The material necessary for the final determination of the status 

 and interrelations of the large Chipmunks of the Sierra Nevada 

 was collected by the Death Valley Expedition. The names that 

 have been given to these species are Tdmias (iiiadrimaculatus Gray 

 (1867), r. macrorhabdotes Merriam (1886), T. merriami Allen (1889), 

 and T. seaex Allen (1890). T. merriami is a very distinct species 

 from the one under consideration, and need not be discussed in 

 the present connection. (See p. 197.) 



Taiiiias qaadrimacidatas was described by Gray in 1867 from a 

 specimen from Michigan Bluff on the west slope of the Sierra in 

 Placer County, California. This specimen is in the red post- 

 breeding pelage, as shown by the original description and by a 

 note from Mr. Oldfield Thomas, ])ublished by Dr. J. A. Allen 

 (Bull. Am. Mus. Nat. Hist., Ill, p. 82, June, 1890). The species 

 was not recognized by EJaird, and Allen, in his Monograjjh of the 

 Sciuridffi (1877), gave it as a synonym of toivnsendi. 



In 1886 I described, under the name Tamias macrorhabdotes, a 

 long-eared and strikingly colored Chipmunk from Blue Canon 

 in the Sierra Nevada of central California. At this time no speci- 

 men of Gi'ixy'' s qiiadrimaculatas was available for comparison, the 

 only specimen extant (the type) being in the British Museum. 

 Subse(|uently I came in possession of a single specimen in rather 

 poor pelage from Nevada City, California, which differed from 

 the S2:)ecimens of macrorhabdotes from Blue Canon (the type lo- 

 cality) in having considerably smaller and less distinctly striped 

 ears, smaller post-auricular spots, the shoulders,, anterior half of 

 the back, and flanks deeply suffused with intense ferruginous, 

 and the hind feet of the same color, though duller. This speci- 

 men was correctly identified by both Doctor Allen and myself 

 as Gray's quadrimaculatus. Owing to the differences just men- 

 tioned. Doctor Allen, in his revision of the species of the genus 

 Tamias, concurred wuth me in admitting Gray's quadrimaculatus 

 and my macrorhabdotes as different species.
