Ochotona schisticeps schisticeps (Merriam) 



"Lagomys princeps," Cooper, Proc. Cal. Acad. Nat. Sci., 3, 

 1863, p. 69 (Record in minutes of meeting of Academy for 

 October 19, 1863, of exhibition by Dr. Cooper of specimens 

 from the summits of the Sierra Nevada) ; the same, 4, 1868, 

 p. 6 ("I obtained specimens near the snow line, above John- 

 son's Pass, Sierra Nevada . . , ,"). 



"Lagomys princeps?" Cooper, Zoology, in Cronise, The 

 Natural Wealth of California, 1868, p. 446 ("It inhabits the 

 Alpine summits of the Sierra Nevada, among enormous 

 granite boulders and banks of perpetual snow . . . ."). 



"Lagomys princeps," Cooper, Amer. Nat., 8, 1874, p. 15 

 (Footnote reference to Gabb's record of Ochotona in Lower 

 California. Cope, in Proc. Acad. Nat. Sci. Phil., 1868, p. 2, 

 erroneously records Gabb as having noted a specimen at 10,000 

 feet in the Sierra Nevada at 32° latitude). 



Specimens examined. — Three: Nos. 5612, 5628, Univ. 

 Calif. Mus. Vert. Zool. ; No. 145282, U. S. Nat. Mus. No. 

 5612: obverse of label "Lagomys princeps, Rich. — [printed 

 strip pasted on] 5 Summit Sierras Lat. 39°, Sept 26-63 J. 

 G. C"; reverse, eight measurements and a printed strip bear- 

 ing the name "Little Chief Hare". No. 5628: obverse of 

 label "1120 Lagomys princeps 9 juv. Summit Sierras, Lat., 

 39° Sept. 22-'63, J. G. C"; on the reverse side of the label 

 appear the words "immature 4/5 grov»^n". No. 145282: ob- 

 verse of label "Lagomys princeps $ Summit Sierras Lat. 39°, 

 Sept. 26 '63, J. G. C." ; reverse, eight measurements. 



Specimens prepared with skulls inside'; fore and hind feet 

 folded posteriorly and anteriorly, respectively, beneath body; 

 the hind feet in No. 145282 are somewhat torn and loosened. 



The locality where these examples were secured is probably 

 not far from the type locality of the species (Donner, Placer 

 Co., Calif.). The two specimens in the Museum of Verte- 

 brate Zoology (Nos. 5612, 5628) are in very different pelage 

 condition in spite of the fact that they were collected within 

 four days of each other. The female. No. 5628, taken Sep- 

 tember 22, is in worn summer pelage, and in spite of its being 

 marked "juv.", may have been a breeding animal. In such 

 an event, a delayed molt would not be unexpected. The male
