Coffee Creek was too low for them, but we secured oue at the 

 head of Grizzly Creek ; while the largest series from any one locality, 

 fourteen, came from Rush Creek. Five from Bear Creek and two 

 from Castle Lake make up the total of twenty-five (nos. 13299- 

 13323). Their occurrence at Castle Lake was one of the remark- 

 able features of that camp ; but a thick grove of red fir on a side- 

 hill showed that the squirrels as well as the trees may have been 

 more wide-spread there previous to the time of timber cutting. 

 We always selected a thick growth of firs in which to set the traps, 

 and put them at the bases of the larger trees. We often wished 

 we could see the animals in action, but they were as noiseless and 

 mysterious as their fur is soft and silky. 



Our series show T s an interesting variation in coloration and con- 

 dition of pelage. As a whole, it seemed to answer quite closely 

 to the original description of the form klamathensis (Merriam, 

 1897ft, p. 225), and this name we had accordingly adopted. Recently 

 our series was loaned to the United States Biological Survey where 

 a study of the group is in progress. A preliminary paper (Howell, 

 1915) announces the separation of the Trinity flying squirrel as a 

 recognizable race, the new name flaviventris being applied to it. 

 The type is no. 13,319, Mus. Vert. Zool.; head of Bear Creek, 6100 

 feet altitude, Trinity County, California ; collected August 13, 1911, 

 by Annie M. Alexander; original number 1775. 



Lepus washingtonii klamathensis Merriam 

 Oregon Showshoe Rabbit 

 One male (no. 13759), presumably adult, and an immature 

 female (no. 13760) were taken at Bear Creek, Trinity County, 

 August S and 15, respectively. In coloration and cranial char- 

 acters the adult specimen agrees closely with the latest published 

 description of L. w. klamathensis I Nelson, 1909, p. 107). Hitherto, 

 as far as known to the writer, this rabbit has been recorded only 

 from the vicinity of Fort Klamath, Oregon, and from the central 

 Sierra Nevada of California. Our adult example, in summer pelage, 

 may be described as follows: mixed grizzled fulvous and black 

 above; head and face of the same fulvous but with less black; pec- 

 toral collar fulvous with a sprinkling of white; chin, throat, and 

 belly white; a white stripe extending along the upper surface of
