REPORT UPON THE MAMMALS COLLECTED ON THE SURVEY. 
CHAPTER I. 
REPORT BY J. 6. COOPER, M. D. 
NEOSOEEZ NAVIGATOR, Cooper. 
Baird, Gen. Rep. Mammals, 1857, 11. 
Sp. Ch. —Fur much longer than the ears. Palms and soles margined by a fringe of bristles. Hind feet nearly as long as tha 
skull. Tail one-half longer than head and body. Color above, dark sooty brown, mixed with hoary ; beneath, greyish white ; 
tail silvery white beneath. Head and body 2.10 ; tail 3. 
But one specimen of this species was obtained during tbe expedition ; this, according to tbe 
label now attached, was found at Fort Vancouver, but I am inclined to consider this a mistake, 
and that it was really taken while swimming under water in a lake near the summit of the 
Cascade mountains, August 31, 1853. 
SOREX VAGRANS, Cooper. 
Baird, Gen. Rep. Mammals, 1857, 15. 
Sp. Ch. —Third upper lateral tooth smaller than the fourth. Above, olive brown, washed with hoary; beneath, dusky 
yellowish white ; sides a little paler than the back. Head and body 2 inches ; tail 1.75. Hind foot about .47 of an inch. 
Specimens were obtained at Shoalwater Bay, W. T. 
SCALOPS TOWNSENDII, Bach. 
Oregon Mole. 
Scalops townsendii, Bach. J. A. N. S. Ph. VIII, 1839, 58. 
Aud. & Bach. N. A. Quad. Ill, 1853, 217 ; pi. cxlv. 
Baird, Gen. Rep. Mammals, 1857, 65. 
Sp. Ch. —Teeth 44. Eye small, but not covered by the integument. Tail rather scantily haired. Nostrils opening on the 
upper surface of the tip of the snout. Palm large and broad. Color nearly black, with faint purplish or sooty brown reflection. 
(Sometimes, perhaps, glossed with silvery ?) 
Moles are not common in any part of the Territory I have visited. Two specimens were 
obtained at Shoalwater Bay, where they burrow more like the gophers than the S. aquations, 
throwing up little mounds at a yard or two apart, though they sometimes in soft ground formed 
continuous galleries just beneath the surface.
