker and 

 inclined to a more reddish hue. The ears are quite prominent, 

 as is usually the case with members of this genus, stand well out 

 of the fur, and are large for the size of the animal. The tail 

 varies slightly in length among individuals, the average of the 

 six examples possessed being 28 mm., a little longer than that of 

 the type. The longest tail is 31 mm. and the shortest 28 mm. 



Six specimens: Happy Lake, 5; Boulder Lake, i. 



The figures show the inferior surface of the skulls of the 

 present species and P. orophilus, natural size, and also the upper 

 tooth row of each, something between six and seven times 

 greater than natural size.
