106 NORTH AMERICAN FAUNA. [xo 16. 
Mustela caurina Merriam. Pacific Marten. 
Common in parts of the dense forests of Shasta, particularly on the 
east side, where many are caught every winter by trappers. We did 
not succeed in obtaining a specimen, although a line of ‘meat traps’ 
was kept out fully a month, Still, fresh tracks were seen in the mud 
along Squaw Creek a short distance below camp by Vernon Bailey. 
Fic. 35.—Marten. (Drawn by Ernest 8. Phompson.) 
Mustela pennanti Erxleben. Fisher. 
Said to occur in the dense forest on the east side of Shasta, whence 
skins are brought to Sisson for sale nearly every winter. C. H. Town- 
send obtained two on McCloud River, about halfway between the 
mouth of the river and Mount Shasta, in February, 1554. 
Lutra hudsonica Lacépede. Otter, 
Occurs Wong the upper Sacramento and McCloud rivers; not noted 
by our party. 
Putorius arizonensis Mearns. Mountain Weasel, 
Apparently not common. lily in August three were caught in 
Mud Creck Canyon, near the mouth of Clear Creek, in traps set in 
alplodontia runways. It is quite possible that another species, P. 
canthogenys orcgonus, inhabits the low country about the base of the 
mountain. 
Bassariscus astutus raptor (Baird). Cacomistle; Ring-tail Cat. 
Not observed by us, but doubtless occurs about the basal slopes of 
Shasta, as it has been captured both north and south of the nountain.
