Felis oregonensis oregonensis Rafiuesque 

 Northwestern Cougar 

 One specimen (skin and skull, no. 12871) of mountain lion was 

 gotten by George Knowles at Hay Fork. Trinity County, and sent 

 in after our return. 



Lynx fasciatus Rafinesque 

 Barred Wildcat 

 As the status of the various species of Lynx seems to be rather 

 uncertain I have referred our specimens (four from Helena and 

 Tower House, nos. 12872-12875) to the species first described. 

 They certainly belong to the fasciatus group, if that name is to be 

 applied to the more northern form of Lynx, rather than to the 

 lighter-colored calif ornicus from the south; but they are not as 

 dark as some specimens in the Museum collection from Humboldt 

 Bay. As no specimens of Lynx fasciatus pallescens are available 

 for comparison I would hardly venture to identify ours with that 

 form, even though Merriam (1899, p. 104) refers specimens taken 

 on Mount Shasta to it. An adult male taken at Helena weighed 

 nineteen pounds. 



Reithrodontomys megalotis klamathensis Merriam 

 Klamath Harvest Mouse 

 It was not our good fortune to secure the harvest mouse from 

 Mayten, the type locality. Our camp there was rather unfortunately 

 situated in a dry rocky pasture and we were not conveniently near 

 to the hayfields where we might have found the species. But three 

 specimens from Scott River (nos. 13360-13362), and five from 

 Tower House (nos. 12788-12792) have been referred to this form 

 because of skull characters. The large skull, heavy rostrum, wider 

 brain-ease and relatively smaller bullae serve to distinguish our 

 specimens from B. m. longicaudus. But the coloration is practically 

 as dark as in longicaudus, so that our specimens might best be 

 considered intermediate, and nearest klamathensis. The hind foot 

 of four male specimens averages but 17 millimeters, as against an 

 average of 18.5 for two adults from the type locality of Jclamatht nsis, 

 as given by Merriam (1899, p. 93). One male (no. 12788) meas- 

 ures: total length, 147 millimeters; tail vertebrae, 77; hind foot, 18;
