Bison or Ameiv'can hvfalo {Bison hison (Linnaeus)). — One upper 

 permanent middle premolar of the right side, a portion of u ril), the 

 distal end of a left metatarsal canon bone, the proximal end of a right 

 metacarpal canon bone, a horn, and a small piece of skin. 



In the map accompanying- his memoir on the American bisons (1876), 

 Dr. J. A. Allen gives the most westerl}" range of this animal as just 

 beyond the Rio Grande, while on pages 125 and 126 the bison is 

 doubtfull}^ recorded as extending as far west as that river. The 

 present discovery extends its range to within a few miles of the west- 

 ern border of New Mexico, or about 110 miles farther west than hitherto 

 recorded. It is even probable that the bison ranged into Arizona. 

 As noted above by Doctor Hough, the bison remains were found deep 

 in the debris of the cave. He remarks on this discover}^ as follows: 



It seems clear that the buffalo existed in the neighborhood of this cave, from the 

 number of separate bones of the skeleton occurring here, as well as from the fact 

 that the Indians of this locality were never accustomed to carry with them masses 

 of buffalo flesh containing bones. Their method was universally to jerk the meat, 

 thus reducing it to small compass for carrying. The skins, however, were trans- 

 ported long distances and formed an article of trade between the Plains and Pueblo 

 Indians up to the time of the disappearance of the buffalo from the plains. 



Rock spermopliile {Citellus gramirmrus (Say)). — The greater part of 

 one skull, a portion of another, a scapula, and a few fragments of long 

 bones. 



Marmot or woodchuck {Marmota flaviventer or engelhardti ?).■ — The 

 anterior portion of a skull. 



I know of no marmots in collections from near this locality. The 

 type locality of Marmota flaviventer 'va "mountains between Texas and 

 California;" that for M. engelhardtl in in the Beaver Range Moun- 

 tains of Utah. 



Sonoran white-footed mouse {Peromyscus sonoriensis (Le Conte)). — 

 One dessicated specimen. 



Bio Grande icldte- footed mouse {Peromyscus tornillo Mearns). — One 

 dessicated specimen. 



This and the preceding species were identified b}^ Mr. W. H. 

 Osgood.

Pallid m uskrat {P/her zihethicus pallidus Mearns).^ — Two nearl}' com-
