126 Merriam JVW Moments Jrom California. 



Both were obtained by Aurelius Todd. The type specimen is a woolly 

 fulvous animal with a large hairy blackish tail and dark fore and hind 

 feet. The other specimen is pale buffy fulvous and seems to be a par 

 tial albino. Compared with the type of P. longieaudus, P. albipe* differs 

 strikingly, the body being coarsely grizzled brownish bister, like an 

 ordinary field mouse (Microtus}, instead of fulvous, the feet white in 

 stead of dark brown, the tail slender, scantily haired, and white under 

 neath, instead of large, hairy and blackish all round. 



The skull of the type of longfraudii* is reduced to fragments but the 

 parts that remain agree essentially with corresponding parts of the skull 

 from Meadows, Lane County, Oregon (No. 42, (521 9 ) Compared with 

 the latter the skull of albipes differs markedly in greater length and 

 narrowness, less spreading zygomata, narrower and longer braincase. 

 longer rostrum and nasals, larger bullas and longer interpterygoid fossa, 

 which is square anteriorly instead of rounded or angular. 



Measurement*. Type specimen ( $ ad.): total length 1(58: tail verte 

 bra 62; hind foot 19. 



Callospermophilus chrysodeirus trinitatis subsp. nov. 



Type from Trinity Mountains east of Hoopa Valley, California (alti 

 tude 5700 feet). No. 95,531, 9 ad. U. S. National Museum, Biological 

 Survey Collection. September 10, 1898. A'ernon Bailey. Original No. 

 6693. 



Characters. Size large: ground color dark: under side of tail dark 

 chestnut. In fall pelage similar to chrysodeirus, but larger; ground color 

 darker: inside of tail dark chestnut (instead of golden fulvous): skull 

 and teeth larger: nasals longer. 



Kern-arks. This spermophile, which is common in the Siskiyou, Sal 

 mon, and Trinity Mountains of northwestern California and south 

 western Oregon, is much larger and darker than chrysodeirus, and never, 

 so far as known, develops the golden mantle which covers the head and 

 shoulders of that species. In size it equals xaturatus of the Cascade 

 Range in the State of Washington, but differs widely from that species 

 in having the inner black stripe strongly developed (as in c/trysodeirux), 

 and the under side of the tail solid chestnut instead of grizzled fulvous. 



Measurements. Type specimen ( 9 ad.): total length 290: tail verte 

 brae 105; hind foot 44. Average of 6 specimens from type locality: total 

 length 283: tail vertebra 100: hind foot 43.
