APLODONTIA LEPORINA, Rich. 



Sewellel; Shotw'l. 



Baird, Gen. Rep. Mammals, 1857, 353. 

 St. Ch. — Size of muskrat. Tail scarcely appreciable. Color reddish brown. 



Three specimens collected at Steilacoom — (11, 93, 92.) 



They are found in considerable numbers on the Cowlitz rivers, as well as in other localities 

 near here. Being about the size of muskrats, their skins were formerly palmed oif to the 

 Hudson Bay Company's agents by the Indians as skins of that animal, thereby frequently 

 deceiving the new and inexperienced employes of the company. Mr. Gibbs (who presented 

 me with the specimen sent) has handed me the following notes concerning it : 



"The specimen I send you was obtained at Seattle, where it was killed in a garden. Its 

 name, in the Nisqually language, is Showt'l, (Showhurll, Suckley.) Color gray; hair short and 

 coarse; legs short; eyes small; tail almost wanting. This animal burrows extensively in the 

 ground. It chiefly frequents spring heads in rich moist places, and is found as far up as the 

 dividing ridge of the Cascade mountains and on both sides of the divide. I noticed their bur- 

 rows in 1853 at the top of the main Yakima pass. Near their abodes were small bundles of 

 some herb or plant cut with nicety and laid out on logs to dry or wilt. The Indians trap them, 

 and value their meat very much as food." 



The Nisqually Indians formely made garments by sewing together a number of the dried 

 skins of this animal. They are caught generally by traps resembling in action our "figure 

 4" traps. 



CASTOR CANADENSIS, Kuhl. 



Beaver. 



Baird, Gen. Rep. Mammals, 1857, 355. 



Milk river. Neb. 



DIPODOMYS PHILLIPII, Gray. 



Baird, Gen. Rep. Mammals, 1857, 413. 



Sp. Ch. — Above yellowish brown ; beneatli white, with a white stripe across the thighs. Tail much longer than the body ; 

 black, with a white stripe on each side. 



Walla- Walla, 1854, No. 51. Called Sim-tup-tup by the Wasco Indians. They are also 

 found near the Dalles, at the bases of the eastern spurs of the Cascades mountains. 



The Indians say that they find them most plentiful about the berry patches on the eastern 

 slope of the Cascades. That from Walla-Walla was probably found in the Blue mountains.
